Abstract
For biosurfactant production to be viable, inexpensive raw materials should be used. In this study, substrate, optimization of biosurfactant production by Saccharomyces cerevisiae Optimum conditions were determined as pH 5.69, 10.60% (w/v) molasses and 7.27% (v/v) coco paring meal extract using Box-Behnken design. At these conditions, responses of biomass concentration and emulsification index obtained were 6.43 g/L and 82.81, respectively. Biomass (5.55 g/L) and emulsification index (86.40) was maximum after 3 and 4 days of fermentation respectively. On the other hand, maximum yield for both biomass (6.25 g/L) and emulsification activity (93.33) using a 5-L bioreactor was observed after 4 days of fermentation. The biosurfactant was characterized for its total sugar, protein content and surface tension education.
