The need to diversify energy sources and to change from the present non‐renewable hydrocarbon sources to renewable energy sources has prompted huge investments in research activities to produce bioethanol from carbohydrate‐rich foodstuffs such as cassava tuber, sugarcane molasses, yam tubers, rice grains, corn grains, and a host of others. In recent times, however, more attention has been given to producing bioethanol from the non‐edible parts of carbohydrate‐rich foodstuffs, which are obtained mainly as waste products from food‐crop processing. Such non‐edible components include peels, bagasse, straw, stalk, and cobs. The most important component of the biomass is lignocellulose, which is broken down into carbohydrates and then fermented. The major challenge in deploying biomass as feedstock for bioethanol production is the fact that lignocellulosic biomass is highly recalcitrant and therefore requires more vigorous pretreatment prior to saccharification and fermentation. The main techniques used for pretreating lignocellulosic materials are physical and thermal as well as chemical and biological methods. In Nigeria, lignocellulosic bioethanol production potential from agricultural residues amounts to about 7.556 × 109 L per annum with more than 62% generated from process residues. Cassava biomass alone can produce more than 114 L of bioethanol for every ton of cassava peels after processing. Nigeria has more than enough agricultural residues for bioethanol production to meet its sustainable bioethanol‐blending demands. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…Pretreated lignocellulosic was scarified enzymatically to get fermentable sugars and Aspergillus niger was incubated directly into four sets of the mixture and the fifth set served as the control. These sets up were kept at room temperature (28 o C) and shaken at intervals of five days to produce homogenous solution after which the mixture were filtered using filtered paper [13].…”

Ethanol is an alternative fuel derived from renewable biological resources. It's a good substitute for gasoline in spark ignition engines. In this study, the sugar cane bagasse was chemically pretreated with 1% NaOH at room temperature for 2 hours. Dilute acid H 2 SO 4 and Aspergillus niger was used to hydrolyse the biomass to sucrose. Fermentation of the hydrolysed sample was done using Saccharomyces cerevisiae. The fermented product was purified by distillation process at 78 o C, and the fraction was collected, and the ethanol was determined by measuring the specific gravity. The production of ethanol from sugar cane bagasse with Saccharomyces cerevisiae was determined after the inoculation into sample A 1 , A 2 and B 1 and B 2 and highest ethanol produced were from B 1 with 0.090 followed B 2 0.074, A 2 with 0.069% and D 0.116. The use of Saccharomyces cerevisiae gives a better yield. The result of this study can be of a better application in the large production of biofuel from sugar cane bagasse which is renewable and highly abundant, it is saving costs by Original Research Article

“…Furthermore, ethanol serves as a major raw material for biomedical and pharmaceutical companies. The demand for ethanol has increased steadily over the last century as the world's population has grown and more countries have become industrialized [7]. There is a great interest in exploring alternative sources of producing ethanol.…”

Plant biomass can be utilized to produce bioethanol, because they are abundantly available in nature. The cost of ethanol production from lignocellulosic materials is relatively high with low yield. But this can be solved by strain improvement processes. This study is aimed at evaluate bioethanol production potential of improved strains of Saccharomyces cerevisiae developed through random mutagenesis. Bagasse was hydrolysed with 1% NaOH and 1.0M H2SO4 respectively for five days. The hydrolysed bagasse was saccharified using Aspergillus niger isolated from soil samples. Saccharomyces cerevisiae isolated from locally produced wines; sorghum (burukutu) oil palm wine (emu) and raphia palm wine (oguro) with the highest ethanol production (5.0g/ml) were used, and then treated with physical mutagen (ultraviolet light) and chemical mutagens (Acridine dye, Bromo acetaldehyde, dithiothreitol, Ketoconazole and Nitrous acid) respectively to develop mutant with high ethanol producing efficiency under varied operational parameters. Three mutant strains of Saccharomyces cerevisiae namely;- SUV, SCD and SCK produced higher volumes of ethanol (7.5 g/ml, 9.8 g/ml, 11.2 g/ml respectively). SCD and SCK were able to grow at 25% ethanol concentration indicating that they had higher ethanol tolerance ability than the other strains. The optimum temperature and pH for ethanol production by all the strains were 350C and 6.0 respectively. The improved strains of Saccharomyces cerevisiae developed through random mutation techniques had produced more ethanol from the bagasse than the wild-type.
