Lignin Degradation Problem

Lignin is a high molecular weight compound of phenolic groups. The bacteria even having there enzymatic activity towards lignin, is also not capable to degrade lignin so much efficiently.The main region behind it is that, the black liquor of paper industries contain some toxic substance like Dioxne,chlorolignin compounds etc.
It is not easy to bacteria survive in such harsh condition.So the degradation process become low.

Try This for Increasing Degradation of Lignin :

1.Add HgSO4 before going for inoculation of bacteria in black liquor.
2.First acclimatize the bacteria before addition.
