Abstract

See full text

The invention relates to the use of an enzyme preparation which catalyzes the degradation of formaldehyde for reducing the formaldehyde content in a formaldehyde-containing formulation. In a preferred embodiment, the enzyme preparation contains a formaldehyde dismutase from a Pseudomonas putida strain. Further, the invention refers to a process for reducing the formaldehyde content in cross-linking agents for textile finishing or in polymer dispersions used, e.g. in construction chemistry. Further the invention relates to the use of an enzyme preparation which catalyzes the degradation of aldehydes for reducing the formaldehyde content in an aldehyde-containing formulation. Furthermore, the invention relates to a novel variant of the formaldehyde dismutase from Pseudomonas putida.
