Fig. 4From: Manipulating the position of DNA expression cassettes using location tags fused to dCas9 (Cas9-Lag) to improve metabolic pathway efficiencyAstaxanthin titer and yield of engineered strains CAR025. Three repeats were performed for each strain, and the error bars represent standard deviation. The significance of differences was calculated by Student’s t-test; asterisks indicate a significant difference compared with the control (*** P < 0.001; ** P < 0.01; * P < 0.05)Back to article page
