Description
Summary:Biological pre‐treatment seems to be promising being an eco‐friendly process, with no inhibitor generated during the process. The potential for elephant grass pre‐treatment with white degradation fungi Pleurotus ostreatus, Agaricus blazei, Lentinula edodes, Pleurotus citrinopileatus, and Pleurotus djamor, in isolated or mixed cultures of these strains, was evaluated. The highest activities of enzymes involved in the degradation of lignocellulosic biomass (laccases, endoglucanases, xylanases, and β‐glucosidases) were observed for A. blazei, L. edodes and the combination of P. ostreatus and A. blazei. In the enzymatic hydrolysis, there was greater release of reducing sugars in the pre‐treated elephant grass samples by A. blazei during 10 days (338.91 ± 7.39 mg g−1 of biomass). For this sample, higher lignin reductions, 24.81 and 57.45%, after 15 and 35 days of incubation, respectively, were also verified. These data indicate the potential of macromycetes such as A. blazei to perform biological pre‐treatments. © 2017 American Institute of Chemical Engineers Biotechnol. Prog., 34:42–50, 2018
