Bioethanol has been a focus of researchers as alternate green fuel. Agro residues could be a promising resource for bioechanol production. In this study, we explored the potential of these fruit wastes to produce total reducing sugars (TRS), pentose sugars (PS) and bioethanol.. For this purpose, fruit wastes (pineapple, cashew fruit and plantain peels) were taken as a substrate with the use of microorganism Saccharomyces cerevisiae. The conversion of fruits wastes were carried out via acid hydrolysis, which yielded fermentable sugar. The results showed that the ethanol production rate through fermentation of fruit waste yields was optimal at pH 5.5, temperature 32°C, specific gravity 0.865 and a concentration of about 6.10%. For viability of producing ethanol in large quantities and reasonable costs, we did optimization of various physicochemical parameters viz. pH, temperature and specific gravity. The waste materials after fermentation serve as soil fertilizer.

利用当地果渣生产生物乙醇及其优化

生物乙醇作为替代绿色燃料一直是研究人员关注的焦点。农业残留物可能是生产生物乙醇的有前途的资源。在这项研究中，我们探索了这些果渣产生总还原糖（TRS），戊糖（PS）和生物乙醇的潜力。为此，以果渣（菠萝，腰果和车前草皮）为基质使用微生物酿酒酵母。水果废料的转化是通过酸水解进行的，产生了可发酵的糖。结果表明，在pH 5.5，温度32°C，比重0.865和浓度约6.10％的条件下，通过果渣发酵产生的乙醇生产率最佳。为了大量生产乙醇的可行性和合理的成本，我们对各种理化参数进行了优化。pH，温度和比重。发酵后的废料用作土壤肥料。
