摘      要：Raw materials availability needed for commercial bioethanol production is one of the chal-lenges against its global *** rich,cheap,underused,and readily available starch sources for bioethanol production could help address the ***,this current study inves-tigated the bioconversion of underutilized Artocarpus altilis(breadfruit)starch to bioethanol using Saccharomyces *** effects of the essential fermentation conditions(fermentation time,breadfruit starch hydrolysate(BSH)concentration,pH,and inoculum size)and their interactions on bioethanol production were *** central composite design was used to generate twenty-one experiments conducted under batch fermentation conditions in the *** breadfruit starch hydrolysis led to a BSH concentration of 108.9 g/L under a starch concentration of 122 g/L,microwave output of 720 W,and an incubation time of 6 *** the fermentation of BSH,maximum bioethanol production of 4.99%(V)was reached under the cultivation conditions of BSH concentration of 80 g/L,medium pH of 4.7,inoculum size of 2%(V),and fermentation time of 20.41 *** for pH,the impact of each parameter on the bioethanol production was in this order:BSH concentration,inoculum size,and fermentation *** for the interactions amongst the parameters,the impact is in this order:BSH concentration and inoculum size;BSH concentration and fermentation time;and fermentation time and inoculum *** results of this study indicated breadfruit starch could be hydrolyzed using acid hydrolysis and microwave irradiation in a relatively short *** BSH obtained could potentially add to other substrates for bioethanol production.
