Abstract
Effective pretreatment of lignocellulosic biomass is required to improve cellulose accessibility and enhance enzymatic hydrolysis. In this study, Enset fiber was subjected to different pretreatments to increase the glucose yield from enzymatic hydrolysis. Firstly, the effect of milling time, rotational speed, and milling mode in planetary ball milling were studied. Secondly, the intensification effect of combining planetary ball milling with low concentration alkaline pretreatment in sequential and simultaneous (dry chemomechanical) schemes were investigated. Following pretreatment, samples were hydrolyzed using cellulase and their crystallinity; particle size and morphology were analyzed. The result confirmed that the maximum glucose yield achieved from the dry chemomechanical method was 581 g/kg of pretreated Enset fiber, which is 86 and 22% higher compared to single alkaline and single dry ball milling pretreatments, respectively. Compared to the sequential pretreatments, the dry chemomechanical pretreatment resulted in comparable glucose yield from hydrolysis while cutting the pretreatment time from 120 to 90 min. Moreover, the energy efficiency of dry chemomechanical pretreatment was 1.3, 5.3, and 7.8 times higher than the energy efficiency of dry ball milling, sequential, and alkaline pretreatments, respectively. Therefore, the action of alkali and planetary ball milling in the dry chemomechanical pretreatment acted synergistically to intensify the pretreatment and enhance the production of glucose.
