From: Efficient production of polymer-grade L-lactic acid from corn stover hydrolyzate by thermophilic Bacillus sp. strain XZL4

Figure 3

Effects of different nitrogen concentrations on L-lactic acid production by Bacillus sp. XZL4. (A) Reducing sugars consumption. (B) L-lactic acid production. Symbols represent different concentration of peanut meal in the fermentation medium (g L-1): 13.2 (■), 9.9 (●), 6.6 (▲), and 3.3 (▼). The error bars in the figure indicate the standard deviations of three parallel replicates.
