Lignin contains polymers made up of 500 to 600 units that has a very branched, amorphous composition, connected to cellulose, hemicellulose and pectin in plant mobile walls. Lignin undergoes quite sluggish decomposition, mainly by white rot fungi and actinomycetes; its 50 %-daily life below temperate conditions is about 6 months.[188] https://teresal788nfw8.wikigdia.com/user
