This invention relates to an inexpensive phytase with a low Km value for phytic acid, DNA coding for the phytase, recombinant DNA having the DNA introduced thereinto, a transformant carrying the recombinant DNA, a process for preparing a phytase by use of the transformant, and an animal feed comprising the phytase.

A novel carbonyl reductase useful for producing alcohol, particularly derivatives of (S)-4-halo-3-hydroxybutyrate ester, is provided. A novel carbonyl reductase derived from Kluyveromyces aestuarii and the nucleic acid encoding the enzyme are provided. The carbonyl reductase has excellent reductase activity and stereoselectivity. The carbonyl reductase reduces ketone to produce alcohol. It can be particularly advantageous when used in industrial production of (S)-4-halo-3-hydroxybutyrate ester.

The invention relates to Tetranectin, a new protein isolated from blood. Its structure comprises four polypeptide chains having the formula shown in the attached drawing. Tetranectin plays a role in the hemostatic system and, therefore, may be used as an agent for regulation of hemostasis. Further, the invention relates to a process for preparing Tetranectin in which Tetranectin is isolated e.g. from blood or blood fractions, cells or genetically engineered organisms. Finally the invention relat...

A nonmetallic cable (20) having utility in an overlay ply (39) of a tire (10) comprises two yarns (21,22). One of the yarns (21,22) has a yarn twist of either zero or is twisted in a first direction. The other yarn (21,22) has a yarn twist that is not zero, but is twisted in a direction opposite to the direction of yarn twist in the first yarn (21,22). The cable (20) has a cable twist that is opposite in direction to the twist of the yarn (21,22) having the larger of the two yarn twists. The cab...

This invention relates to a fiber comprising a major amount of a continous phase comprising one or more melt processible polyesters of fiber forming molecular weight, and a minor amount of one or more polyolefins non-uniformly dispersed in said continuous phase such that the concentration of polyolefins at or near the surface of said fiber is greater than the concentration of polyesters at or near the surface of said fiber, and a process for preparing said fiber.

An improvement in a side bar wafer lock, specifically an improvement in the spring retainer of such a lock, and a method of using the spring retainer in the lock are provided. The improved spring retainer of the invention is provided with barbs on the legs thereof such that when the spring retainer is inserted into the slots of the plug of the wafer lock, the barbs bite into the relatively soft metal of the plug to prevent the dislodging of the spring retainer. The method of the invention compri...

Genes encoding proteins having an activity of desaturating lipid-bound fatty acids at the .DELTA.9 position; vectors which contain the genes or polynucleotides containing part of thereof; plant cells transformed with the genes or polynucleotides containing part of thereof; a method for creating plants by regenerating the plant cells to reproduce mature plants; and plants transformed with the genes or polynucleotides containing part of thereof.

The invention relates to a process for regenerating a cryopump (1) that is equipped with an inlet valve (33), with cold surfaces (6, 8, 11) which have a temperature during operation of the pump that effects the condensation and/or adsorption of gases and which are heated for the purpose of regenerating them, the cryopump further including a backing pump (45) that is connected with the pump interior (9) by way of a valve (44). In this process, heating of the cold surfaces begins if the inlet valv...

The present invention provides a method for production of a spread, comprising the steps of: (a) two aqueous phases with different particle sizes in a fatty phase, of which at least one aqueous phase is dispersed into the fatty phase through a microporous membrane, to prepare a mixed water-in-oil type emulsion; (b) rapidly cooling the emulsion to plasticize; and (c) kneading the plasticized emulsion. According to the present invention, it is possible to produce a low-fat spread having good taste...

Disclosed is a zeolite base catalyst useful particularly for the selective production of para-dialkylsubstituted benzene. The catalyst comprises a porous crystalline zeolite having silica deposited thereon and having incorporated therein phosphorous. Described also in the process for making the catalyst and the parameters for the use of the catalyst in dialkylation processes.
