A new method of mixed solid-state fermentation to product protein feed
was established. The wastewater of acetone-butanol fermentation was dried to
20-30 % and then added to the steam-exploded straw or straw residue after
hemicellulose hydrolysis. The method solved the problems of wastewater and
difficulties of evaporation and concentration, achieving the clean production.
