Kinetic modeling of Candida shehatae ATCC 22984 on xylose and glucose for ethanol production

© 2017 Taylor & Francis. Candida shehatae ATCC 22984, a xylose-fermenting yeast, showed an ability to produce ethanol in both glucose and xylose medium. Maximum ethanol produced by the yeast was 48.8 g/L in xylose and 52.6 g/L in glucose medium with ethanol yields that varied between 0.3 and 0...
