Answer 2

Anaerobic Digestion

Explanation:

    (c)During anaerobic digestion of organic waste,such as the Lignin in    producing bio gas.

1. Lignin is the most significant factor influencing the hydrolysis of the cellulose part in lignocellulosic material.  
2. The underlying debasement step is troublesome in light of the fact that the lignin-starch edifices make an obstruction for microbial change due to the crystalline structure.
3. The lignin is left untreated during the anaerobic processing of natural squanders.  
4. During bio-gas arrangement, processing of cellulose is moderate (rate-restricting) and the majority of the lignin isn't disintegrated. After cellulose lignin is the most bottomless plant polymer.
5. It structures 20 to 30% of the wood of the tree, lignin is a complex polymeric atom, made up of phenyl propanoid units.
