ABSTRACT
Effect of various Physico-Chemical and Nutritionalparameter for the production of ethanol from mahua flowerusing Saccharomyces cerevisiae -3090 through submergedfermentation have been studied. Substrate mahua flowercontains 68% Total sugar. Yeast strain S.cerevisiae-3090was obtained from National Collection of IndustrialMicroorganisms (NCIM), Pune, South India. Maximumproduction of ethanol obtained at different optimizedparameters such as substrate concentration at 28%, pH at5.0, Inoculum level at 2%, Inoculum age at 48 hours,Temperature 300c, Urea at 0.06 %, Copper sulphate 3 ppm,Sodium Potassium Tartrate 1.0 g/l and fermentation periodis 48 hours is 13.450%(w/v). Effect of Sodium PotassiumTartrate and Urea showed the maximum production ofethanol. It is also conformed that the designed media issuitable for ethanol yield for large scale production.
