Figure 4From: Efficient production of polymer-grade L-lactic acid from corn stover hydrolyzate by thermophilic Bacillus sp. strain XZL4Batch fermentations from corn stover hydrolyzate by Bacillus sp. XZL4. Symbols represent carbohydrates consumption and cell growth in the fermentation medium (g L-1): Reducing sugars consumption (■), L-lactic acid production (●), and Cell growth (◆). The error bars in the figure indicate the standard deviations of three parallel replicates.Back to article page
