1.1.5.7	additional information	the localization of the enzyme on the outer surface of the organism is advantageous to facilitate the oxidative fermentation of the cyclic alcohols. Since cyclic alcohols have some biological toxicity to living cells, according to the mechanism of the oxidative fermentation, there is no need to incorporate such toxic compounds into the cytoplasm to oxidize and pump out the oxidation products across the cytoplasmic membrane by the expense of bioenergy. The enzyme not inducible
