Lignin

Vedclass · Answer

(D) During the process of anaerobic digestion for biogas production,methanogenic bacteria break down complex organic matter like cellulose,hemicellulose,and lipids into methane $(CH_4)$,carbon dioxide $(CO_2)$,and hydrogen $(H_2)$. Lignin is a complex phenolic polymer found in the cell walls of plants. Due to its highly complex and recalcitrant structure,it is resistant to microbial degradation under anaerobic conditions. Therefore,lignin remains undegraded in the biogas digester.

In the anaerobic digestion of organic waste,such as in the production of biogas,which of the following remains undegraded?
