Delivery of disease control in aquaculture and agriculture using microbes containing bioactive proteins
A microbial biomass, made from algae, bacteria, fungi, yeast, or combinations thereof, provides a feed for animals raised either in agriculture or aquaculture. A feed additive, and a therapeutic composition can also be made from a microbial biomass of algae, bacteria, fungi, yeast, or combinations thereof. The feed, feed additive, and therapeutic composition can comprise one or more proteins, peptides, antibodies, antibody fragments, or a combination thereof, wherein said proteins, peptides, antibodies, antibody fragments, or a combination thereof are non-native to the microbes of the biomass. The biomass can have therapeutic, bioactive, nutritional, and/or immunogenic properties.
1. A method of treating shrimp, wherein the method comprises feeding to the shrimp a fermented and homogenized fungal biomass containing at least one bioactive acidic bactericidal or bacteriostatic peptide expressed by the fungi during fermentation and cultured fungal cells, wherein the bioactive peptide is non-native to the fungi, and wherein the fermented and homogenized fungal biomass is fed to the shrimp in an amount sufficient to produce a bactericidal or bacteriostatic effect in the shrimp.
2. The method of claim 1 , wherein the fermented and homogenized fungal biomass further comprises a protein from an infectious bacterium, which stimulates an immunologic response.
3. The method of claim 1 , wherein the fermented and homogenized fungal biomass comprises yeast.
4. The method of claim 1 , wherein the fermented and homogenized fungal biomass comprises Mortierella.
