Abstract

In this study, repeated-batch fermentations in a biofilm reactor were evaluated for ethanol production from non-sterile enriched (NSE) and non-sterile non-enriched (NSNE) carob extracts by using Saccharomyces cerevisiae. For the NSE medium, the ethanol production (P) and yield (YP/S) were 18.46 g/L and 33.76%, respectively. However, for the NSNE medium, P and YP/S were 19.57 g/L and 38.14%, respectively. Results indicated that cost-effective ethanol production from non-sterile carob extract (NSCE) can be successfully applied in a biofilm reactor regarding both energy cost and recovery time.
