摘要:
An immobilized enzyme is prepared for use in organic mediums essentially devoid of free water. An enzyme-containing liquid medium is contacted with a particulate porous carrier which preferably has a particle size of 200-1000 &mgr;m and a surface area of 20-1000 m2/g to adsorb the enzyme on the carrier, and volatile components of the liquid medium contained by the carrier are removed. The carrier may have a hydrophilic surface, and an amount of liquid medium is used to prevent agglomeration of the carrier. Alternatively, the carrier has a hydrophobic surface, and the addition of a hygroscopic substance suppresses agglomeration of the carrier by absorbing excess liquid. The hygroscopic substance may be removed during the removal of volatile components. Contacting of the enzyme-containing liquid and carrier can be in a fluidized bed where immobilization and removing volatile components are conducted simultaneously, or contacting can be in mixer followed by removing volatile components in a fluidized bed. The enzyme-containing liquid may be atomized onto the carrier in the fluidized bed or in the mixer. Enzymes immobilized include lipase, and the immobilized lipase can be used in trans-esterification reactions.
摘要:
The present invention relates to methods of dyeing a material, comprising (a) soaking the material in an aqueous solution which comprises one or more mono-, di- or polycyclic aromatic or heteroaromatic compounds; and (b) treating the soaked material in an aqueous solution with (i) a hydrogen peroxide source and an enzyme exhibiting peroxidase activity or (ii) an enzyme exibiting oxidase activity on the one or more aromatic or heteroaromatic compounds; wherein the material is a fabric, yarn, fiber, garment or film made of fur, hide, leather, silk or wool.
摘要:
The present invention relates to the use of a haloperoxidase in combination with a hydrogen peroxide source for reducing the malodor emanating from soiled hygiene products. The invention also relates to hygiene products with reduced malodor in soiled state.
摘要:
The transfer of a textile dye from a dyed fabric to another fabric during washing or rinsing is inhibited by adding an enzyme exhibiting peroxidase activity or an enzyme exhibiting a suitable oxidase activity to the wash liquor in which said fabrics are washed and/or rinsed. Peroxidase is produced extracellularly by some strains of Bacillus pumilus. The novel peroxidase preparation from B. pumilus is a microperoxidase, i.e. it contains hemopeptide as an active component. The preparation has improved stability at high temperature, at high pH and at high concentrations of hydrogen peroxide. It can be produced without undesired catalase activity.

摘要:
Esters of monosaccharides and their lower alkyl glycosides are effective both as suffactants and as bleach activators (peracid precursors). The compounds are non-toxic and biodegradable. They act as nonionic suffactants and are effective in soil removal from textiles, e.g. of fatty soiling. In the presence of a hydrogen peroxide source, the sugar derivatives are perhydrolyzed during the washing process to form long-chain peracid. This enhances the bleaching effect, especially on hydrophobic stains.
摘要:
Fatty acid esters of methyl glycosides are prepared by reacting a fatty acid or ester with a methyl glycoside in the presence of an enzyme catalyst, in particular a lipase. The resulting fatty acid esters are preferably monoesters.The methyl glycoside fatty acid esters may be used as surface-active agents in cleaning compositions or personal care products.
