FIELD: microbiology. SUBSTANCE: claimed method comprises cultivating bacteria or associations of bacteria containing amylolytic yeast under aeration conditions of culture medium containing, as carbon source, flour and/or cereal waste bran subjected to enzymic treatment with use of complex enzymic agents such as amylosubtilin and/or glucavamorin. The consumption rate of enzymes is from 0.25 % to 1.0% of absolutely dry matter. The claimed method affords one to obtain biomass with protein content of up to 50-60% and with full range of amino acids, vitamins B (including vitamin B12), H, E and F and also micro- and macroelements. Recycle of liquid phase (industrial condensate) to cultivation process affords waste-free technology, smaller amounts of water and mineral salts. EFFECT: more efficient preparation. 4 cl
