Abstract
Recombinant microorganisms are useful for producing xylitol by fermentation of arabinose. The recombinant microorganisms are produced by transformation of host microorganisms with heterologous polynucleotide sequences coding for each of L-xylulose reductase, D-tagatose 3-epimerase, and L-arabinose isomerase, which transformants express the heterologous polynucleotides at a sufficient functional level to be effective to produce xylitol from arabinose. Production of xylitol is effected by contacting these recombinant microorganisms with a substrate comprising arabinose under conditions effective to produce xylitol from arabinose.
