By direct method of isolation, total seven potent yeast isolates were obtained namely CP1, CP2, B2X1, B2X2, BE, GE1 and GE2, which were further screened for their better utility. Out of this, best ethanol producer yeast strain BE was further studied for the optimization of different physical and chemical parameters. Maximum ethanol production obtained at pH-7 while optimum xylose concentration for highest ethanol production was found to be 2%. Best economically viable nitrogen source found to be casamino acid. The same isolate was also found to carry out ethanol fermentation with different sugar source and showed significant results. Effect of various additives like zeolite, cetyl trimethyl ammonium bromide (CTAB) and calcium chloride on the ethanol production was also studied. This isolated BE strain was found to be Candida tropicalis from the morphological, physiological and biochemical characterization. Pilot plant study of this strain with optimized conditions need to be done to make it an industrially suitable strain.
