Résumé
The present work studied the fermentative potential and carbon metabolism of an indigenous yeast isolated from Lebanese apples for cider production. The indigenous yeast strain was isolated from a spontaneous fermented juice of the Lebanese apple variety 'Ace spur'. The sequencing of the Internal Transcribed Spacer (ITS) domain of rRNA identified the isolated yeast strain as a member of the Hanseniaspora genus. These results suggest an intragenomic ITS sequence heterogeneity in the isolated yeast strain specifically in its ITS1 domain. The different investigations on the yeast carbon metabolism revealed that the isolated yeast is 'Crabtree positive' and can produce and accumulate ethanol from the first hours of fermentation. Thus, our findings highlight the possibility of using the isolated indigenous Hanseniaspora strain as a sole fermentative agent during cider production.
