Production of 1,3-propanediol from glycerol via fermentation by Saccharomyces cerevisiae

Baker's yeast,Saccharomyces cerevisiae, is reported as possessing the ability to convert glycerol to 1,3-propanediol. Various fermentation conditions were tested at different temperatures. Under anaerobic fermentation at 25 °C, 93.6 wt% glycerol was consumed, yielding 42.3 wt% 1,3-propanediol.
