Abstract:
... CAZymes play a very important role in the biotransformation of corn stalk biomass, which is an important resource for sustainable development. Pleurotus djamor can produce CAZymes related to the decomposition of corn stalk lignocellulose biomass in sole corn stalk substrate; however, little is known about their encoding genes. In order to identify CAZymes encoding genes, RNA high-throughput sequen ...

Abstract:
... In this work, the deconstruction mechanism of corn stover cell wall polymers during ball milling was evaluated. The characterization showed that ball milling not only brought about the dissociation of the cross-linked cellulose-hemicellulose-lignin complex but also led to the depolymerization of the cell-wall polymers especially the carbohydrates. Micromorphology characterization revealed that mec ...
