摘　　要：在单因素试验基础上,通过酸水解糖化澳洲坚果青皮后经发酵制备乙醇,为澳洲坚果青皮找到一种处理的新方式,减少资源的浪费。试验得到的澳洲坚果青皮酸水解的最优组合为A_(1)B_(2)C_(1),即硫酸浓度1%、液固比12︰1(m L/g)、时间60 min,此时水解率为256.073%。澳洲坚果青皮发酵制备乙醇的最优工艺为A_(2)B_(3)C_(3),即接种量40%、发酵时间60 h、磷酸二氢铵添加量0.3%,此时乙醇体积分数为2.912%。Based on the single factor test,prepare ethanol from macadamia nut green peel by acid hydrolysis and fermentation.Finding a new way to process macadamia nut green peel reduces the waste of resources.The results showed that the optimal combination of acid hydrolysis of Macadamia nut green peel was A_(1)B_(2)C_(1),that was sulfuric acid concentration 1%,liquid-solid ratio 12︰1(mL/g),and time 60 min,under which the hydrolysis rate was 256.073%.The optimal fermentation process for ethanol from Macdonia nut green peel was A_(2)B_(3)C_(3),that was the inoculation amount 40%,the fermentation time 60 h,and the addition amount of ammonium dihydrogen phosphate 0.3%,under which the volume fraction of ethanol was 2.912%.
