Full Length Research Paper Improvement of Ethanol Production from Sugarcane Molasses Through Enhanced...

80% of grain alcohol is produced by anaerobic fermentation of discordant sugar sources by Saccharomyces cerevisiae. Yeast alcohol applied science has resulted in vast improvements during the last decade but turn a profit margins were narrowed. Contamination, limited availability of raw materials and fermentation process radiation diagram are the major limitations causing reduced alcohol yields and quality. In view of the importance of alcohol as an alternative for semiliquid fuel, several investigations in ethanol fermentations are currently reported. The cost of the sugar source is an important parameter when considering the overall thriftiness of production and it is of great interests to optimize alcohol yields to ensure an in force(p) utilization of carbon sources (Bai et al., 2008; Carlos et al., 2011).

Another significant factor in fermentation is selecting potent microorganisms with the most ordinarily used microorganisms being yeasts, which can produce ethanol concentrations as high as 18% of the fermentation broth (Balat et al., 2008). Among the yeasts, S. cerevisiae placid remains the prime species for ethanol production.



Previous published reports showed that the ethanol tolerance and sugar utilization efficiency of yeast may be improved by altering the nitrogen sources in fermentation medium (Thomas et al., 1996; Yalçin and Özbas, 2004). Therefore strong economic incentives can be revealed by improving production processes resulting in a substantial growth for the ethanol industry in the near future (Carlos et al., 2011).
Recent studies have focused in the first place on the genetic modification of S. cerevisiae to improve ethanol yields and in effect(p) bioconversion of various substrates to alcohol (Cao et al., 1996) and are limited to agave bagasses with enzymatic hydrolysis, utilizing magneti-cally fluidized bed reactor with immobilized cells and fermentation of molasses by Zymomonas mobilis
