Summary
With propene-grown cells of Xanthobacter Py2 it was possible to resolve racemic mixtures of 2,3-epoxyalkanes. Only 2S-forms were metabolized by this organism, resulting in pure 2R-2,3-epoxyalkanes. Chiral resolution was obtained with trans-2,3-epoxybutane, trans-2,3-epoxypentane and cis-2,3-epoxypentane. Xanthobacter Py2 was however not able to discriminate between the enantiomeric forms of 1,2-epoxyalkanes, resulting in the complete degradation of both chiral forms of 1,2-epoxyalkanes.
