诱变

This paper focused on the breeding of an L-lactic acid producing bacteria Lactobacillus easei YBQ1-1, studying the characteristics, medium components, pH and metabolic network of the mutant YBQH2-14 obtained after being selected.Using UV irradiation, L.casei YBQH2-14 was selected in the different plate media such as the medium with high concentration of glucose, lactic acid , CaCO3 -Bromocresol purple and KMnO4 -KBr.
