Relative expression level of lipBJ10 in different recombinant strains (from BL21-00 to BL21-06). Data were normalized to the housekeeping gene E. coli 16s. Results are shown as relative expression ratios compared with expression in the non-fusion expression strain (the recombinant E. coli BL21-00). The results are means ± one standard deviation for three replicates and differences between different strains were statistically significant at a P value of 0.05
