This study aimed at evaluating the fermentative performance of Saccharomyces cerevisiae isolated from palm wine on honey slurry and dates palm fruit juice blend for wine production. The yeast was isolated from palm wine on saboraud dextrose agar (SDA) using pour plate technique and was identified using microscopic and standard biochemical techniques. Physicochemical parameters were determined during 21 days fermentation using standard procedures. The proximate composition of the blend before fermentation and the produced wine was evaluated. The microbiological and sensory evaluations of the produced wine was investigated. The yeast strain was identified as Saccharomyces cerevisiae. The fermentation recorded total viable yeast count from 2.5x10 6 to 13.0 x 10 6 CFU/mL. The physicochemical parameters revealed that during the fermentation, the pH values ranged from 4.3 to 5.4, percentage titratable acidity (TTA) ranged from 5.2 to 9.4. The temperature of the fermentation ranged from 24 to 29°C and the specific gravity values decreased steadily from 1.100 to1.010. Proximate composition of the date fruit revealed low protein content between 1.00 and 1.05, but high moisture content (82.43%). The produced wine contained reasonable amount of total carbohydrate A (19.59%), B (25.28%), C (22.7%) and D (21.88%). There were variations on other proximate compositions observed. The produced wine was not contaminated with bacteria and fungi. Sensory evaluation of the wine revealed acceptable aroma/flavor and taste. This study indicates that Saccharomyces cerevisiae strain from the palm wine have good fermentative performance which suggested that it could be used for fruit wine production and other industrial applications preceded by further experiments.
