摘要:
Certain specified variants of a parent lipase belonging to the Pseudomonas sp. lipase family have improved properties, in particular improved washing properties. The lipase variants of the invention have an amino acid sequence comprising substitution, deletion or insertion of an amino acid at one or more specified positions of the parent lipase. The invention also provides methods of preparing such lipase variants.
摘要:
Novel lipases from strains of the genera Pseudomonas and Acinetobacter are well suited for use in detergents to improve the removal of fatty soiling. They have activity throughout a temperature range of 1 to 65 °C, a pH range of 8-12, at high concentrations of anionic surfactant and in the presence of bleach.
摘要:
The present invention relates to enzyme-containing granules comprising (a) an enzyme and (b) a core which intrinsically is capable of absorbing at least 5% w/w (based on the weight of the core) of water and to processes for the production of such granules comprises (a) contacting absorbent cores, capable of absorbing at least 5% w/w (based on the weight of the core) of water, with a liquid medium, such as an aqueous medium, containing an enzyme in dissolved and/or dispersed form, the amount of the liquid medium employed being such that substantially no attendant agglomeration of the resulting product occurs; and (b) at least partially removing volatile components of the liquid medium from the resulting product.
摘要:
Novel lipolytic enzymes are disclosed which are capable of removing substantial amounts of lard from a lard stained swatch in a one cycle wash. Preferred lipolytic enzymes are variants of the Humicola lanuginosa lipase which may be prepared by recombinant DNA techniques. The enzymes are advantageously used in detergent compositions.
摘要:
Protein is removed from rubber latex articles (such as rubber gloves) by washing the articles with a solution containing a soluble silicate. Optionally, the solution may also contain a protease.
摘要:
A lipolytic enzyme with high activity at alkaline pH in the absence of Ca++ can be obtained from strains of filamentous fungi belonging to the genus Absidia. The lipolytic enzymes are effective for improving the effect of detergents towards fatty soiling.
摘要:
The method for processing of potatoes is characterized by the fact that the method is carried out in a potato processing plant, which comprises an oil separator, heating equipment and at least one enzyme reactor and which is modified in such a manner that it can also be used for processing of rape. It is not obvious that such modification is sufficiently small for achieving an economically sound method for processing of rape outside the potato season.
摘要:
On décrit un procédé permettant de prévenir plus efficacement les problèmes de brai dans un procédé de production de pâte mécanique ou dans un procédé de fabrication de papier utilisant de la pâte mécanique. Procédé de fabrication de papier utilisant l'addition d'une enzyme d'hydrolyse de glycéride d'acides gras pouvant résister à des températures supérieures à 70 °C, à la matière brute ou à l'eau blanche de fabrication de papier que l'on soumet à des températures supérieures à 70 °C.
摘要:
La résine peut être hydrolysée de manière enzymatique au cours du blanchiment réducteur (par exemple à l'aide de dithionite de sodium) utilisé communément lors de la fabrication de pâte à papier. Le traitement enzymatique requiert peu ou pas de changements dans les conditions de blanchiment communément pratiquées.
摘要:
Lors de la préparation de la pâte à papier pour la fabrication du papier, on peut améliorer les propriétés d'égouttage en traitant la pâte à papier avec de la cellulase à haute consistance (plus de 8 %)
