Comparison studies on biological pulping of lignocellulosic agro-residue using Tremetes versicolor and Lentinus crinitus

摘要

A comparison is made for the performance of the two white-rot fungus Tremetes versicolor and Lentinus crinitus for lignin biodegradation of the lignocellulosic agro- residue jute stick with amendment glucose as carbon source and I- alanine as nitronen source respectively. The bioprocess parameters are optimized for jutestick. The highest lignin biodegradation was observed with Tremetes versicolor and Lentinus crinitus were 64.35% (w/w) and 62.85% (w/w) of jute stick with optimum doses respectively. The optimum time of lignin biodegradation was 12 days for both Tremetes versicolor and Lentinus crinitus respectively. The optimum temperature of lignin biodegradation was 40℃ and the optimum pH of lignin biodegradation was 4.5 respectively. 30%(v/v) and 7 days age-old innoculum culture was used for the bioprocess studies. The optimization of bioprocess governing parameters shows an increase of lignin biodegradation of the lignocellulosic jute stick.
