Fig. 4From: Promotion of compound K production in Saccharomyces cerevisiae by glycerolComparison of fermentation process between YPD and 20% glycerol medium. a Alterations in production during fermentation. b Other parameters altered during fermentation. In the legend, 1 represents YPD, and 2 represents YPDG (20%) (20% of glucose in YPD is replaced by an equimolar carbon quantity of glycerol). OD254 represents the relative quantity of UDPGBack to article page
