CONVERSION OF KETONES AND ALCOHOLS BY A MICROBIAL NADP-DEPENDENT ALCOHOL DEHYDROGENASE
Michele Vitolo*
ABSTRACT
Alcohol dehydrogenase from Thermoanaerobium brockii (ADH), depending on the pH of reaction medium, catalyzes the reduction of ketones to alcohols with the simultaneous consumption of NADPH and vice-versa. Ketone reduction and alcohol oxidation occur at acid and alkaline pH, respectively. The capability of ADH to catalyze both ketone reduction and alcohol oxidation under different reaction conditions opens the possibility to develop processes in a membrane bioreactor operated in continuous mode to produce chiral alcohols from prochiral ketones. Preliminary data has shown that 1- Keywords: Alcohol dehydrogenase, NADP, NADPH, Ketones, Alcohols. [Download Article] [Download Certifiate] |
