Abstract
Evaluation of Lysinibacillus SP, isolated from Coptotermes curvignathus Gut, for the delignification of oil palm residues
Highlights
The pulp and paper industry is one of the high demand sectors, resulting from the accelerating demands for paper-based products
Screening and identification of lignin degrading bacteria The bacterial strain was selected based on the ability to grow on mineral salt medium supplemented with kraft lignin as sole carbon source, as well as the ability to decolorise industrial dyes evident by the formation of zone of clearance around the plates
In this study we investigated the ability of Lysinibacillus sp isolated from termite gut in degrading the lignin component of oil palm residues
Summary
The pulp and paper industry is one of the high demand sectors, resulting from the accelerating demands for paper-based products. The removal of lignin is one of the key processes in paper production as it imparts stiffness on mechanical pulp fibres and yellow coloration on newsprints (PALIWAL et al, 2012). Conventional methods of dissolving lignin in wood involve the use of chemicals and bleaching agents (LIEW et al, 2011; AYERONFE et al, 2018). These processes do require high inputs of energy and produce highly toxic effluents which are not environmental friendly (SUMATHI; HUNG, 2006). The continuous increase in demand for paper products and growing environmental concerns necessitate the need to look towards technological improvement in the conventional pulping methods
