Figure 3: Changes of intracellular metabolites in amino acids metabolism in K. vulgare-B. thuringiensis consortium.

The mutation of amidohydrolase in K150 and amino acid permease in B150 influence the amino acids metabolism, and tricarboxylic acid cycle in B150 was improved significantly. The y-axis was the relative abundance, being calculated by normalization of peak area of each metabolite to internal standard and dry weight of cells. Each value represented mean value of four replicates, and the error bars showed the standard deviations.
