Mutagenesis and Breeding of Fermentation Strains about Cold Water Infused Tea

Abstract

Abstract: A cellulase-decomposing bacterium SW3 was screened out from tea, and mutagenized with UV and NaNO2. The first isolation was conducted according to the method of distinct zone of clearing in cellulase-congo red agar medium. The second isolation was conducted according to the test of filter paper enzyme activity through liquid fermentation. SW355 is 62.9% higher than the original strain SW3, and it has a stable property in transmissibility.

Key words: cellulase, mutation, UV, NaNO₂
