摘要

FIELD: biotechnology.;SUBSTANCE: according to the first variant of proposed method sodium benzoate is added to indicated powder media and preparations based on thereof to obtain mixtures containing ground sodium benzoate particles being at least 50% of particles by mass have sizes not exceeding 10 mcm. According to the second variant the composition containing sodium benzoate, friable organic acid and/or anti-caking agent, and/or chalk is added in the definite ratio of components. Invention provides improvement of odor of bacterial media to be treated and preparations based on thereof and also improved their friability and reduces their caking.;EFFECT: improved treatment method.;15 cl, 1 tbl, 2 ex
