Аннотация:The presented work shows the possibility of consistent application of the method of oxidative depolymerization of green biomass (straw, sawdust, and lignine) and biological acid hydrolysis by an optimal and enhanced acidogenic consortium with the addition of an inducer, glycerin, to the medium. The data obtained are important for evaluating the efficiency of the technology for the production of biofuels from hardly decomposable lignine-containing ones due to their transformation into VFAs and ethanol.
