Highlights
Present study focuses on exploitation of date waste as a source for bioethanol production from the fermentable sugars released due to different chemical and biological
It was observed that pretreated waste date can be economically utilized as a cheaper substrate for bioethanol production considered as a viable alternative fuel to solve both energy and environmental crises
As part of our study of cost effective means of producing fuels from biomass, we report a process for ethanol producing from lignocellulosics prehydrolysed by alkali followed by saccharification carried by co-cultivation of A. awamori and A. niger and fermentation of the released fermentable sugars to bioethanol, using a yeast strain Saccharomyces cerevisiae KD2 in five liter capacity bioreactor designed for ethanol production. certain fermentation parameters such as substrate concentration, optimum pH, temperature, time, playing important roles in obtaining good ethanol yield had been optimized
