Fresh pineapple juice was inoculated with 8 preselected yeast strains and incubated for high yield ethanol production at between 25℃ and 35℃.The natural pH of the juice did not affect the growth of the strains or the alcohol yields. The higher ethanol concentrations were obtained at 30℃ and 35℃ in the ranges of 27.17 to 46.50 g/l and 31.38 to 54.65 g/l, respectively, with 82% and 89% as the highest yields when referring to the theoretical yield.The study indicated that strain CMl is the best performing strain at 30℃ and 35℃ according to yield and productivity.
