The effect of sugar concentration and temperature on growth and volatile phenol...

The wine spoilage yeast Dekkera bruxellensis was evaluated for the production of 4-ethylphenol under low concentrations (0.02–20 g L 1) of glucose and fructose in synthetic media. Measurable amounts of 4-ethylphenol were produced over 0.2 g L 1 of each sugar. The yeast growth rate and amount of biomass formed increased from 0.2 to 20 g L 1 of glucose or fructose, being accompanied by increasing production of 4-...
