Banana raw peel, banana ripe peel and banana pseudostem feed stocks were utilized for bioethanol production. The results of characterization of feed stocks showed maximum values of sugars in banana ripe peel. It showed 21.98% total reducing sugar, 12.05% non-reducing sugars, 10.89% glucose content, 7.44% fructose content, 2.72% xylose and 3.38% sucrose contents.
Banana pseudostem exhibited a high cellulose content of 25.57% and lignin content of 15.44% whereas the hemicellulose content was found to be maximum in banana raw peel with 27.14%.
Among the pre-treatments carried out, acid treatment was observed as the best treatment compared to alkali treatment. Acid treatment was noticed to have maximum increase in total reducing sugar content of banana raw peel (12.00%). The percent increase in non-reducing sugar was found to be highest in acid treated banana pseudostem (4.11%). Also the lignin removal percentage was observed to be high in acid treated banana pseudostem (25.92%).
Saccharomyces cerevisiae produced 6.63% of ethanol from untreated samples of banana raw peel. However Zymomonas mobilis was able to produce only 3.11% of ethanol from acid treated samples of banana ripe peel. From the results, it was inferred that the banana raw peel has the maximum potential to be used as feedstock for ethanol production. Saccharomyces cerevisiae was noticed to be the best microorganism.
A cellulolytic microorganism was isolated from the degraded samples of banana. The organism was characterised and it was found to be closely related to
bacterial species Nesterenkonia sp. EGI 80099. Mixed cultures of this microorganism and Saccharomyces cerevisiae produced a maximum percentage of 6.88% ethanol from banana raw peel in single batch bioconversion.
