The Properties of a Series of Isolated Low Molecular Weight Peptides from Phanerochete Chrysosporium in Decomposition of Lignin

摘要

Lignin is known as one of the most recalcitrant biomaterials on earth. Previous studies indicated that lignin biodegradation can not be accomplished efficiently only by the ligninolytic enzymes. Wood-rotfungi might employ some small, diffusible active agents to initiate the breakdown of lignin. Some glycopeptides (1-5kDa) had been partially purified from Phanerochaete chrysosporium, which could catalyze a redox reaction between electron donors and O_2, to produce hydroxyl radical and reduce Fe3+ to Fe~(2+). But there was no report on further purification and function of these glycopeptides in lignin degradation.
