The present invention relates to a process for the production of one or more fermentation product from a sugar composition, comprising the following steps: a) fermentation of the sugar composition in the presence of a yeast belonging to the genera Saccharomyces, Kluyveromyces, Candida, Pichia, Schizosaccharomyces, Hansenula, Kloeckera, Schwanniomyces or Yarrowia: and b) recovery of the fermentation product,
wherein the yeast comprises the genes araA, araB and araD and the sugar composition comprises glucose, galactose and arabinose.

The present invention relates to bacterial cells genetically modified to improve their tolerance to certain commodity chemicals, such as diacids, and to methods of preparing and using such bacterial cells for production of diacids and other compounds.
