Abstract

Xylitol is a fermentation product of xylose which can be used as a sweetener sugar substitute by diabetics. Five novel Kluyveromyces marxianus yeast strains, IMB1 - IMB5, have shown the ability to grow on xylose and produce xylitol. In comparison to chemical synthetic xylitol production, the biotechnological production method can be more cost effective, since no expensive metal catalysts and high temperatures are needed. All five yeast strains of K. marxianus 1MB were tested at five different temperatures ranging from 25°C to 45°C with xylose as sole carbon source. IMB4 showed highest growth rate of 0.20 h-1 at 40°C while IMB2 produced the highest xylitol concentration at 40°C with a value of 7.84 g/l (YX/X = 0.42). IMB1 produced the highest ethanol concentration of 1.64 g/l (YE/X = 0.08) at 40°C.
