ABSTRACT

Groundnut (Arachis Hypogaea) shell and carpet grass (Axonopus flexuosus) were assessed for bioethanol production using dilute acid hydrolysis (10 %, 15 % and 20 % H2SO4) and fermentation using yeast (saccharomyces cerevisiae). The percentage yields were determined to be 27.15 %, 19.69 % and 8.79 % for groundnut shell and 22.69 %, 13.92 % and 7.69 % for carpet grass respectively. The densities of the bioethanol produced were calculated to be 0.8072 g/cm3 for groundnut shell and 0.8303 g/cm3 for carpet grass respectively. The proximate analysis result of the groundnut shell and carpet grass were observed to be 84.74±0.81 and 81.16±2.63 percentage carbohydrate, this may be the reason why groundnut shell produced higher yield of bioethanol than carpet grass. Thus, groundnut shell and carpet grass have good potential  as sources of raw materials for bioethanol production.
