Aerobic And Anaerobic Conditions

Isoamyl acetate is a natural flavour ester, widely used as a source of banana flavour by the food industry.Williopsis saturnusvar.saturnusis a yeast which can produce isoamyl acetate by esterification of amyl alcohols with acetyl coenzyme A via fermentation. The evaluation of this kind of production as an alternative way to obtain natural banana flavour could be possible, if the levels produced were high enough to make a commercial product. In this study, the effects of temperature (15°C and 25°C) and aeration (aerobic, semiaerobic, and anaerobic) on the production of isoamyl acetate byWilliopsis saturnusvar.saturnusfrom sugar beet molasses were examined. According to the results obtained, isoamyl acetate production rate and specific productivity were higher at 25°C than at 15°C and at semiaerobic condition than aerobic and anaerobic conditions.Williopsis saturnusvar.saturnusshowed a production rate of 0.703 mg L−1 h−1and a specific productivity of 0.0297 mg L−1 cell−1 h−1isoamyl acetate with semiaerobic condition at 25°C. The maximum amount of isoamyl acetate reached with these conditions was 118 mg/L.
