From: Controlling microbial contamination during hydrolysis of AFEX-pretreated corn stover and switchgrass: effects on hydrolysate composition, microbial response and fermentation

Fig. 1

Concentrations of lactate and glucose in different batches of ACSH and ASGH produced from different years of corn stover and switchgrass: a by the NAC method in the presence of gentamicin and b by the AC method. Each bar represents an individual batch of hydrolysate. An arrow indicates a higher lactate and lower glucose concentration in the hydrolysate compared with other batches of hydrolysate produced from the same feedstock. Because of lactate production, all batches of hydrolysate produced from 2010 CS showed a lower level of glucose than other ACSH produced using the NAC method
