Use of oxidoreductases in bleaching and/or detergent compositions and their preparation by microorganisms engineered by recombinant DNA technology

摘要

The structural genes and their regulatory DNA sequences of an alcohol oxidase (MOX) and a dihydroxyacetone synthase (DHAS) of Hansenula polymorpha have been isolated and the nucleotide sequences determined. The invention relates to the use of the MOX gene, as well as the use of the regulatory DNA sequences of MOX and/or DAS in combination with the MOX gene, optionally after modifica­tion thereof, or other oxidase genes, or other genes, to produce engineered microorganisms, in particular yeasts.;Said engineered microorganisms can produce oxidases or other enzymes in yields that allow industrial application on a large scale.;Moreover, said engineered microorganisms can produce oxidases having improved properties with respect to their application in oxidation reactions and/or in bleaching and detergent products.
