Beschreibung
Zusammenfassung:	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 formal dehyde 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. Cette invention concerne l'utilisation d'une préparation enzymatique qui catalyse la dégradation du formaldéhyde pour réduire la teneur en formaldéhydes d'une formulation contenant des formaldéhydes. Dans un mode de réalisation préféré, la préparation enzymatique contient un formaldéhyde dismutase provenant d'une souche de Pseudomonas putida. L'invention concerne, en outre, un procédé pour réduire la teneur en formaldéhydes dans des agents de réticulation pour finition textile ou dans des dispersions polymères utilisées, par exemple, dans la chimie de la construction. Cette invention concerne, en outre, l'utilisation d'une préparation enzymatique qui catalyse la dégradation des aldéhydes pour réduire la teneur en formaldéhydes d'une formulation contenant des aldéhydes ainsi qu'un nouveau variant du formaldéhyde dismutase provenant de Pseudomonas putida.
