The present disclosure relates generally to fungus organisms and methods of crossbreeding fungus organisms. In particular, methods of making fungus organism hybrids with novel or enhanced phytochemicals are described.
Phytochemicals are secondary metabolite compounds produced by plant and fungus species in nature. Phytochemicals can be extracted from plant and fungus species and used for industrial, health, medicinal, or recreational purposes. Some of the phytochemicals found in plants and fungi are alkaloids, flavonoids, glycosides, and phenols. It is believed that these phytochemicals help the body ward off toxins, recover from illness, and alleviate pain.
While naturally occurring phytochemicals have many beneficial properties, it would be desirable to produce fungus organisms with novel or enhanced phytochemicals to provide even more industrial, health, medicinal, or recreational benefits. Novel phytochemicals are phytochemicals that do not exist in nature. Enhanced phytochemicals are phytochemicals already known to exist, but at higher potency or in a higher concentration than they exist in nature. There would be advantages to fungus organisms with novel or enhanced phytochemicals tailored to provide certain benefits, such as increased treatment potential for a given disease or condition.
Thus, there exists a need for fungus organisms with novel or enhanced phytochemicals to improve on conventional ways of acquiring phytochemicals and/or to provide new benefits beyond what conventional phytochemicals can provide. Examples of fungus organisms with new and useful phytochemicals relevant to the needs existing in the field are discussed below.
The present disclosure is directed to methods of crossbreeding dikaryotic fungus organisms to yield a hybrid fungus organism with a novel or enhanced phytochemical. The methods include providing a first growth medium. The methods further include placing a first dikaryotic fungus organism with a first phytochemical on the first growth medium. In an additional step, the methods include placing a second dikaryotic fungus organism with a second phytochemical on the first growth medium adjacent to the first dikaryotic fungus organism.
The presently disclosed methods further include allowing the first dikaryotic fungus organism to replicate and to form a first colony on the first growth medium. In a subsequent step, the methods include allowing the second dikaryotic fungus organism to replicate and to form a second colony on the first growth medium. The methods proceed to include allowing the first colony and the second colony to expand until they intersect along a clamp line where the first colony and the second colony exchange genetic material between them to yield a hybrid fungus organism with a novel or enhanced phytochemical.
In some examples, the method further comprises harvesting the crossbred fungus organism by removing the clamp line from the first growth medium. In such examples, the method may further comprise transferring the clamp line to a second growth medium. Moreover, such methods may further comprise allowing the clamp line to replicate and form a third colony. The method may further comprise transferring the third colony to a food source.
In some examples, the method further comprises allowing the third colony to replicate on the food source and harvesting the third colony after it has replicated on the food source. Additionally, the method may further comprise transferring the third colony to a substrate and allowing the third colony to fruit into a fruit body on the substrate.
In some examples, the substrate is manure. In other examples, the substrate is wood. In certain examples, the fruit body is a spore-producing mushroom. In select examples, the fruit body is a sporeless mushroom. In some examples, the fruit body is a truffle. In particular examples, the fruit body has an elevated concentration of one or more novel phytochemicals useful for treating cancer and Parkinson's disease.
In some examples, the first dikaryotic fungus organism is Trametes versicolor or a sub-variant thereof. The second dikaryotic fungus organism may be Ganoderma lucidum or a sub-variant thereof. The novel hybrid fungus organism may contain novel or enhanced phytochemical forms of one or more of polysaccharide and triterpenoid.
In certain examples, the first dikaryotic fungus organism is Psilocybe cyanescens or a sub-variant thereof. The second dikaryotic fungus organism may be Psilocybe cubensis or a sub-variant thereof. The novel hybrid fungus organism may contain novel or enhanced psychoactive phytochemicals. The enhanced psychoactive phytochemicals may include one or more of novel or enhanced forms of psilocybin, psilocin, and baeocystin.

Methods of Crossbreeding Fungus Organisms to Yield Fungus Organism Hybrids with Novel or Enhanced Phytochemicals
With reference to
With reference to
At step 112, method 100 includes allowing the first colony and the second colony to expand until they intersect along a clamp line where the first colony and the second colony exchange genetic material between them to yield a crossbred fungus organism. Method 100 continues with harvesting the crossbred fungus organism by removing the clamp line at step 114. At step 116, method 100 includes transferring the clamp line to a second growth medium.
Method 100 further includes allowing the clamp line to replicate and form a third colony at step 118. At step 120, method 100 includes transferring the third colony to a food source. Step 122 of method 100 is allowing the third colony to replicate on the food source.
At step 124, method 100 includes harvesting the third colony after it has replicated. Step 126 of method 100 is transferring the third colony to a substrate. Method 100 further includes allowing the third colony to fruit into a fruit body at step 128.
An optional step 130 of method 100 may be taken after the first colony and the second colony intersect along a clamp line at step 112. Step 130 is dividing the first growth medium into portions and transferring the portions to separate growth mediums.
In some examples, the methods of cross breeding fungus organisms do not include one or more steps depicted in
Providing a First Growth Medium
Providing a first growth medium at step 102 establishes a shared environment for two distinct fungus organisms to replicate and exchange genetic material through hyphal anastomosis fusion.
The first growth medium may be any currently known or later developed type of growth medium suitable for a given species of fungi. Suitable growth mediums include agar, gellen gum, liquid culture solution, grain, and any other nutrient rich media.
The size and shape of the first growth medium may be selected to suit the needs of a given application. For example, the first growth medium may be supported within a standard petri dish.
Placing Distinct Fungus Organisms on the First Growth Medium
Placing first and second fungus organisms on the first growth medium adjacent to each other at steps 104 and 106 functions to seed the first growth medium with fungus organisms to be crossbred in method 100. In the methods described herein, the first and second fungus organisms are selected from the genus Psilocybe or Panaeolus. The second fungus organism is selected to be different than the first fungus organism because method 100 functions to crossbreed two distinct fungus organisms.
In some examples, the first fungus organism is selected from the genus Psilocybe and the second fungus organism is selected from the genus Panaeolus. In other examples, the first fungus organism and the second fungus organism are both selected from the genus Psilocybe, but are different Psilocybe species or Psilocybe species variants. In still other examples, the first fungus organism and the second fungus organism are both selected from the genus Panaeolus, but are different Panaeolus species or Panaeolus species variants. In certain examples, one or more of the first fungus organism and the second fungus organism produces a sporeless fruit body.
In one particular example, the first fungus organism is Trametes versicolor, known commercially as Turkey Tail mushroom, and the second fungus organism is Ganoderma lucidum, known commercially as Reishi mushroom. In another specific example, the first fungus organism is Psilocybe cyanescens and the second fungus organism is Psilocybe cubensis.
Other fungus organism pairings tested to be suitable for the methods described herein include Psilocybe cubensis and Psilocybe semilanceata; Psilocybe cubensis and Psilocybe azurescens; Psilocybe mexicana and Psilocybe galindoi; the Golden Halo variant of Psilocybe cubensis and Psilocybe azurescens; the Golden Halo variant of Psilocybe cubensis and Psilocybe stuntzii; and the Enigma variant of Psilocybe cubensis and the Roller Coaster variant of Psilocybe cubensis. A wide range of fungus organism pairs are contemplated beyond those expressly described. Additional examples of fungus organism pairings are described below in the Specific Examples section below.
Allowing the Fungus Organisms to Replicate
Allowing the first and second fungus organisms to replicate enables the first and second colonies of the first and second fungus organisms, respectively, to form at steps 108 and 110. The first and second fungus organisms will draw nutrients from the first growth medium and naturally replicate over time.
The time, temperature, and pressure conditions for steps 108 and 110 may be selected within wide ranges as appropriate for given fungus organisms. In some examples, the fungus organisms on the growth medium are held at room temperature and atmospheric pressure until the first and second colonies have grown large enough to intersect with each other.
Allowing Colonies to Intersect
Allowing the first and second colonies to expand and intersect at step 112 serves to form a clamp line between the colonies. Forming a clamp line enables hyphal anastomosis fusion and exchanges genetic material between the first fungus organism and the second fungus organism. The exchange of genetic material yields a crossbred fungus organism.
The time required for the colonies to expand sufficiently to intersect and form a clamp line at step 112 will depend on a variety of factors. For example, different fungus organisms will have different replication rates and different growth mediums will enable different replication rates for a given fungus organism. The proximity of the two colonies on the first growth medium will also be a factor in the time needed to form a clamp line.
The time, temperature, and pressure conditions for step 112 may be selected within wide ranges as appropriate for given fungus organisms. In some examples, the fungus organisms on the growth medium are held at room temperature and atmospheric pressure until the first and second colonies have grown large enough to intersect with each other.
Dividing and Transferring Portions of the First Growth Medium
Dividing the first growth medium into portions and transferring the portions to separate growth mediums at step 130 after step 112 is an option to accelerate subsequent crossbreeding methods. Utilizing optional step 130 allows subsequent methods to effectively start new methods 100 at step 112. The new growth mediums on which portions of the first growth medium are placed will enable the already established colonies of fungus organisms from the first growth medium to continue replicating and intersecting along clamp lines. Optional step 130 may be described as anastomosis fusion.
Optional step 130 can multiply the crossbred fungus organism formed at step 112 by the divisions made of the first growth medium. For example, dividing the first growth medium into fourths and transferring the divisions to four separate growth mediums to replicate can multiply the crossbred fungus organism by approximately four times. Similarly, dividing the first growth medium into thirds and transferring the divisions to three separate growth mediums to replicate can multiply the crossbred fungus organism by approximately three times.
Harvesting and Transferring a Crossbred Fungus Organism
Harvesting the crossbred fungus organism at step 114 and transferring it to a second growth medium at step 116 serves to lay the foundation for replicating the crossbred fungus organism. Harvesting the crossbred fungus organism at step 114 is accomplished by removing the clamp line formed on the first growth medium (or on a separate growth medium receiving a division of a prior first growth medium if optional step 130 was utilized previously). Removing the clamp line may include cutting out the clamp line from a petri dish.
Transferring the clamp line to a second growth medium at step 116 establishes a new growth environment for the crossbred fungus organism to replicate. The second growth medium may be any currently known or later developed type of growth medium suitable for the crossbred fungus organism. Suitable growth mediums include agar, gellen gum, liquid culture solution, grain, and any other nutrient rich media. In some examples, the second growth medium is the same as the first growth medium.
The size and shape of the second growth medium may be selected to suit the needs of a given application. For example, the second growth medium may be supported within a standard petri dish.
Forming a Third Colony
Allowing the clamp line to replicate and form a third colony on the second growth medium at step 118 increases the quantity of the crossbred fungus organism and prepares it for further replication on a grain food source. The third colony may be allowed to grow until there is a sufficient quantity of the crossbred fungus organism and the third colony is sufficiently viable to be replicated on a grain food source.
The time required to form a sufficiently robust third colony of the crossbred fungus organism at step 118 will depend on a variety of factors. For example, different fungus organisms will have different replication rates and different growth mediums will enable different replication rates for a given fungus organism.
The time, temperature, and pressure conditions for step 118 may be selected within wide ranges as appropriate for given crossbred fungus organisms. In some examples, the crossbred fungus organism on the second growth medium is held at room temperature and atmospheric pressure until the third colony occupies a substantial majority of the second growth medium's top surface area.
Replicating the Third Colony on a Food Source
Transferring the third colony to a food source at step 120 enables the third colony to replicate extensively. The food source may be any currently known or later developed nutrient-rich food suitable for a given crossbred fungus organism. Suitable food sources for step 120 include grains, brans, and mixtures of sawdust and bran.
Allowing the third colony to replicate on the grain food source at step 122 increases the quantity of the crossbred fungus organism and prepares it for fruiting when harvested at step 124 and transferred to a substrate at step 126. The third colony may be allowed to replicate until there is a sufficient quantity of the crossbred fungus organism and the third colony is sufficiently viable to fruit when transferred to a substrate.
The time required to form a sufficiently robust third colony of the crossbred fungus organism on the food source at step 122 will depend on a variety of factors. For example, different fungus organisms will have different replication rates and different food sources will enable different replication rates for a given fungus organism.
The time, temperature, and pressure conditions for step 122 may be selected within wide ranges as appropriate for given crossbred fungus organisms. In some examples, the crossbred fungus organism on the second growth medium is held at room temperature and atmospheric pressure until the third colony occupies a substantial majority of the food source surface area.
Harvesting and Transferring the Replicated Third Colony
Harvesting the crossbred fungus organism at step 124 and transferring it to a substrate at step 126 serves to lay the foundation for fruiting the crossbred fungus organism. Harvesting the crossbred fungus organism from the food source at step 124 is accomplished by separating the food source with the crossbred fungus third colony growing on it from the excess food source that does not have significant amounts of the crossbred fungus third colony growing on it. In some examples, the entire food source is transferred to the substrate at steps 124 and 126.
Transferring the crossbred fungus organism to a substrate at step 126 establishes a fruiting environment for the crossbred fungus organism. The substrate may be any currently known or later developed type of substrate for the crossbred fungus organism. Suitable substrates include manure, wood, and soil.
The size, shape, and quantity of the substrate may be selected to suit the needs of a given application. For example, the substrate may be laid out in trays or beds.
Fruiting the Third Colony
Allowing the third colony to fruit on the substrate at step 128 creates a fruit body. The fruit body may be harvested and used for a variety of applications, including therapeutic research and treatments.
In some examples, the fruit body formed at step 128 has an elevated concentration of one or more psychoactive compounds. The psychoactive compounds with elevated concentrations may be psilocybin, psilocin, and/or baeocystin.
The form and characteristics of the fruit body will be based on the fungus organisms crossbred and may be quite varied. In some examples, the fruit body is a spore-producing mushroom. In other examples, the fruit body is a sporeless mushroom. In certain examples, the fruit body is a truffle. A wide variety of additional or alternative fruting body phenotypes and characteristics will result from crossbreeding different fungus organisms.
The time required to fruit the third colony into fruiting bodies on the substrate at step 128 will depend on a variety of factors. For example, different fungus organisms will have different fruiting rates and different substrates will enable different fruiting rates for a given fungus organism.
The time, temperature, and pressure conditions for step 128 may be selected within wide ranges as appropriate for given crossbred fungus organisms. In some examples, the crossbred fungus organism on the substrate is held at room temperature and atmospheric pressure until the fruiting bodies occupy a substantial majority of the substrate surface area.
