Figure 2From: Homofermentative production of optically pure L-lactic acid from xylose by genetically engineered Escherichia coli BL-lactic acid fermentation from xylose. A) 70 g L-1 xylose LB medium; B) 100 g L-1 xylose LB medium; C) 70 g L-1 xylose NBS medium. Symbols: open circle, xylose; filled circle, lactic acid; filled square, cell growth; triangle, acetic acid. Each data point is the average of three replicates with the error bar representing the standard deviation.Back to article page
