Introduction In the future, the use of plant biomass as a feedstock for chemical synthesis may become more widespread. Approximately 95% of plant biomass is composed of lignocellulosic material. Lignocellulose typically contains 50% cellulose, 25% hemicellulose and 25% lignin. Lignin is a stereoirregular polymer that protects cellulose and hemicellulose from enzymatic hydrolysis. Microorganisms...

Phanerochaete chrysosporium BKM-1767 secretes multiple lignin peroxidase isoenzymes when grown under nitrogen-limited conditions. Here we report the purification of these heme-containing peroxidases, and their physical and catalytic charaterization. Ten hemeproteins, designed H1-H10, were separated by anion exchange HPLC. Six of them, H1, H2, H6, H7, H8, and H10, were lignin peroxidases, oxidiz...

Aspergillus niger ( A. ) and Penicillium chrysogenum P. can significantly promote the degradation of maize straw phosphorus release. Compared with , is more efficient in releasing. After seven days incubation, highest ratio content +maize treatment 2.58% 2.3 mg/L, respectively. The mechanisms for decomposition between these two fungi are different. Oxalic acid primary organic secreted by which ...

Most pears in Anhui Province are a kind of self-incompatible fruit whose quality is strongly influenced by the male pollen. The proteomic variation of Dangshan Su pollinated by different varieties was analysed using the isobaric tag for relative and absolute quantitation (iTRAQ) to investigate the effect of pollination by different varieties on the pear lignin pathway. Among the 3980 proteins i...

Lignocellulosic biomass is an organic matrix composed of cellulose, hemicellulose, and lignin. In nature, lignin degradation by basidiomycetes the key step in lignocellulose decay. The white-rot fungus Phanerochaete sordida YK-624 (YK-624) has been extensively studied due to its high ability. It was demonstrated that can secrete peroxidase manganese for degradation. However, underlying mechanis...
