Abstract

Addition of different carbon compounds at the onset of the ripening phase of growth, during the fed-batch fermentation of molasses for baker's yeast production, enhanced not only the yield and activity but also the reserve carbohydrates of both wet yeast (WY) and active dry yeast (ADY). Among the carbon sources, sucrose(l%), maltose(l%), trehalose(0.5%) and lecithin(0.5) marginally increased the biomass, but significantly increased the fermenting ability and viability of both WY and ADY. Significant increase in trehalose (from 4.0% to 9.4%) and marginal increase in glucan and mannan of ADY with these carbon sources indicate the availability of suitable precursors or intermediates for their synthesis.
