A broad range of arylaliphatic ketones is efficiently reduced to the corresponding optically active (R)-alcohols by a recombinant alcohol dehydrogenase (PF-ADH) produced by overexpression in 'Escherichia coli'. PF-ADH shows high activity and stereoselectivity in the reduction of acetophenone and various derivatives (45-99\%), as well as in the reduction of 3-oxy-butyric acid methyl ester and 3-oxy-butyric acid methyl ester and 3-oxy-hexanoic acid ethyl ester (>99\%). The highest activity was observed between 10 and 20°C. The copfactor NADH can be efficiently recycled by the addition of 10-20\% of iso-propanol. A flow-through-polarimetry-based assay to determine oxidoreductase activity and stereoselectivity is described.}, language = {en} }
