摘    要:87株芽孢杆菌经过2次菌液上清液赖氨酸含量测定,筛选出1株赖氨酸产量较高的菌株YB83,其在LB上清发酵液中赖氨酸含量达186.85μg/mL,比对照组提高27.68%,该菌通过菌落形态、生理生化特征和分子生物学鉴定为枯草芽孢杆菌。

关 键 词:芽孢杆菌  赖氨酸  筛选

Abstract:87 strains of Bacillus spp. as initial bacteria were applied to select and breed high-yield lysine strain. After twice screening by determining the lysine content of bacterial supermatant,one strain named YB83 was screened out,whose lysine content was 186.85 μg/mL,27.68% higher than LB control medium.According to the morphological and physiochemical properties,combining with 16S rDNA gene sequence and its position in the phylogenetic tree,strain YB83 was finally identified as Bacillus subtilis.
Keywords:Bacillus spp    Lys  screening
