Effects of inoculation OD (A and B), nutrients (C and D), initial pH (E and F), and pre-hydrolysis time (G and H) on cell viability (colony forming unit) in simultaneous saccharification and fermentation of washed steam-exploded corn stover (A, C, E, and G) and whole slurry (B, D, F, and H). CFU, colony forming unit; N, nutrients; OD, optical density; P.T., pre-hydrolysis time; SECS, steam-exploded corn stover; WS, Whole slurry.
