Provided herein are isolated laccase enzymes and nucleic acids encoding them. Also provided are mediators for laccase reactions. Also provided herein are methods for using laccases to oxidize lignins, other phenolic, and aromatic compounds, such as for bio-bleaching and decolorization of wood pulp under high temperature and pH conditions to facilitate a substantial reduction in use of bleaching chemicals, as well as for treatment of fibers.

Laccases for bio-bleaching

Provided herein are isolated laccase enzymes and nucleic acids encoding them. Also provided are mediators for laccase reactions. Also provided herein are methods for using laccases to oxidize lignins and other phenolic and aromatic compounds, such as for bio-bleaching and decolorization of wood pulp under high temperature and pH conditions to facilitate a substantial reduction in use of bleaching chemicals, as well as for treatment of fibers.

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 astrain. 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

Use of enzymes to reduce aldehydes from aldehyde-containing products

The present invention relates to a novel pulp composition for paper or solid board production comprising an oxidized recovered paper pulp and/or an oxidized mechanical pulp into which from 1 to 500 mmol of carboxyl groups per kg and from 1 to 200 mmol of aldehyde groups per kg have been introduced by oxidation. The invention also relates to paper and solid board based on such a pulp composition and also to a process for producing such paper or solid board. The invention also relates to the use of oxidized recovered paper pulp and/or oxidized mechanical pulp for improving the retention and drainage properties of a pulp suitable for producing paper or solid board. The invention further relates to the use of oxidized recovered paper pulp and/or oxidized mechanical pulp for improving, i.e., increasing, the dry strength of paper and solid board.

Pulp composition for paper and solid board production

A method for preparing substantially enantiopure 3-hydroxy carboxylic acids or esters of the general formula (III) by reacting racemic oxetan-2-ones of the general formula (I) with compounds R3-OH of the general formula (II) in the presence of a lipase fromor, and separating the resulting products of the formula (III) and (IV) from one another where the radicals have the following meaning:R, R, Rindependently of one another H; C-C-substituted or unsubstituted alkyl, substituted or unsubstituted aryl or hetaryl, where Rand Rmay not simultaneously have the same meaning.
