Enhanced delignification and production of bioactive compounds in wheat straw by optimizing sterilization methods for Irpex lacteus fermentation
Copyright © 2023 Elsevier Ltd. All rights reserved..
This study aimed to examine the effects of sterilization methods on the degradation ability and bioactive compound production of Irpex lacteus in wheat straw. Following 28 days of fermentation, the lignin content of samples autoclaved and pasteurized at pH 4.5 was reduced by 16.0 % - 21.7 % compared to pasteurized samples without pH adjustment, accompanied by a significant increase in sugar yield ranging from 83.30 % - 96.35 %. Autoclaved samples exhibited the lowest total phenol content and antioxidant activity (P < 0.05). Bacillus occupied an absolute advantage (89.1 %) in samples pasteurized at pH 4.5, whereas 10 bacterial genera exhibited abundances above 1 % in pasteurized samples without pH adjustment. Furthermore, 45.1 % - 47.2 % of the metabolites comprised lipids and lipid-like molecules, and some of them were improved by pasteurization at pH 4.5. Overall, pasteurization at acidic conditions is an effective sterilization method for the fungal conversion of wheat straw.
