Abstract: 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.

Abstract: The present invention relates to methods for preparing an aqueous acrylamide solution having a low acrylic acid concentration. In addition, the present invention relates to methods for reducing the acrylic acid concentration of an aqueous acrylamide solution. The methods involve a bioconversion of acrylonitrile to acrylamide in the presence of a biocatalyst, wherein during the bioconversion the content of acrylonitrile is maintained at 0.3 w/w % or more referred to the total weight of the composition in the reactor. Also provided is an aqueous acrylamide solution which is obtained by the methods of the present invention. Furthermore, the present invention is related to an acrylamide homopolymer or copolymer obtained by polymerizing the acrylamide of the aqueous solution.
