Abstract: The invention provides biologically active compositions comprising oligosaccharides, and which are produced by growing a fungal culture, and are at least partially purified for use. The compositions of the invention have antibacterial, antifungal and nematicidal activity, and are thus useful to reduce the impact of such pathogens on growing plants, to reduce the occurrence of such pathogens on surfaces and in substances, and to treat infections caused by such pathogens in animals and humans. The invention also provides methods for producing such compositions from certain fungal cultures.

Abstract: Dermal drops that, when applied topically to animal subjects, can ameliorate symptoms of conditions such as diabetes and Parkinson's disease are prepared as concentrates of the culture filtrate of a Basidiomycete fungus grown under appropriate conditions. The concentrate can also be used as a convenient source of liquid compost factor.

Abstract: The invention provides compositions derived from brown-rot fungi that are suitable for use in bioremediation and similar applications where it is desirable to transform a target compound, often a toxic organic compound, into a different compound or compounds having more acceptable properties. The compositions are suitable for treating aqueous solutions or suspensions to reduce the amount of an undesired organic compound present, usually as one step in a treatment process to render the solution or suspension more suitable for environmental release. The invention also provides improved methods for growing fungal cultures for production of culture fluids.

Abstract: A substantially microbe-free composition containing plant growth regulators is produced by culturing a fungal spawn on high carbohydrate medium under suitable conditions. The culture filtrate is sterilized, formulated, and used to enhance plant growth.

Abstract: A clear aqueous emulsion of a complex comprising a moiety having a hydrophilic core to which is covalently bound the backbone of at least one monounsaturated C16-C20 fatty acid and appropriate surfactants is effective in controlling agricultural pests, including nematodes.

Abstract: A pesticide composition that includes a metabolite from a fungus selected from homeocarpic basidiomycetes and homeocarpic ascomycetes is produced. In one embodiment, the fungus from which the metabolite is derived is one grown under conditions effective to substantially suppress fruiting of the fungus. More particular the pesticide compositions are provided comprising a fungal metabolite derived from a fungus selected from the group Ganoderma spp., Lactiporus spp. Lentinus spp. Morchella spp., and Pleurotus spp. The pesticide composition may be produced by culturing the fungus on a medium containing vegetable oil and a surfactant. Alternatively a filtrate from a culture of the fungus is added to the medium containing vegetable oil and a surfactant, and mixed until pesticidal activity develops.

In one embodiment, the fungus from which the metabolite is derived is one grown under conditions effective to substantially suppress fruiting of the fungus. More particular examples of the invention include pesticide compositions comprising a fungal metabolite derived from a fungus selected from the group Ganoderma spp., Laetiporus spp., Lentinus spp., Morchella spp., and Pleurotus spp.

Abstract: An improved substrate for mushrooms that is essentially cellulose-free comprising a major portion of grain and minor portions of nutritional supplements. The grain is partially sterilized by boiling in order to kill bacteria, cooled in order to induce germination of the heat resistant spores, and steam sterilized before the germinated spores have matured sufficiently to create new spores. The substate can be used to grow fungi, including mushrooms, especially shiitake.
