The synthesis of biologically valuable protein, polysaccharides, incl. chitin-glucan-mannan complex non-pathogenic strain of the fungus Aspergillus oryzae in the process of solid-phase cultivation on the secondary raw materials processing industries of the AIC. The content of crude protein on the medium with sunflower meal was 78.0%, which was 2 times higher than the initial medium (38.6%); a higher accumulation of proteins was achieved on media with sunflower meal and grain bard (4:1) - 86.4%. It was established that the media containing grain bard in its composition provided the highest accumulation of polysaccharides - 25.0 - 30.0%, which is 1.5 times higher than on the initial medium. Introduction to the composition of the nutrient medium of sunflower meal in the amount of 20 and 80% of grain bards allowed to increase the yield of the chitin-glucan complex to 32%, while the amount of protein was 76%. The content of essential amino acids of microbial biomass grown on the medium with sunflower meal increased 1.8 times and amounted to 143.7 mg/g. The main increase in the content of essential amino acids accounted for such amino acids as methionine, isoleucine, leucine, phenylalanine, tryptophan, valine. The obtained results can be used for the production of a protein-polysaccharide feed enrichment with sorbing properties. |
