摘要：

Agricultural residues are the low-cost lignocellulosic materials that have potential to employ as the substrate for enzyme production under solid-state fermentation. Total eight solid substrates were examined for enzyme production; wheat bran was found to induce maximum endoglucanase (26.33 IU/gds), FPase (2.11 IU/gds) and beta-glucosidase (34.30 IU/gds by Aspergillus niger NFCCI 4113). After optimization of cultural parameters, Aspergillus niger NFCCI 4113 was found to produce maximum endoglucanase (55.26 IU/gds), FPase (4.64 IU/gds), xylanase (1175.76 IU/gds) and beta-glucosidase (71.30 IU/gds) at temperature (30 degrees C), incubation time (6 th day), pH (7.0) and moisture content (70%), using peptone (1.0%, w/v) as the nitrogen source and Tween-80 (0.10%, w/v) as the surfactant.
