Fig. 3From: Easy regulation of metabolic flux in Escherichia coli using an endogenous type I-E CRISPR-Cas systemComparison of the regulation effects between low-copy and medium-copy plasmids. Strains were cultured in 50 mL M9 medium containing 1% (v/v) glycerol and 0.2% (g/v) l-arabinose added at 0 h. The error bars indicate the standard deviations of three biological replicatesBack to article page
