Production Of Bioethanol From Elephant Grass (pennisetum Purpureum) Stem

The production of bio-ethanol from Elephant grass (Pennisetun purpureum) stem was carried out using elephant grass stem as a feedstock and a combination of Aspergillus niger at 0.2%(w/v) 0.4%(w/v), 0.6%(w/v), 0.8%(w/v) and 1%(w/v) concentrations and Saccharomyces cerevisiae (brewer’s yeast) at 0.5% (w/v), 1%(w/v), 1.5%(w/v), 2%(w/v)and 2.5%(w/v) concentrations as cells by simultaneous saccharification and fermentation (SSF). The study determined the most suitable pre-treatment method from the following pretreatment methods; 1M H2SO4, 0.1M H2SO4, 1M NaOH, 0.2M NaOH, Boiling, and 3M NH4OH. IM N…
