FIELD: biotechnology. SUBSTANCE: production of glycerin and succinic acid during fermentation of biomass and during distillation is accelerated by using special variant of the method (e.g. immobilization of yeast colls and their concentration, definite values of pH and osmotic pressure). Then glycerin and succinic acid are reduced with the help of pulp for clarifying, separated and purified. EFFECT: improves efficiency of the method. 6 cl, 6 tbl
