Abstract
The process of enzymatic hydrolysis of cassava bagasse is a potentially effective method of producing biofuel, as cellulase and pectinase are essential for the conversion of biomass. The goal of this work was to compare the hydrolysis effectiveness of cellulase in isolation and in combination with pectinase over a range of time periods (6 and 24 hours). Separately, under controlled conditions, cassava bagasse was used to incubate both cellulase alone and the cellulasepectinase combo. The yield of fermentable sugars was determined by analyzing the resultant hydrolysates, which gave information about how well each combination of enzymes worked. In the first six hours, the yields of cellulase by itself were higher than those of the cellulasepectinase combination. This is explained by the greater starting activity of cellulase in hydrolyzing cellulose, the main ingredient in cassava bagasse. But compared to cellulase alone, the cellulasepectinase combination showed better hydrolysis efficiency over the longer 24-hour period, producing more fermentable sugars. Pectinase was added to help break down pectin barriers, which improved cellulase access to cellulose fibers and eventually raised hydrolysis efficiency. These findings emphasize the significance of reaction time and enzyme synergy in biomass conversion processes. The combination of pectinase and cellulase maximizes the yield of fermentable sugars from cassava bagasse over extended periods of time, despite the fact that cellulase alone may produce larger initial yields. By providing insightful information on how to best utilize enzymatic hydrolysis processes for producing biofuel, this work advances the creation of efficient and sustainable bioenergy technology.
