Fig. 6From: Adaptive laboratory evolution and shuffling of Escherichia coli to enhance its tolerance and production of astaxanthinEffect of CRISPRa of genes on the production of astaxanthin in E. coli AST-4. E. coli AST-4 harboring pBbB2K-dCas9*-MCPSoxS and pTargetA-X was set as the control. The data represent the means of three replicates, and error bars indicate standard deviationsBack to article page
