摘要:
Alkaline cellulases having an optimum pH in an alkaline range and being stable over a broad pH range are produced by microorganisms which belong to the genus Bacillus and grow in a neutral medium.These alkaline cellulases are rarely inhibited by ingredients ordinarily incorporated in detergents such as surface active agents, proteinases and chelating agents, so that they can be conveniently used in detergent compositions.
摘要:
Novel alkali-resistant cellulases which have an optimum pH at a neutral region and have a high relative activity in an alkaline region are produced by microorganisms belonging to the genus Bacillus and growing in neutral medium.The cellulases suffer little inhibition by means of detergent ingredients such as surface active agents, proteinases and chelating agents. Therefore, they can be conveniently used as one of ingredients for detergent compositions.
摘要:
DNA frangments containing an alkaline cellulase K gene, which comprise about 4.0, about 2.4 and about 1.9 kilo base pairs, respectively, each having a specific restruction map, recombinant plasmids containing any of these DNA fragments, and recombinant microorganisms harboring any of said plasmids.The alkaline cellulase K gene is derived from a bacterial strain which belongs to the genus Bacillus and is alkalophilic, that is, capable of revealing an optimum growth in an alkaline pH region.
摘要:
A toothpaste filled in a container which has two chambers and is capable of simultaneously discharging two different compositions filled respectively in the two chambers when the main body of the container is pressed, wherein a ratio of a storage modulus GA′ of Composition (A) filled in one chamber to a storage modulus GB′ of Composition (B) filled in the other chamber falls within a range of from 0.6 to 1.4. By controlling the ratio, it is possible to stably discharge from the container storing these two compositions separately predetermined amounts of these two compositions which will otherwise cause a time-dependent change if they are pre-mixed thereby failing to attain the purpose of their addition.

摘要:
A composition for use in the oral cavity is disclosed. The composition comprises (A) an antibacterial compound represented by the following general formula (1),A.sup.m+ .multidot.X.sub.m.sup.- (1)wherein A.sup.m+ is a nitrogen-containing antibacterial cation and the counter anion X.sup.- represents a monoalkyl phosphate ion, a monoalkenyl phosphate ion, a monoalkyl phosphonate ion, or a monoalkenyl phosphonate ion having a linear or branched alkyl or alkenyl group with 8 to 20 carbon atoms, and m is a valence of the cation A, and (B) a vehicle for use in the oral cavity. It exhibits a remarkablely rapid and continued disinfection effect action against oral cavity bacteria, while providing a good taste. Its disinfection effect is not reduced in the presence of surfactants. In addition, it does not color the tooth.
