<p>A method which can be used in fermenting carbohydrate substrates of plant origin for producing C1-C5 alcohols, and for synthesis of higher alcohols, and other oxygen-containing compounds. Since C6 and higher alcohols are not obtainable by a direct biochemical route, it is proposed to synthesize these using known chemical reactions, wherein the raw material for synthesis is biogas and lower C2-C5 alcohols obtained by the inventive method wherein the amino acids leucine, isoleucine, and valine, or a mixture thereof, optionally obtained from yeast autolysate, is used as a biocatalyst at the stage of fermentation. It is also proposed to use wasters of C2-C5 alcohols production for obtaining biogas. The method offers a solution to the following problems: to considerably increase the yield of C2-C5 alcohols in fermentation of carbohydrate substrates; to increase by 1.5-2.0 times the productivity of the fermentation in terms of C2-C5 alcohols production; to utilize the protein-containing waste for C2-C5 alcohols production, to reach highest efficiency of biomass utilization in producing higher oxygen-containing compounds and hydrocarbons.</p> |
