METHOD OF STORAGE OF MICROORGANISM CULTURES Russian patent published in 2002 - IPC

FIELD: microbiology. SUBSTANCE: invention relates to culturing and storage of microorganisms in synthetic nutrient media. Method involves addition of sodium selenate (Na₂SeO₄) an aqueous solution in final concentration 10^-4-10^-6 g/l of medium to nutrient medium designated for storage of bacterial or mycelial culture that provides the retention of all necessary parameters of storing culture for a long time without reinoculation. Invention ensures to increase storage time of mycelial and bacterial culture-producers of biologically active substances and can be used in production of seeding mycelium in mushroom-growing farms. EFFECT: improved method of storage. 3 tbl, 4 ex
