The impact of moisture content on cellulase production.

A solid state fungal fermentation-based strategy for the hydrolysis of wheat straw. Pensupa N, Jin M, Kokolski M, Archer DB, Du C - Bioresour. Technol. (2013) Bottom Line: The addition of yeast extract (0.5% w/v) and minerals significantly improved the cellulase production, to 24.0 ± 1.76 U/g.The hydrolysis of the fermented wheat straw using the fungal culture filtrate or commercial cellulase Ctec2 was performed, resulting in 4.34 and 3.13 g/L glucose respectively.It indicated that the fungal filtrate harvested from the fungal fermentation of wheat straw contained a more suitable enzyme mixture than the commercial cellulase.
