The effect of water-soluble compounds from ammonia fiber explosion (AFEX)-treated corn stover on (A) cell growth, (B) percent glucose consumption and (C) percent xylose consumption after 24 h fermentation. The experiments were conducted in 24 wells plate at 2.0 mL working volume under largely anaerobic condition. The initial concentration of glucose, xylose and cell density was 3 g/L, 20 g/L and 0.5 unit of OD600 nm, respectively. The fermentation media was supplemented with 2.5 g/L yeast extract and 5 g/L peptone.
