medium with these inhibitors would strongly affect the cell
activity and
fermentation performance.
The inhibitors in sugarcane bagasse hydrolysate generated from GVL/water solution were analyzed (Table 3).
Results showed that all the evaluated inhibitors were at a low level.
Formic acid, levulinic acid, furfural and HMF only reached 0.07, 0.58, 0.04 and 0.42 g/L, respectively.
The TPC in hydrolysate are potent inhibitors during ABE fermentation.
