In a biphasic reaction media for the asymmetric biocatalytic reduction of ketones with in situ cofactor regeneration, both enzymes (ADH and FDH) remain stable. Reductions with poorly water-soluble ketones were carried out at substrate concentrations of > 10 mM, and alcohols were formed with good conversions in high enantioselectivity.
