Present investigation explores the use of pineapple peel, a food industry waste, for acetone-butanol-ethanol (ABE) production using Clostridium acetobutylicum B 527. Proximate analysis of pineapple peel shows that it contains 35% cellulose, 19% hemicellulose, and 16% lignin on dry basis. Drying experiments on pineapple peel waste were carried out in the temperature range of 60-120°C and experimental drying data was modeled using moisture diffusion control model to study its effect on ABE production. The production of ABE was further accomplished via acid hydrolysis, detoxification, and fermentation process. Maximum total sugar release obtained by using acid hydrolysis was 97g/L with 95-97% and 10-50% removal of phenolics and acetic acid, respectively during detoxification process. The maximum ABE titer obtained was 5.23g/L with 55.6% substrate consumption when samples dried at 120°C were used as a substrate (after detoxification).
本研究探索了利用菠萝皮（一种食品工业废料），通过丙酮丁醇乙醇（ABE）生产使用丙酮丁醇梭菌 B 527。菠萝皮的近似分析表明，其干物质中含有 35%纤维素、19%半纤维素和 16%木质素。在 60-120°C 的温度范围内对菠萝皮废料进行了干燥实验，并使用水分扩散控制模型对实验干燥数据进行建模，以研究其对 ABE 生产的影响。ABE 的生产是通过酸水解、解毒和发酵过程完成的。使用酸水解法获得的最大总糖释放量为 97g/L，在解毒过程中，酚类和乙酸的去除率分别为 95-97%和 10-50%。当使用 120°C 干燥的样品作为（解毒后）底物时，最大 ABE 得率为 5.23g/L，底物消耗率为 55.6%。
