PREPARATION COMPRISING A PROBIOTIC STRAIN OF THE GENUS BACILLUS MEGATERIUM AND A POLYUNSATURATED FATTY ACID COMPONENT

The current invention concerns a preparation comprising at least one probiotic strain belonging to the genus Bacillus megaterium or an extract of Bacillus megaterium, and a polyunsaturated fatty acid component comprising at least one omega-3 or omega-6 fatty acid selected from eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), arachidonic acid (ARA), alpha linolenic acid, stearidonic acid, eicosatetraenoic acid, docosapentaenoic acid, linoleic acid, γ-linolenic acid and/or derivatives thereof.

Dietary intake of omega-3 fatty acids, namely alpha-linoleic acid (ALA), EPA and DHA, is beneficial for human health, in particular with respect to e.g. the amelioration of rheumatoid arthritis and reduction of cardiovascular disease risk factors [1, 2]. Various seafood products are a source of dietary EPA/DHA, but their consumption is often not sufficient to meet the recommended dietary allowance (typically 500 mg EPA and DHA per day) [3]. This gap is closed by the widespread use of dietary supplements or fortified foods containing omega-3 fatty acids [4]. Dietary supplements are concentrated sources of nutrients or other substances with a nutritional or physiological effect, whose purpose is to supplement the normal diet (www.efsa.europa.eu/en/topics/topic/food-supplements). For example, omega-3 fatty acid supplements often contain either triglycerides or omega-3 ethyl esters of EPA/DHA from fish oil, krill oil, or algae.

Omega-3 fatty acids in general have anti-inflammatory, cardio- and neuroprotective effects [2, 5]. Their modes of action involve e.g. direct scavenging of reactive oxygen species, alteration of cell membrane fluidity, which subsequently affects cellular signaling events, modulation of the activity of transcription factors such as PPARG and NFKappaB that orchestrate the biosynthesis of pro-and anti-inflammatory cytokines, and competitive exclusion of substrates that are converted to proinflammatory cytokines by cyclooxygenases and lipoxygenases.

More recently, several oxygenation products of omega-3 and omega-6 fatty acids have been identified and functionally characterized as crucial mediators of their beneficial health effects, in particular with respect to the amelioration of chronic inflammatory conditions [6]. These products include maresins (MaR), E- and D-series resolvins (RvE and RvD), protectins, lipoxins, and precursors thereof such as 18-hydroxy-eicosapentaenoic acid (18-HEPE), 17-hydroxy-docosahexaenoic acid (17-HDHA), and 17,18-epoxyeicosatetraenoic acid (17,18-EEQ), collectively referred to as specialized pro-resolving lipid mediators (SPM). SPM are endogenously formed by lipoxygenases, cyclooxygenase-2, and cytochrome P450 monooxygenases (CYP450), and act as potent agonists of active inflammation resolution, signaling via G-protein coupled receptors at nanomolar concentrations. The effectiveness of SPM against a multitude of infectious and inflammatory diseases has been demonstrated in studies with rodents [6]. For example, RvE1, RvD2, protectin D1 (PD1), and LXA4 enhance the clearance of pathogenic Pseudomonas gingivalis [7], E. coli [8], Herpes simples [9], Candida [10], H5N1 Influenza [11].

LXA4, LXB4, RvE1, RvE3, RvD1-5, RvD2, PD1, MaR1, MaR2 are protective in models of periodontitis, cystic fibrosis, neuroinflammation, ischemic stroke, Alzheimer's disease [12], atherosclerosis [13], non-alcoholic fatty liver disease [14], corneal injury [15], retinopathy [16], glaucoma [17], colitis [18], asthma [19, 20], insulin resistance [14], arthritis [21], and pain [22].

Moreover, several precursors of SPM have themselves been shown to exert pro-resolving effects. For example, 18-hydroxy-eicosapentaenoic acid (18-HEPE) counteracts the development of cardiovascular diseases by inhibiting monocyte adhesion to vascular endothelial cells [23] and by inhibiting pressure overload-induced maladaptive cardiac remodeling [24]. Similarly, 17,18-EEQ has cardio-protective, anti-arrhythmic, vasodilatory, and anti-inflammatory properties [5]. Paracrine secretion of ARA-derived 15-HETE by enteric glial cells supports gut barrier function, a process that is impaired in e.g. Crohn's disease [25].

Translation of these promising preclinical findings towards improving human health has however shown to be challenging. Direct delivery of SPM by intravenous or intraperitoneal injection, as has been done in experimental studies, is not feasible for humans, particularly not in the context of preventive approaches. Oral delivery of SPM- or SPM precursor-containing supplements or foods is not reasonable because of their relatively short half-life in biological fluids, which are therefore unlikely to reach their target tissue. In this regard WO 2017/041094 discloses that a concentrated esterified fish oil contains only ˜0.0005% 18-HEPE and 17-HDHA, and even enrichment of these SPM precursors by supercritical fluid extraction yields not more than 0.05% (18-HEPE+17-HDHA)/total omega-3.

Clinical trials with EPA/DHA have yielded inconclusive or null results, especially for patients with inflammatory bowel diseases, asthma, and traits of the metabolic syndrome [2]. This lack of benefit for humans contrasts with the effective treatment of the respective animal disease models by SPM [6]. We reason that the conversion of omega-3 (and omega-6) to SPM is a crucial step which is decisive for delivering successful outcomes from any interventions aiming to prevent, cure, or treat inflammatory diseases with polyunsaturated fatty acids (PUFA). We also conceive that the SPM-producing machinery is dysfunctional under certain conditions. This idea is supported by findings of reduced (local or circulating) SPM levels in diabetic wounds [26], metabolic syndrome [27], asthma [19, 28], ulcerative colitis [29], Crohn's disease [25], and periodontitis [30], as well as reduced expression or activity of SPM-producing enzymes in severe asthma [28], ulcerative colitis [29], cystic fibrosis [31], periodontitis [30], and Alzheimer's disease [12].

The objective of this invention is therefore to provide a technology that promotes SPM formation inside an organism to provide a benefit to humans and animals suffering from the above-mentioned conditions and that are in need of novel strategies to prevent, ameliorate or cure such and similar conditions, where supplementation of omega-3s alone has yielded little or no success.

This goal is achieved by the invention combining a suitable omega-3 source with a newly discovered microbial SPM-producer in a suitable formulation, such that the combination technology delivers enhanced and/or targeted efficacy compared to an omega-3 source alone. The suitable formulation allows for concomitant release of the components in gastrointestinal sections distal to the small intestine, thereby preventing the omega-3 source from being absorbed in the small intestine and making it more available for metabolization by the microbial SPM-producer.

Biosynthesis of SPM has been described in detail for eukaryotic cells, in particular for granulocytes and monocytes. Macrophages can express all enzymes that are required for SPM biosynthesis; other cell types expressing only selected enzymes can do so together with complementing cells. ALOX5 is found in mast cells, ALOX12 in skin and epithelial cells, ALOX15 in dendritic and enteric glial cells [25], and COX-2 and CYP450 isoforms in epithelial cells.

Given that the gut microbiota determines an individual's response to food ingredients and subsequently modifies health outcomes, we identified it as a target for our technological approach of facilitated endogenous SPM production. Microbiota-targeted strategies in general include the application of prebiotics and probiotics with the intention to modify the composition and activity of the microbiota. Probiotics are live microorganisms, which confer a health benefit on the host when administered in adequate amounts (FAO-WHO; Probiotics in food. Health and nutritional properties and guidelines for evaluation; FAO Food and Nutritional Paper 85, 2006). Prebiotics support the growth of beneficial microorganisms. Prebiotic effects of omega-3 fatty acids have been described [32, 33], but vice versa, possible metabolic impact of gut microbes on omega-3s remained to be determined and are disclosed in this invention. Occurrence of oxygen-consuming enzymes in gut-residing microorganisms is limited; cyclooxygenases and lipoxygenases appear to be absent from gastrointestinal bacteria and archaea, with the exception of a 15-lipoxygenase expressed by pathogenic Pseudomonas aeruginosa [34]. CYP450 monooxygenases have been detected in the Genus Bacillus [35]. CYP102A1, also named CYP450BM-3, is a bifunctional enzyme found in the species Bacillus megaterium that catalyzes the NADPH-dependent hydroxylation of polyunsaturated fatty acids via consecutive oxygenase and reductase activities. This P450 system consists of a polypeptide chain with two different domains, one containing the hemoprotein and the other one containing a FAD-reductase. This bacterial cytochrome P450 class is soluble and obtains the electrons necessary for the reaction mechanism from an NADH-dependent FAD-containing reductase via an iron-sulphur protein of the [2Fe-2S] type [36]. Purified CYP450BM-3 derived from an expression vector construct has been shown to generate 18-HEPE from EPA in a cell-free reaction [37]. However, a possible application of such reaction in a probiotic or synbiotic strategy, wherein a wildtype probiotic strain is the “catalyst” for activation of extracellular EPA/DHA to 18-HEPE or other SPM, and more important, makes these molecules available to the host, has not been described. Furthermore, oxygenation of omega-3 or omega-6 compounds to any other SPM or bioactive lipid mediator by any other probiotic microorganism has thus far not been described.

The present invention is directed to preparation comprising at least one probiotic strain belonging to the genus Bacillus megaterium, and a polyunsaturated fatty acid component comprising at least one omega-3 or omega-6 fatty acid selected from eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), arachidonic acid (ARA), alpha linolenic acid, stearidonic acid, eicosatetraenoic acid, docosapentaenoic acid, linoleic acid, γ-linolenic acid, wherein the polyunsaturated fatty acid component comprises an omega-3 or omega-6 fatty acid salt.

This new preparation promotes the formation of various SPM in the intestinal lumen, whereby they become available to the host and exert physiological functions therein. The oxygen required for biosynthesis of SPM from EPA/DHA is available in the intestinal lumen: gas in the human rectum reportably contains 0.3-1.8% oxygen [38]. Furthermore, a radial partitioning of intraluminal oxygen, increasing from 1 to 40 mmHg pO2 towards the (vascularized) cecal mucosa, has been described for mice [39], indicating that aerotolerant microbes associated with the mucosa face a relatively oxygen-rich environment that allows for oxygen-dependent biochemical reactions.

Bacteria of the species Bacillus megaterium were found to be especially suitable for this effect. Therefore, the probiotic strain comprises a strain of this species. It is a crucial feature of the invention that the strains lead to extracellular amounts of SPM, which is a prerequisite for eliciting physiological effects on the host. We disclose Bacillus megaterium-dependent production of extracellular SPM at nanomolar levels—whereby some SPM are physiologically active at picomolar levels [6]-, exceeding those reported for human plasma [27, 40, 41] and partly for human milk [42]. According to the present invention, it is both feasible to use whole cells and lysed bacterial cells, encompassing all components of the bacterial cell. Cell extracts may also be used.

Bacillus megaterium has recently been detected in human fecal [43] and saliva [44] samples, showing that these bacteria are residents of the human gut. The invention therefore also covers the use of omega-3 or omega-6 components to promote the formation of various SPM in the gastrointestinal tract by gastrointestinal microbiota through e.g. strains of the species Bacillus megaterium as naturally occurring gut inhabitants.

The cells of the strains of the current invention may be present, in particular in the compositions of the current invention, as spores (which are dormant), as vegetative cells (which are growing), as transition state cells (which are transitioning from growth phase to sporulation phase) or as a combination of at least two, in particular all of these types of cells. Therefore, in a preferred embodiment, the probiotic strain is present in a dormant form or as vegetative cells.

In a preferred embodiment, the omega-3 or omega-6 fatty acids are either in the form of free fatty acids, salts, natural triglycerides, fish oil, phospholipid esters or ethyl esters.

In a further preferred configuration, the fatty acids are selected from the omega-3 fatty acids EPA and DHA or wherein the omega-6 fatty acid component is ARA.

An additional configuration of the present invention is a combination of any of the above-mentioned compositions with 5-Aminolevulinic Acid, a compound that enhances heme biosynthesis [45] and thereby may trigger oxygenase activities of Bacillus megaterium.

In a preferred embodiment the probiotic strain is selected from one or more of the following: Bacillus megaterium DSM 32963, DSM 33296 or DSM 33299.

In an advantageous configuration EPA and DHA are either in the form of free fatty acids, salts, natural triglycerides, fish oil, phospholipid esters or omega-3 ethyl esters.

EPA and DHA were effectively transformed by probiotic strains to SPM when they were added as fatty acid salts, whose production and application were disclosed previously.

WORKING EXAMPLES
Example 1: The Strains Bacillus megaterium DSM 32963, DSM 33296 and DSM 33299 Each Possess Genetic Sequences for a Cytochrome P450 Monooxygenases (CYP450)

The strains Bacillus megaterium DSM 32963, DSM 33296 and DSM 33299 were isolated each from a soil sample from a pristine garden in east Westphalia. They have been deposited with the DSMZ on Nov. 27, 2018 (DSM 32963) and on Oct. 17, 2019 under the provisions of the Budapest Treaty on the International Recognition of the Deposit of Microorganisms for the Purpose of Patent Procedure under the accession number as mentioned before in the name of Evonik Degussa GmbH.

The genome sequence of B. megaterium DSM 32963 contains a gene [SEQ ID No: 7] encoding a protein with an identity of 97,9% at the amino acid level to P450 BM3 (CYP102A1) of B. megaterium ATCC 14581 (AAA87602.1). This enzyme incorporates both, a P450 oxygenase and a NADPH:P-450 reductase[46]. The natural substrates of P450 BM3 were analyzed to be long chain fatty acids (C12 to C20), which are exclusively hydroxylated at the subterminal positions (ω-1 to ω-3)[47].

Lower sequence similarities on amino acid level ranging from 21,1% to 30,5% on partial sequence hits were observed to sequences identified within the genome sequence of B. megaterium DSM 32963 compared to P450 BM3. These further potential cytochrome genes might have similar functions compared to P450 BM3 [Seq ID No: 8-12] (see table 1).

The genome sequence of B. megaterium DSM 33296 contains a gene [SEQ ID No: 19] encoding a protein with an identity of 98,9% at the amino acid level to P450 BM3 (CYP102A1) of B. megaterium ATCC 14581 (AAA87602.1). This enzyme incorporates both, a P450 oxygenase and a NADPH:P-450 reductase[46]. The natural substrates of P450 BM3 were analyzed to be long chain fatty acids (C12 to C20), which are exclusively hydroxylated at the subterminal positions (ω-1 to ω-3)[47].

Lower sequence similarities on amino acid level ranging from 21,5% to 30,7% on partial sequence hits were observed to sequences identified within the genome sequence of B. megaterium DSM 33296 compared to P450 BM3. These further potential cytochrome genes might have similar functions compared to P450 BM3 [Seq ID No: 20-24] (see table 2).

Example 2: Preparation of Omega-3 Fatty Acid Dispersions with Dioleylphosphatidylcholine (DOPC) in Phosphate Buffer

To prepare formulations of omega-3 fatty acid dispersions 0.8 g of dioleylphosphatidylcholine (DOPC, Lipoid GmbH) were dissolved in 1 ml ethanol. 0.2 g of fish oil (Omega-3 1400, Doppelherz®), omega-3 ethyl ester (PronovaPure® 500:200 EE, BASF) or lysine salt of free omega-3 fatty acid in form of omega-3 lysine salt (AvailOm®, Evonik) were added and dissolved. In the case of free omega-3 fatty acid salt, 20 μl of distilled water were added to dissolve the product completely.

The lysine salt of free omega-3 fatty acid in form of omega-3 lysine salt (AvailOm®, Evonik) contains around 67% of fatty acids and high amounts of the omega-3 fatty acids EPA and DHA and small amounts of the omega-3 fatty acid docosapentaenoic acid and the omega-6 fatty acids arachidonic acid, docosatetraenoic acid and docosaenoic acid isomer.

1 ml of the respective solutions was added dropwise to 20 ml of a 0.1 M phosphate buffer, pH=8, at a temperature of 45° C. and under intense stirring. Afterwards the dispersion was put on ice and sonified for 15 minutes to generate nanometer scale dispersions, presumably liposomes (Branson Sonifier, 100% amplitude, 50% impuls). Finally, the dispersions were sterile filtered through 0.2 μm syringe filters. The resulting dispersions were characterized with regards to particle size in via dynamic light scattering (DLS) measurements (Zetasizer Nano ZS, Malvern). The dispersions contained 40 g/I phospholipids and 10 g/I omega-3 fatty acids or esters.

Example 3: The Strain B. megaterium DSM 32963 is Able to Produce Intracellularly 18-Hydroxy-Eicosapentaenoic Acid (18-HEPE)

For B. megaterium DSM 32963 an associated intracellularly activity of SPM-producing enzyme(s) could be demonstrated. From 10 ml Luria Bertami broth (LB, Thermo Fisher Scientific) with 0.1% Glucose (LBG) a culture of B. megaterium DSM 32963 was grown for 24 h at 30° C. and 200 rpm in a 100 ml flask. The complete culture was transferred to a 200 ml main culture in LBG. The main culture was grown for 6 h at 30° C. and 200 rpm in a 2 l flask. The cell culture was then harvested in 10 ml portions, the supernatant removed by centrifugation (15 min, 4000 rpm, room temperature) and the cell pellet resuspended in 10 ml LBG and 2 ml of supplements (table 2), respectively. These cultures were incubated in 100 ml shaking flasks for 16 h at 30° C. and 200 rpm.

Different forms of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) sources were added to the B. megaterium DSM 32963 cell cultures to a final concentration of 0.4 g/I in form of omega-3 lysine salt (AvailOm® by Evonik), fish oil (Omega-3 1400 by Doppelherz®), and omega-3 ethyl ester (PronovaPure® 500:200 EE by BASF). These substances were added as sonificated emulsions and as dispersion formulations (preparation described in example 2), respectively.

DOPC formulation without omega-3 fatty acid content, and PBS buffer were used as controls without EPA.

The supernatants were separated by centrifugation (15 min, 4000 rpm, room temperature), and the cell cultures were then each harvested. Afterwards, the supernatants were diluted with a solvent consisting of a water/acetonitrile mixture (ratio supernatants: solvent was 1:2, solvent composition: 65% H₂O, pH8 and 35% MeCN). Pellets were freeze dried overnight and resuspended in a solvent consisting of a water/acetonitrile mixture (ratio pellet: solvent was 1:2, solvent composition: 65% H₂O, pH8 and 35% MeCN). The cell disruption was carried out in Lysing Matrix tubes (0.1 mm silica spheres) in a Ribolyser.

The cell homogenate (and the diluted supernatant) was filtered and then used for the detection of 18-hydroxy-eicosapentaenoic acid (18-HEPE) by LC/ESI-MS analysis (Agilent QQQ 6420, Gemini 3μ C6-Phenyl) in positive SIM-Mode at m/z 318 as well as the precursor compound EPA at m/z 302.

The addition of EPA, in form of omega-3 lysine salt, omega-3 ethyl ester, omega-3 lysine salt dispersions with DOPC, or fish oil dispersions with DOPC to the B. megaterium cells resulted in a cell associated (=intracellular+extracellular adsorbed) accumulation of 18-HEPE (table 3). By far the highest value of intracellular 18-HEPE was achieved by the addition of omega-3 lysine salt; it was tenfold higher than in the other approaches.

Example 4: The Synbiotic Combination of Bacillus megaterium DSM 32963 and Dispersion Formulation of Omega-3 Fatty Acid Salt AvailOm® Leads to Extracellular Amounts of 18-HEPE

To investigate the amount of extracellularly appearing 18-HEPE, the B. megaterium DSM 32963 cells were cultivated as described in example 1. The cells were resuspended in 10 ml LBG or LBG containing 9.76 g/I FeSSIF-V2 (biorelevant.com), which is a mixture of taurocholate, phospholipids and other components designed to simulate bile surfactants, and 2 ml of supplements (table 2) were added, respectively. Additionally, the supplements were also added respectively to the different media in shaking flasks without cells and treated under the same conditions (controls). The 18-HEPE concentrations of the culture supernatants and controls were determined after incubation at 16 h, 30° C. and 200 rpm (table 4). It could be shown that the Bacillus megaterium DSM 32963 cells are able to synthesize 18-HEPE from omega-3 lysine salt (AvailOm®) dispersions, which is extracellularly detectable. Of note, the omega-3 4 18-HEPE conversion rate detected by this method is up to 0.075, which exceeds the basal content of 18-HEPE of 0.0005% in an esterified fish oil, disclosed by WO 2017/041094. More importantly, we discovered that the omega-3 lysine salt is converted by Bacillus megaterium strains to a multitude of (final) SPM products at even higher concentrations than 18-HEPE (see example 6), which is of physiological relevance.

Example 5: Biotransformation of EPA by Different Bacillus Species

To investigate the ability of different Bacillus species to produce intracellularly 18-HEPE, cells of different species were cultivated as described in example 1. The cells were resuspended in 10 ml LBG containing 9.76 g/I FeSSIF-V2 (biorelevant.com), which is a mixture of taurocholate, phospholipids and other components designed to simulate bile surfactants, and 1.2 ml of the omega-3 lysine salt dispersion with DOPC were added, respectively. The internal 18-HEPE concentrations of the cells after incubation for 16 hat 30° C. and 200 rpm were determined as described in example 3.

Only the Bacillus megaterium cells were able to synthesize 18-HEPE internally from omega-3 lysine salt (AvailOm®) dispersions, whereby B.subtilis, B. amyloliquefaciens, B. pumilus and B. licheniformis were not.

Example 6: The Production of SPM by Bacillus megaterium DSM 32963 from Omega-3 Fatty Acid Salt AvailOm® Under Different Culture Conditions

Lipidometabolomics:

Bacterial supernatant samples were subjected to lipid extraction using RP-phase solid phase extraction and subsequently analyzed by ultra performance liquid chromatography ESI tandem mass spectrometry (UPLC-MS/MS) according to a published procedure [48]. Under these conditions approximately 40 different LM, including 5-hydroxy-eicosapentaenoic acid 5-HEPE, 8-HEPE, 11-HEPE, 12-HEPE, 15-HEPE, 18-HEPE, 5-hydroxy-eicosatetraenoic acid (5-HETE), 8-HETE, 11-HETE, 12-HETE, 15-HETE, 4-hydroxy-DHA (4-HDHA), 7-HDHA, 13-HDHA, 14-HDHA, 17-HDHA, lipoxin A₄(LXA4), LXB4, resolvin E1 (RvE1), RvE3, resolvin D1-5 (RvD1-5), AT-RvD1, RvD2, protectin D1 (PD1), AT-PD1, maresin 1(MaR1), MaR2, plus 4 fatty acid substrates can be detected with a lower limit of detection of 1 pg.

To investigate if Bacillus megaterium is capable of producing other PUFA oxygenation products in addition to 18-HEPE, a lipidometabolomics screening of supernatants from Bacillus megaterium strain 32963 cultured as in example 4 with AvailOm® was performed, either dissolved or in a dispersion formulation, with or without bile acids. Cell-free preparations of AvailOm® formulations were treated and analyzed in parallel and served as controls for non-enzymatic, spontaneous formation of oxygenation products. Values given in table 6 display net concentrations of products formed, i.e. after subtraction of control values. As can be seen, numerous oxygenation products including SPM have been formed by the bacteria. Concentrations of several SPM exceed by far the concentrations of SPM found in human plasma samples, which are typically in a range of ˜20-100 pg/ml [27, 40, 41]. For comparison, human breast milk contains ˜6.000 pg/ml RvE1 and ˜10.000 pg/ml RvD1 [42]. Given the fact that SPM exert receptor-mediated effects in vitro and in vivo in rodents in the nM or even pM range [6], findings displayed in table 6 strongly imply the physiological and therapeutic importance of our invention.

The type of PUFA formulation had a great impact on product levels, which were generally higher in the presence of PUFA dispersion formulations and/or the addition of bile acids as solubilizers. In parallel, abundance of mono-hydroxylated SPM precursors 5-HEPE, 11-HEPE, 12-HEPE, 15-HEPE, 18-HEPE, 5-HETE, 8-HETE, and 9-NODE was lower in these samples compared to samples treated with AvailOm in absence of dispersion formulation and bile acids. This can be explained by an increased conversion of these precursors to di- and trihydroxylated fatty acids.

Example 7: The Production of SPM from a Dispersion Formulation of Omega-3 Fatty Acid Salt AvailOm® by Other Bacillus megaterium Strains

47 additional Bacillus megaterium strains sourced from various habitats were screened for their SPM production capacity to determine if this is a general phenomenon of the species Bacillus megaterium and to detect strain-specific differences in types and quantities of SPM being produced. Cells were cultured as detailed in example 4, with dispersion formulation of AvailOm® serving as omega-3 fatty acid source. Cell-free preparations of AvailOm® were treated and analyzed in parallel and served as controls for non-enzymatic, spontaneous formation of oxygenation products. It was observed that all tested strains produced measurable (>1pg/ml) amounts of various SPM and precursors thereof, that these amounts were hugely different between the strains (up to 2.000 fold), and that concentrations of RvE3 were particularly high (up to 1.3 μg/ml) in most of the strains.

Values given in table 7 display net concentrations of PUFA oxygenation products formed by two of the top performing strains, Bacillus megaterium DSM 33296 and Bacillus megaterium DSM 33299.
