Aspects of the integrated use of non-traditional plant raw materials (Sorghum) in biotechnological industries

An urgent problem of the processing industries is the expansion of the raw material base and the reduction of waste generation. The review examines the prospects of using non-traditional plant raw materials and modern biotechnological processes of its directed conversion into microbial synthesis products that ensure resource conservation and effective replacement of traditional grain crops, using the example of alcohol production. Based on the analysis of scientific publications, systematization and generalization of research results, current data on the influence of the composition of the main polymers of grain sorghum on the level of synthesis of ethanol and lysine are presented, which made it possible to identify significant characteristics of grain of promising sorghum varieties. The possibility of complex use of a multicomponent sorghum plant (grain and stem juice) is confirmed not only as a raw material to produce ethyl alcohol, but also as a source of carbohydrates for microbial conversion into lysine. The importance of microbial synthesis in solving environmental problems of alcohol production has been revealed, which consists in obtaining, along with the target product, an additional feed lysine-protein additive when cultivating Brevibacterium on media containing barda remaining after fermentation of wort by yeast Saccharomus cerevisiae. The demonstrated possibility of complex biotechnological processing of grain and sorghum stem juice into ethanol and L-lysine creates prerequisites for expanding research in the field of biosynthetic technologies to produce other valuable products of microbial synthesis based on the use of multicomponent sorghum plant as a substrate for the cultivation of industrial strains of microorganisms - producers of functional ingredients and biologically active substances.
