Fig. 6From: Development and optimization of a microbial co-culture system for heterologous indigo biosynthesisThe indigo bioproduction by the co-cultures containing the rpoA mutants. A The statistical analysis of the biosynthesis performance difference between the co-culture variants grown in 96-well plate. B Comparison of the indigo production by the top five co-culture variants. The upstream and downstream strains were inoculated at 1:1 ratio. The error bars represent the standard error of at least three biological replicatesBack to article page
