<P><I>Ulva rigida</I>, a common green seaweed, was used as a feedstock for the production of bioethanol in a simultaneous saccharification and fermentation (SSF) process carried out under sonication. Sonication provided a faster way for the simultaneous release of glucose from <I>Ulva rigida</I> and its conversion into bioethanol. Within 3 h, 196 ± 2.5 mg glucose per gram of dry weight of biomass and 333.3 ± 4.7 mg bioethanol per gram of glucose were produced in the SSF process under sonication. In addition to being fast, the process was devoid of any chemical pretreatment and involves only a single stage of sonication for the release of glucose from algae by the action of enzymes and also for the simultaneous fermentation of glucose to ethanol using <I>Saccharomyces cerevisiae</I>.</P><BR><BR><P>Graphic Abstract</P><P>The seaweed <I>Ulva rigida</I>, was converted to bioethanol in a simultaneous saccharification and fermentation process carried out rapidly under sonication.<BR><IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c4ra14880k'><BR></P>
