In some embodiments, the germinative compound (e.g. an amino acid, a purine nucleoside, a salt, or a sugar) is present in a mixture or composition of the invention at a concentration of about 0.01, 0.05, 0.1, 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 12.5, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 50, 100, 150, 200, 250, 300, 350, 400, 450, 500, 600, 700, 800, 900, or 1000 mM. Any of these values may be used to define a range for the concentration of the germinative compound in the mixture or composition. For example, in some embodiments, the concentration of the germinative compound in the mixture or composition is from about 0.01 mM to about 1000 mM, from about 0.01 mM to about 100 mM, or from about 0.1 mM to about 20 mM.
As is employed herein, the term "intimate mixture" refers to a mixture in which the spores and germinative compounds are maintained in proximate position until they reach an environment conducive to germination.
Such an intimate mixture can be achieved employing processes such as spray-drying, freeze-drying, vacuum-drying, air drying or drum drying. In a preferred embodiment, the intimate mixture is produced by spray-drying or freeze-drying. When forming such intimate mixtures, it is important that the spore and germinative compound are not mixed together under conditions which would allow the germinative compound to cause the spore to germinate, as this could cause premature germination with an adverse effect upon the storage life of the mixture. This can be avoided by employing separate streams in a spray-dryer, either by using two nozzles or a single nozzle which permits the simultaneous spraying of two separate streams; or by freeze- drying under conditions (for example temperatures) which are not conducive to germination. Premature germination may also be avoided by introducing the spore mass to a solution containing the germinative compound immediately prior to drying. In a preferred embodiment, the germinative compound is adsorbed to or absorbed by the fungus spore in the intimate mixture. In a further embodiment, the fungus spore and germinative compound are finely dispersed throughout the intimate mixture. In a still further embodiment, the fungus spore and germinative compound are microscopically dispersed throughout the intimate mixture, such that individual particles consisting essentially of fungus spores and individual particles consisting essentially of germinative compounds are not visible to the naked eye.
In one embodiment the intimate mixture is prepared by combining the fungus spore and germinative compound in a solution prior to drying. Preferably, the fungus spore and germinative compound are combined in a solution immediately prior to drying.
Although not wishing to be held to any theory, it is believed that the formation of an intimate mixture places the germinative compound in a proximate position where it can more preferably bind to the germination initiator sites of the spore when the mixture reaches an appropriate environment for germination. Such proximate position permits the germinative compound to outcompete any germination interfering compounds which may be present, with the result that a higher percentage of spores will be germinated. Due to the logarithmic growth of fungus once they enter the vegetative stage; such an increased percentage can quickly result in a several log increase in culture formation.
The present invention also relates to compositions comprising a mixture of a fungal spore and a germinative compound. In a preferred embodiment, the composition comprises an intimate mixture comprising (a) a fungal spore and (b) a germinative compound, wherein the spore and germinative compound are maintained in an inactive form such that the germinative compound will not induce germination of the spore until such composition is subjected to an activation environment.
As is employed herein, the term "activation environment" refers to an environment which permits the germinative compound and the spore to interact, such that the spore is induced to enter into a vegetative state. Such an activation environment may involve the addition of water (through rain, moisture in the soil, or water added to the coated plant propagation material prior to planting), or it may require a combination of factors such as temperature, moisture, pH or salinity. The compositions of this invention may further comprise an acceptable carrier. As is employed herein, the term "acceptable carrier" refers to a carrier which is typically employed in the field involved (for example a carrier typically employed in industrial, agricultural, aquacultural, environmental and/or probiotic applications) which does not adversely affect the bacterial strain involved. Such carriers are well known to those of ordinary skill in the art.
In a preferred embodiment, the carrier is an agriculturally acceptable carrier. In another preferred embodiment, the carrier is an aquaculturally acceptable carrier. In a further preferred embodiment, the carrier is suitable for environmental administration or bioremediation. For many industrial and/or agricultural applications, carriers include porous solid carriers such as talc, bentonite, clay, kaolin, diatomaceous earth, white carbon, vermiculite, slaked lime, siliceous sand, ammonium sulfate, and the like; as well as liquid carriers such as water, isopropyl alcohol, xylene, cyclohexanone, methylnaphthalene, and alkyl glycol and the like. For probiotic use, pharmaceutically acceptable carriers such as sugars and starches which are typically employed may be utilized.
The invention also provides a food product or pharmaceutical product comprising the aforementioned compositions.
The formation of a mixture of a germinative compound and a fungus spore (e.g. an intimate mixture) may enhance the utility of the fungus spore by increasing one or more traits of interest of the fungus spore, including but not limited to germination, growth, metabolism, enzyme activity and tolerance to environmental stresses such as low pH, high salt concentration, and exposure to toxic metals. In some embodiments, the mixture increases the trait of interest by at least 5, 10, 20, 30, 40 , 50, 60, 70, 80, 90, 100, 200, 300, 400 or 500% relative to a
corresponding fungus spore formulation that lacks a germinative compound.
In order to further enhance germination, it is preferred that the spore be shocked prior to the formation of the mixture. Spores may be shocked in a variety of standard methods, e.g., osmotic shock, heat shock, cold shock, pressure shock, deprivation of nutrients, and/or exposure to certain acids. Heat shock involves heating the spores for a sufficient period of time at a temperature sufficient to induce the production of heat shock proteins.
When employed in agricultural or industrial uses, such compositions may further comprise standard formulation aids such as surfactants, emulsifiers, other active ingredients, etc. so long as such other components do not interfere with germination or adversely affect the viability of the germinated spores.
The invention also provides a method for preparing a mixture of preparing a fungus spore and a germinative compound. In a preferred embodiment, the invention relates to a method for preparing a dried intimate mixture comprising a fungus spore and a germinative compound, the method comprising:
a) preparing a solution comprising a fungus spore and a germinative compound; and
b) drying the solution to obtain a dried intimate mixture comprising a fungus spore and a germinative compound, wherein the fungus spore and the germinative compound are maintained in proximate position until they reach an environment conducive to germination.

verruculosum, Glomus versiforme, Glomus viscosum, Gigaspora albida, Gigaspora decipiens, Gigaspora gigantean, Gigaspora margarita, and Gigaspora rosea.
Typically, such germinative compounds that are used in the aforementioned plant propagative materials are amino acids such as glycine and L-amino acids including L-alanine, L- arginine, L-aspartate, L-glutamate, L-histidine, L-isoleucine, L-lysine, L-methionine, L-serine, L-tryptophan, L-tyrosine, L-valine, L-proline, L-leucine, L-cysteine, L-threonine, L-glutamine, L-asparagine, L-phenylalanine and analogues thereof. Additional germinative compounds which may also be employed in the plant propagative materials include purine nucleosides (e.g. inosine and adenosine), salts (e.g. Calcium Chloride, Potassium Phosphate, Potassium Carbonate and Magnesium Sulphate), sugars (e.g. glucose and fructose). Nutrients, including dextrose, starches, and micronutrients which will aid in the growth of fungi once the spores have germinated may also be included.
Such amino acids can be employed in the plant propagative material as individual compounds, or in the form of polypeptides. In one embodiment the polypeptides are protein hydrolysates, for example casein hydrolysate. Useful polypeptides will typically comprise at least fifty percent amino acids which will function as germinants, such as L-alanine, L-valine, L- proline, L-leucine, L-cysteine, L-threonine, L-glutamine, L-asparagine, and L-phenylalanine, such percentages being based upon the number of amino acids in the polypeptide.
Accordingly, such compositions may comprise dry mixtures of the spore and germinative compound; or they may include other materials (for example, low temperature melting waxes) which prohibit the spore and germinative compound from interacting until required
environmental criteria have been reached. Additional materials that may be used in the composition to prevent the spore and germinative compound from interacting include, but are not limited to, surfactants, sequestering agents, plasticizers, colorants and dyes, brighteners, emulsifiers, flow agents, coalescing agents, defoaming agents, thickeners, waxes, fillers, polymers, wetting agents and anti-freezing agents. Further, such compositions may take the form of emulsions wherein the spore and germinative compound are kept from interacting due to their presence in different phases.
Preferably, but not necessarily, the spore and germinative compound are in intimate mixture with one another, which intimate mixture can be produced by spray-drying, freeze - drying, vacuum-drying, air drying or drum drying. In a preferred embodiment, the plant propagative material is coated with an intimate mixture as described above.
Such compositions may further comprise additional components, including co- germinants, nutrients, and formulation aids, provided that such additives do not induce the spore and the germinative compound to prematurely interact.
The plant propagative material may be coated with the fungus and germinative compound by any conventional means typically employed to coat seed or other germinative material, provided that such means does not adversely affect the viability of the spores and that such means does not result in the germinative compound prematurely converting the fungus into its vegetative state. Conventional means which may be employed include spray treatment, drip treatment, drench treatment, painting treatment, film-coat treatment, pellet-coat treatment and the like. Methods of seed coating are known in the art and are described, for example, in U.S. Pat. No. 7,989,391 and U.S. Pat. No. 5,849,320.
When applying such coating, it is important that the spore and germinative compound are not mixed together under conditions which would allow the germinative compound to cause the spore to germinate, as this could cause premature germination with an adverse effect upon the storage life of the mixture. One way in which this can be avoided is by employing separate streams in a spray-dryer, either by using two nozzles or a single nozzle which permits the simultaneous spraying of two separate streams; or by freeze-drying under conditions (for example temperatures) which are not conducive to germination.
In addition to biologically active ingredients, seed coating compositions may include many materials and additives that are either part of the formulations of the active ingredient or contribute to the handling qualities of the seed coating or its functionality and durability on the seed. An example of a coating additive is a coating polymer which binds the active ingredients to the seed. Seed-coating polymers may include, for example, but are not limited to, proteins, polysaccharides, polyesters, polyurethanes, polymers prepared from unsaturated monomers, and combinations thereof.
Other additives contributing to the handling qualities of the seed coating or its functionality and durability on the seed include but are not limited to surfactants, sequestering agents, plasticizers, colorants and dyes, brighteners, emulsifiers, flow agents, coalescing agents, defoaming agents, thickeners, waxes, bactericides, fillers, polymers, wetting agents and anti- freezing agents. The nature and action of such additives are well-known to those skilled in the art of formulation. Additives should not interfere with the action of the fungus.
Binders that are useful in the present invention preferably comprise an adhesive polymer that may be natural or synthetic and is without phytotoxic effect on the seed to be coated. The binder may be selected from polyvinyl acetates; polyvinyl acetate copolymers; ethylene vinyl acetate (EVA) copolymers; polyvinyl alcohols; polyvinyl alcohol copolymers; celluloses, including ethylcelluloses, methylcelluloses, hydroxymethylcelluloses, hydroxypropylcelluloses and carboxymethylcellulose; polyvinylpyrolidones; polysaccharides, including starch, modified starch, dextrins, maltodextrins, alginate and chitosans; fats; oils; proteins, including gelatin and zeins; gum arabics; shellacs; vinylidene chloride and vinylidene chloride copolymers; calcium lignosulfonates; acrylic copolymers; polyvinylacrylates; polyethylene oxide; acrylamide polymers and copolymers; polyhydroxyethyl acrylate, methylacrylamide monomers; and polychloroprene.
The amount of binder in the coating can vary, but will be in the range of about 0.01 to about 25% of the weight of the seed, more preferably from about 0.05 to about 15%, and even more preferably from about 0.1 % to about 10%.
The propagative material coating may optionally include a filler. The filler can be an absorbent or an inert filler, such as are known in the art, and may include woodflours, clays, activated carbon, sugars, diatomaceous earth, cereal flours, fine-grain inorganic solids, calcium carbonate, and the like. Clays and inorganic solids, which may be used, include calcium bentonite, kaolin, china clay, talc, perlite, mica, vermiculite, silicas, quartz powder,
montmorillonite and mixtures thereof. Sugars, which may be useful, include dextrin and maltodextrin. Cereal flours include wheat flour, oat flour and barley flour.
The filler is selected so that it will provide a proper microclimate for the seed, for example the filler is used to increase the loading rate of the active ingredients and to adjust the control-release of the active ingredients. The filler can aid in the production or process of coating the seed. The amount of filler can vary, but generally the weight of the filler components will be in the range of about 0.05 to about 75% of the seed weight, more preferably about 0.1 to about 50%, and even more preferably about 0.5% to 15%.
Optionally, a plasticizer can be used in the coating formulation. Plasticizers are typically used to make the film that is formed by the coating layer more flexible, to improve adhesion and spreadability, and to improve the speed of processing. Improved film flexibility is important to minimize chipping, breakage or flaking during storage, handling or sowing processes. Many plasticizers may be used, however, useful plasticizers include polyethylene glycol, glycerol, butylbenzylphthalate, glycol benzoates and related compounds. The range of plasticizer in the coating layer will be in the range of from about 0.1 to about 20% by weight.
The treated seeds may also be enveloped with a film overcoating to protect the active components coating. Such overcoatings are known in the art and may be applied using conventional fluidized bed and drum film coating techniques.
The invention also provides a method for enhancing the growth of a plant propagative material comprising treating a plant propagative material with the aforementioned compositions, wherein growth of the plant propagative material is enhanced relative to a corresponding control plant propagative material that is not treated with the composition.
In certain embodiments of the aforementioned method, the plant propagative material is treated with the composition by coating the plant propagative material with the composition as described above. In other embodiments of the aforementioned method, the plant propagative material may be treated with the composition by applying the composition to the plant growth medium before or after planting. For example, the composition may be applied to the soil by spraying or through an irrigation system. The composition may also be applied to the plant growth medium in a solid form, for example as a dried powder.

Example 6: Evaluation of germination, plant growth, and yield for maize seeds coated with a composition comprising a fungal spore and a germinative compound
Maize seeds are coated with compositions comprising various combinations of the fungal spores and germinative compounds listed in Example 5. Seed coating is performed by conventional means, such as those described in U.S. Pat. No. 7,989,391 and U.S. Pat. No.
5,849,320. The following treatments are evaluated: A. Seed coated with an intimate mixture of the fungal spores and the germinative compound
B. Seed coated with a conventional mixture of the fungal spores and the germinative compound
C. Seed coated with the fungal spores alone
D. Uncoated seed
Seed germination rates are measured in greenhouse and field trials by measuring seedling emergence each day beginning on the first day that plants emerge and continuing for three weeks after the first date of emergence. Yield is measured by harvesting the mature ears and drying them for three days in an oven at 37°C. The ears are then threshed and the seeds are collected and counted. Total seed weight is also measured by weighing the seed harvested from each plant.
It is found that maize seeds coated with an intimate mixture of the fungal spores and germinative compound have higher seed germination rates and higher yields than seed coated with a conventional mixture of the fungal spores, seed coated with fungal spores alone, or uncoated seed.
