Description
In this research work, waste pineapple (Ananas comosus L.) was used as raw material for the production of bioethanol through direct fermentation by using baker’s yeast (Saccharomyces cerevisiae). Both unsterilized and sterilized fruit pulp were fermented with baker’s yeast (Saccharomyces cerevisiae) under anaerobic condition. Different fermentation conditions such as amount of substrate (100, 200, 300, 400, 500 and 600) g, amount of yeast (0.2, 0.4, 0.6, 0.8, 1.0 and 1.2 % w/w), temperature of fermentation (28, 30, 32, 34, 36 and 38) C, different pH (3.5, 4, 4.5, 5, 5.5 and 6) and period of fermentation (1, 2, 3, 4, 5 and 6) days were carried out to obtain the maximum strength of ethanol. The strength of the resultant bioethanol was measured by sp.gr and also analyzed by gas chromatography (GC). It was pointed out that the maximum strength of bioethanol 49.78 (%v/v) and 46.63 (%v/v) were obtained from sterilized and unsterilized pulp of pineapple respectively.
