[Induced methanol dehydrogenase in the yeast Hansenula polymorphia DL-1].

The yeast Hansenula polymorpha DL-I showed NAD-specific dehydrogenase activity involved in the methanol primary oxidation. This enzyme was found to be induced during periodic and continuous H. polymorpha cultivation, using methanol as the sole source of carbon and energy. The enzyme was absent during yeast cultivation on the glucose and ethanol containing medium.
