Abstract
The current study is concerned with using environmental wastes as raw materials for bio-ethanol production. The alpha-amylase enzyme has been used to convert the starch molecules of kitchen waste into simple units of glucose which are subsequently fermented into bioethanol. The obtained results showed that 40% substrate and 100 µl of α-amylase were the optimum concentration to produce the highest glucose units at 417.9 and 482.5 milligram/deciliter (mg/dl), respectively. The highest bioethanol production of 423.5 mg/dl was obtained after anaerobic fermentation of free yeast cells at 30oC without shaking. Both bio-ethanol and 25% ethanol were separated by using an amicon cell ultra-filtration system integrated with chitosan or sodium alginate membranes under nitrogen pressure. Each membrane was characterized by Scanning Electron Microscope (SEM) and Ion Exchange Capacity (IEC); while, the hydrophilicity/hydrophobicity was investigated using contact angle. The whole system succeeded to elevate the ethanol concentration in a range of 47-50%, which could be increased with more polymeric modifications
