Figure 1

Effects of corn stover hydrolyzate concentrations on L-lactic acid production by Bacillus sp. XZL4. (A) The total reducing sugars consumption. (B) Glucose and xylose consumption. (C) L-lactic acid production. (D) Cell growth. Symbols represent different initial concentrations of total reducing sugars of corn stover hydrolysis (g L-1): 133 (■), 83 (), 53 (▲), and 41 (). The symbols for xylose consumption under different initial concentrations of total reducing sugars of corn stover hydrolysis (g L-1) were 133 (□), 83 (), 53 (), and 41 (), respectively. The error bars in the figure indicate the standard deviations of three parallel replicates.
