"Lignocellulose Degrading Enzymes from Fungi and Their Industrial Applications"

Abstract

The rich diversity of fungi and diverse range of enzymes produced by them together make researchers to exploit their potential for various industrial applications. Few of the fungal enzymes have already been harnessed and many other are to be explored and brought into use. Recent studies suggested that the lignin degrading fungi can be used in the bioremediation of aromatic hydrocarbons including dioxins, dibenzofuran, aromatic dyes, etc. Employing fungal enzymes for the treatment of pollutants has gained attraction recent days for their selectivity, specificity and eco-friendly nature. Of these enzymes, peroxidases (lignin peroxidase and manganese peroxidase) and laccases are the two major classes of enzymes involved in biodegradation of lignin and recalcitrant xenobiotics. In addition, cellulase and hemicellulase were found to play a role in the management of lignocellulosic wastes. The present review gives a detailed account on the various lignocelluloses degrading enzymes, their fungal sources and their industrial applications.

Endophytes in Lignin Valorization: A Novel Approach

“…These ions which are mainly produced by three pathways—cellobiose dehydrogenase catalyzed reactions, quinone redox cycling, and Fenton reactions catalyzed by glycopeptides ( Dashtban et al, 2010 ), attack the plant cell wall components including lignin governing cleavage of various bonds. It has been observed that post cleavage fragments of lignin are more susceptible to attack by diverse lignin modifying enzymes ( Kantharaj et al, 2017 ). Thus diverse fungi are more efficient in pre-treatment of lignin to their intermediates or low molecular weight heterogeneous compounds (5/6-carbon chains) ( Kumar and Chandra, 2020 ).…”
