Fig. 2From: Development of an efficient autoinducible expression system by promoter engineering in Bacillus subtilis Identification of the integration expression level and pattern of GFP in BSG1683 and BSG1684. The fragment containing the P srfA promoter and the gfp gene was separately integrated into the chromosome of B. subtilis 168 and BSG1682, and the resulting recombinant strains BSG1683 and BSG1684 were cultivated for GFP expressionBack to article page
