Abstract
Rejected Papaya (Carica papaya L.) and Pineapple (Ananas comosus L.) were considered as sources of sugary material for the preparation of bioethanol. Direct fermentation of rejected and sterilized pulp was carried out by using baker's yeast (Saccharomyce cerevisiae) under anaerobic conditions. Different fermentation conditions such as amount of substrate such as (100, 200, 300, 400, 500 and 600) g, amount of yeast such as (0.2, 0.4, 0.6, 0.8, 1.0 and 1.2) % (w/w), temperature of fermentation such as(28, 30, 32, 34, 36 and 38) 'C and different pH such as (3.5, 4, 4.5, 5, 5.5 and 6), period of fermentation (1,2,3,4,5 and 6 ) days were employed during fermentation. The strength of the resulting bioethanol was analyzed by using gas chromatography (GC). It was pointed out that the maximum strength of bioethanol 20.154 % (v/v) was obtained from sterilized pulp of papaya and 85.276% (v/v) from sterilized pulp of pineapple respectively.
