001			IA_Ethanol production from pineapple waste juice batch fermentation (Ananas comosus L.) by the bacteria Zymomonas mobilis with and without controlling pH, and by the yeast Saccharomyces cerevisiae without controlling pH was studied. Respose variables were ethanol (%), total sugars (%), titratable acidity (%) and pH. A randomized complete design was used. Highest ethanol production was obtained by Z. mobilis without controlling pH (6.3 %), comparing with Z. mobilis with controlling pH (4.92%) and with S. cerevisiae without controlling pH (5.41%). Optimum conditions to produce ethanol with Z. mobilis were: temperature 30ºC, approximately 11% total sugars, about 0.3% titratable acidity and pH of about 5.5. The optimum conditions to produce ethanol from S. cerevisiae were: temperature 30ºC, about 10% total sugar, approximately 1% titratable acidity and pH of about 3.4.
