LIQUID FOR SELECTION OF MICROBIOLOGICAL SAMPLES AT SUBZERO TEMPERATURES Russian patent published in 2016 - IPC C12Q1/04 

FIELD: microbiology; pharmaceutics.

SUBSTANCE: disclosed is a flushing neutralising fluid for sampling of microorganisms at negative temperatures. Liquid contains 7.5 mass percents of sodium hyposulphite solution, propylene glycol - 30.0 mass percents or 40.0 mass percents, and, if required, 10 mass percents of glycerine. Invention ensures possibility of sampling at temperatures down to -30°C.

EFFECT: samples storage life without deterioration of viability of microorganisms in neutralising fluid without addition of glycerine increases up to 3 days, with addition of glycerine - up to 10 days.
