In this work, kinetic properties evaluation was made for bioethanol
production from sugar hydrolysate of vegetable waste. The
saccharified sugars were fermented by using Saccharomyces
cerevisiae. The effect of various saccharification factors on sugars
release were studied and observed that the optimized conditions
contributed to 14.4 gL-1of fermentable sugars production. The
produced sugars were subjected to batch fermentation by
Saccharomyces cerevisiae at pH 4.5 and the kinetic parameters of
fermentation were estimated by fitting the experimental data in
modified logistic equations. The data revealed product (ethanol)
yield (YP/S) of 0.39g/g of reducing sugars. Maximum specific growth
rate (μmax), the yield of ethanol on biomass (YP/X) and the yield of
biomass on sugars utilization (YX/S) were determined to be 0.18 h-1,
1.097 g/g and 0.313 g/g, respectively. The process yielded 4.13 gL-1
of ethanol by consumption of 10.6 gL-1 sugars with a volumetric
production rate of 0.0861±0.002 gL-1 h-1
