Animal feedstuff having beneficial properties is obtained by adding to a substrate one or more fungal species of the kind that excretes substances into said substrate during its growth which are beneficial to the health, growth or weight gain of an animal, or animals to which the feedstuff is intended and allowing the fungus to grow and/or ferment on the substrate. Suitable substrates are cereal grains, residue of cereal grains, agricultural primary products, agricultural waste products, and other cellulosic materials or a combination of one or more of the same. Suitable fungus species include Cordyceps species, Ganoderma species, Grifola species, Trametes Species, Lentinula species, Antrodia species, Agaricus species, Tremella species, Pleurotus species, Lentinus species, Polypore species, Agaricales species, Ascomycetes species and Basidiomycetes species. Some substrates such as certain agricultural waste products and cellulosic material are not suitable for animal consumption per se but become suitable as a result the fungal growth and fermantation by the fungus or fungi on and in them.

Systems are provided for preventing post harvest fungal diseases of food systems, such as but not limited to fresh produce, such as but not limited to berries (e.g., blueberries). For example, various anti-fungal compounds can incorporated or encapsulated into cyclodextrins, such as but not limited to α, β and/or γ cyclodextrins. The encapsulated anti-fungal materials can be used alone (e.g., brought into proximity to the produce) or incorporated into film and/or packaging materials that are used in the packing and/or storing of produce. By way of a non-limiting example, the anti-fungal compounds can include volatile compounds such as but not limited to acetaldehyde, hexanal and 2E-hexenal. The cyclodextrins provide controlled release of the volatiles over a period of at least several days such that they prevent or inhibit fungal growth, including but not limited to several species of the Colletotrichum, Altermaria, Botrytis, Penicillium and/or Aspergillus genera.

The present invention also relates to a biologically active compound called coronamycin obtained from endophytic Streptomycetes isolated from higher plants. The present invention further relates to compositions of such compounds and to methods of protecting plants against attack by a plant pathogen and methods of inhibiting bacterial growth, fungal growth, viral infection, growth of parasitic organisms, and cancer cell growth with such compositions.

The invention relates to a waterborne hinokitiol wood preservative and a preparation method thereof, and is used for solving the problems that hinokitiol giving a natural corrosion resistance to wood has poor water solubility and is difficult to use. The wood preservative comprises the components according to mol ratio: 0.2-2 mol of hinokitiol, 1 mol of a solubility promoter, and 0.01-1 mol of a tannin extract (the molar ratio calculated according to the content of phenolic hydroxyl group). The wood preservative is used for processing the wood, and when the mass concentration of hinokitiol is about 1%, the resistance of the processed wood to Aspergillus niger, Penicillium citrinum, Trichoderma is up to 100%, and the fungal growth is completely inhibited; and moreover, the molding resistance of the processed wood to Coriolus versicolor and Gloeophyllum trabeum can achieve strong molding resistance level.

The invention discloses a broad-spectrum biological bactericidal air filtration material and a preparation method thereof. The invention is not only applicable to the general families and business departments with the need of air purification, but is also applicable to the semiconductor, pharmaceutical, hospitals and other environments with higher requirements of cleanliness.

Animal nutrition compositions include a carrier and a fermentation product applied to the carrier. Liquid fermentation products are fluidly applied to dry carriers, such as phyllosilicates or other earthen components, while mixing and applying air flow, under appropriate temperature and pH conditions, to bind the fermentation product to the carrier and dry the reaction product to appropriate moisture content. Fermentation products are also mixed with liquid carriers, such as water. Fermentation products include components of a microbial fermentation culture, such as liquid medium, microbial cellular components, and fermentation metabolites produced by microorganisms. Some compositions include a pH buffering agent and/or additional components to further enhance beneficial effects of the composition, such as improved weight gain and feed conversion, reduced gut lesions, harmful gut bacteria count, and decreased mortality. Compositions can be mixed with animal feeds or otherwise administered. Compositions can inhibit fungal growth on animal feeds.
