主 题：second-generation bioethanol durian seeds alkaline hydrolysis optimization response surface methodology(RSM) Box-Behnken design(BBD) reducing sugar ethanol content
摘 要：As one way to eliminate the issues found in the preceding generation,feedstock exploration in second-generation bioethanol production remains an issue,especially for a tropical country such as *** exotic fruit by-products,durian holds a promising perspective that rests on its abundance,superb carbohydrate content and limited usage until *** work presents the first-ever utilization of durian seeds for sugar production under optimized conditions through alkaline hydrolysis.A simple form of sugar was extracted by varying four parameters,namely substrate loading,NaOH concentration,hydrolysis time and hydrolysis *** surface methodology based on the Box-Behnken design was employed to outline the most optimum parameter *** of variance revealed that the quadratic model fit the data appropriately with the order of significance as substrate loadinghydrolysis timeNaOH concentrationhydrolysis *** optimized conditions for reducing sugar yield,as high as 2.140 g/L,corresponded to50 g/L substrate loading,0.522 M NaOH,60 minutes of hydrolysis time and 80oC hydrolysis *** possible ethanol content of 1.094 g/L was also expected under optimized conditions,demonstrating great potential in second-generation bioethanol production.
