| Abstract: | This study presents degradation enhancement of pine needles by Aspergillus niger F7, isolated from soil. A modified alkali pretreatment [NaOH+H2O2 (1M); ratio, 9:1] is found the best among all methods when needles are soaked in this solution for 2 h followed by thorough washing with tap water. Degradation of pine biomass was measured in terms of enzyme (cellulase & xylanase) production, biodegradation index (BI) and hydrolysis (%). There are high enzyme units, BI and hydrolysis (%) in pretreated material as compared to untreated one. |
