Fig. 2From: Enhancement of D-lactic acid production from a mixed glucose and xylose substrate by the Escherichia coli strain JH15 devoid of the glucose effectFermentative production of D-lactic acid by strain JH13, a 100 g L−1 glucose; b 100 g L−1 xylose; c 100 g L−1 mixture of glucose and xylose. Symbols: filled square, glucose; open square, xylose; filled circle, D-lactic acid. Each data point represents the average of two or more replicates.
