摘要

Solid-state fermentation obtained from different and low-cost carbon sources was evaluated to endo-cellulases and endoxylanases production by Aspergillus japonicus C03. Regarding the enzymatic production the highest levels were observed at 30 ℃, using soy bran added to crushed corncob or wheat bran added to sugarcane bagasse, humidified with salt solutions, and incubated for 3 days (xylanase) or 6 days (cellulase) with 70% relative humidity. Peptone improved the xylanase and cellulase activities in 12 and 29%, respectively. The optimum temperature corresponded to 60 ℃ and 50-55 ℃ for xylanase and cellulase, respectively, both having 4.0 as optimum pH. Xylanase was fully stable up to 40 ℃, which is close to the rumen temperature. The enzymes were stable in pH 4.0-7.0. Cu~(++) and Mn~(++) increased xylanase and cellulase activities by 10 and 64%, respectively. A. japonicus C03 xylanase was greatly stable in goat rumen fluid for 4 h during in vivo and in vitro experiments.
