Solid state fermentation of agricultural wastes for endoglucanase production
2000
Jecu, L.
The lignocellulosic biomass (especially agricultural wastes) is known to be an excellent carbon source for microbial enzyme production. In this paper, the cellulase production from lignocellulosic materials under solid state fermentation (SSF) was investigated. The effects of fermentation conditions, such as moisture content, initial pH, temperature, and composition of mixed substrate (wheat straw and wheat bran) on endoglucanase production by Aspergillus niger 38 were studied. With a moisture content of 74% a pH range of 4.5-5.5 on mixed substrate containing wheat straw:wheat bran of 9:1, 14.80 international units (UI) endoglucanase activity/ml were obtained in 96 h.
