Title: Process for preparing a catalase-free oxidase
Inventor: GIUSEPPIN MARCO LUIGI FEDERICO
IPC: C11D3/386
Filed: 1988-05-05
Abstract: The oxidase, eg methanol oxidase, is produced by aerobic fermentation of a catalase-negative yeast in the presence of:   (a) a compound which induces the expression of the oxidase gene but is not a substrate for the oxidase, such as formiate or formaldehyde;   (b) a so-called inducing substrate that induces expression of the oxidase gene and may also be substrate for the oxidase such as methanol; and (c) another source of carbon that is suitable for the yeast species chosen, the molar ratio of inducing compound not being a substrate : inducing substrate : other source of carbon being such that the yeast formed and the oxidase formed do not suffer any harmful effects from the oxidation of the inducing substrate.   The ratios of (a), (b) and (c) are within the ranges given in EP-A-O 242 007 and EP-A-O 244 920, but the dilution rate has to be adapted to a relatively low value for optimal production of the oxidase, when the amount of (c) is relatively low compared with that of (a) and (b). For example, methanol oxidase is formed by induction with technical formaldehyde (a), containing some methanol (b), in the presence of glucose (c). Exemplified is the yeast Hansenula polymorpha, mutant 55/11, ATCC 46059. The catalase-free oxidase can be used for producing hydrogen peroxide, e.g. in a washing or bleaching process or for determination of ethanol or amines, or as a catalyst for oxidation reactions.
