This disclosure relates to organophosphorus and organosulfurous compounds and compositions thereof, and methods of using them in various applications.
Microbial growth and fouling on surfaces and in water causes contamination, operational inefficiencies, and can result in human illnesses. Microbial contamination and/or fouling are problematic in processing industries such as agro-industry, food, water, healthcare, pharmaceutical, personal hygiene and beauty products. Contamination may consist of biological, chemical, or physical substances in contact with surfaces, water, as well, as in products, food, and plants.
Fouling may consist of both “microfouling” and “macrofouling.” Microfouling is the attachment of microorganisms such as bacteria, yeast, fungi, and microalgae on surfaces to form biofilm or to each other to form clumps. Microfouling causes corrosion, scale, slime, clogging, and clumping. Macrofouling is the attachment of foulers which are eukaryotes such as, barnacles, mussels and algae to surfaces. Macrofouling forms on the outside of underwater structures, pipelines, and ship hulls, and on the inside of ballast tanks, intake pipes used to carry water to cooling towers of all traditional and renewable energy plants, etc. Fouling results in operational inefficiencies and increased costs, including frequent replacement of degraded and fouled equipment, operational downtime and labor costs to apply treatments and remedies, and increased fuel consumption by over 50% (with the corresponding greenhouse gas emissions) to overcome clogging and hydrodynamic drag.
Another problem related to fouling occurs in fermentation facilities and algae ponds. The fermentation culture organisms such as, yeast, microalgae, and bacteria (including cyanobacteria) form clumps or foul on the surface of the water and wetted-surfaces. The clumping and fouling causes a decrease in oxygenation to the cell cultures and decreases biomass production and in turn decreases productivity (g/L/day) and yield. In addition, fermentation cultures get contaminated by bacteria that additionally compete with the fermentation culture for food sources. The contaminated fermentation cultures need to be cleaned and the contamination can cause the system to crash. Algae pond crashes account for an estimated 30% of current production on algae farms. In addition, the contamination can cause unwanted changes in flavor of the product.
The traditional remedies to remove microfouling and macrofouling are expensive and short term: physical removal (scraping, pressure washing, etc.), shock treatments of hazardous biocides, etc. Chemical remedies are additionally costly because they require HAZMAT protocols for shipping, storage, use, and disposal. Due to their toxic overload of ecosystems and organisms, many chemical remedies are being restricted or banned by regulators worldwide. For example, the Ports of Amsterdam and San Diego have banned copper from marine hull paint. Water authorities are limiting the level of chlorine permitted in water treatments. Regulators are banning endocrine disruptors and other biocides that bioaccumulate and harm plant and animal health—including that of humans. Thus, there is a need for novel treatment for microfouling and macrofouling.
Preservatives are natural or synthesized chemical compounds that maintain the integrity of a product's formulation, surface, or material by slowing or preventing microbial growth or undesirable chemical changes. For example, wood preservatives in treatments and/or coatings protect wood and lumber from mold, decay, pest infestation, decomposition from climate, surrounding conditions, etc. Preservatives in consumer and industrial products prevent contamination by mold, fungi, and bacteria, preservatives in food and beverages prevent decomposition, etc.
Provided herein are methods for treating or inhibiting contamination in water, on a surface, and/or in a product, the methods comprising administrating a composition in an effective amount comprising one or more of an organophosphorous compound, organosulfurous compound and/or antimicrobial, and/or sonication.

The following three reagents were obtained through Biodefense and Emerging Infections Research Resources Repository (BEI Resources), NIAID, NIH: Staphylococcus aureus, Strain A152006045 AKA VRS7, Vancomycin-Resistant (VRSA) NR-46417; Pseudomonas aeruginosa, P179, NR-31041, Multi-drug Resistant; and E. coli serotype O157:H7 ATCC 51657, NR-8, Multi-drug Resistant. Burkholderia cepacian (BC) ATCC 25416, Ralstonia pickettii (RP) ATCC 27511, and silver-resistant Cuprividus metallidurans (CM) ATCC 43123 were obtained from the NASA Marshall Space Flight Center. Microorganisms were cultured Tryptic Soy Broth (BD Bacto) growth medium prepared as per the manufacturer's instructions unless otherwise stated. Lactobacillus fermentum and L. delbrueckii were cultured in Lactobacillus MRS culture media (BD Difco) prepared as per the manufacturer's instructions. Overnight cultures of bacterial strains were adjusted to final target inoculum concentrations between 105-107 CFU/ml. For the test methods, E. coli, P. aeruginosa, S. aureus were cultured at 37° C. for 24-hours. A. niger, B. cepacian, R. pickettii, and C. metaffidurans were cultured at 30° C. for 2-3 days.
Minimum inhibitory concentration (MIC) broth microdilution method was performed according to CLSI guidelines (CLSI M07-A10: Methods for Dilution Antimicrobial Susceptibility Tests for Bacteria that Grow Aerobically; Approved Standard—Tenth Edition). Assays were performed in duplicates on more than one occasion in a 96 well microtiter plate. The treatments were tested at a range of concentrations that were compared to controls that contained the appropriate media without the presence of any inhibitor. Turbidity (growth) was either measured visually or in a SpectraMax i3 Pate Reader (Molecular Devices) at 600 nm. The MIC of an inhibitor was determined by the lowest concentration without visible growth.
Minimum bactericidal concentration (MBC) was performed according to CLSI guidelines (CLSI M26-A: Methods for Determining Bactericidal Activity of Antimicrobial Agents; Approved Guideline).
Biofilm inhibition imaging was determined by growing bacteria in a black-walled optically-clear bottom 96 well plate (Nunc) at a 45° angle to promote biofilm formation prior to imaging. The treatments were tested ata range of concentrations: 0.24, 0.12, 0.06, 0.03, 0.015, 0.007, 0.0038, 0.0019% (v/v). After incubation with the treatments, the culture media was removed and the remaining adhered biofilm was stained with a two-color fluorescent stain using the FilmTracer LIVE/DEAD Biofilm Viability Kit (Molecular Probes) for 30 minutes and then biofilm was washed with sterile water. The live cells in the biofilm are stained green with SYTO 9 green fluorescent nucleic acid stain and dead cells are stained red with the red-fluorescent nucleic acid stain, propidium iodide. Images of the biofilms were taken with a Cytation 5 Cell Imaging Reader (Olympus) at excitation/emissions of 469/525 nm for SYTO 9 green and 531/593 nm for propidium iodide. These were compared to control biofilms that contained the appropriate growth media and bacteria without the presence of any inhibitor.
Minimum biofilm eradicating concentration (MBEC) was performed according to the ASTM standard (ASTM E2799-12; Standard Test Method for Testing Disinfectant Efficacy against Pseudomonas aeruginosa Biofilm using the MBEC Assay). Assays were performed in duplicates on more than one occasion.
The antimicrobial test results for the compounds are presented in Table 1.

Antibiofilm activity against mixed species Burkholderia cepacia, Ralstonia pickettii, and silver-resistant Cuprividus metallidurans was determined for SDBS+Antifoam SE15 formula using the FilmTracer LIVE/DEAD Biofilm Viability Kit (Molecular Probes). The antibiofilm results are in
Based on these series of results against Burkholderia cepacia, Ralstonia pickettii, and silver-resistant Cuprividus metallidurans, SDBS 0.06%+Antifoam SE15 0.003% formula were used to determine its biofilm management efficacy in wastewater tanks at a configuration similar to that currently employed for the Water Processor Assembly (WPA). In this Phase, five tanks were filled with 55 L of wastewater ersatz (Table 4) and a mixed species inoculum concentration of 1×105 CFU/ml. Two tanks were designated as control tanks (Tank 1 and Tank 5), for which no treatment was added. Two had an SDBS concentration of 0.06%, and one had an SDBS concentration of 0.05%. These periodically cycle back and forth from a transfer tank, mimicking the cycling process on the WPA. The schematic for this cycling process for an individual tank is laid out in
The antibiofilm treatment SDBS at 0.06% (Tank 2 and Tank 3) and 0.05% (Tank 4) inhibited the growth of the mixed species biofilm forming bacteria (B. cepacia, R. pickettii, and silver-resistant C. metallidurans) with a 5-log (99.999%), 5-log (99.999%), and 4-log (99.99%), reduction respectively. The inhibition occurred rapidly, within the first day. The activity was sustained with a single treatment for over 8 months (Table 5).
