摘要

木质素和构成这种聚合物的单酚类物质促进了缺氧生态系统中甲烷的产生，估计占泥炭地甲烷排放量的1.2-14.2%。甲氧基可由产甲烷菌直接转化为甲烷。因此，由于灌木入侵而增加的木质素输入泥炭地将释放比以前认为的更多的甲烷。

Lignin is an overlooked methane source in anoxic ecosystems

Lignin and the monophenols that constitute this polymer promote methane production in anoxic ecosystems, contributing an estimated 1.2–14.2% of methane emissions in peatland. The methoxy group can be directly converted to methane by methanogens. Consequently, increased lignin input to peatland from shrub encroachment would release more methane than previously thought.
