    摘要: The invention provides a glucose dehydrogenase that is an extremely stable enzyme having a thermostability of 80° C. or more, and that does not substantially act upon saccharides other than glucose (e.g., having a reactivity of less than 3% with respect to maltose, galactose, and xylose). The invention also provides a method for producing such an enzyme, and a composition for quantifying glucose using such an enzyme.

    摘要: A method for high-density culture of a microorganism is proposed. This method is characterized by adjusting the cultivation temperature to a level lower than the optimum temperature for growth thereby causing the specific growth rate of the microorganism to reach a level of not more than 20% of the specific growth rate at the optimum temperature for growth. By this method of culture, it is made possible to culture the microorganism at a very high density. Further, this method of culture enables a useful substance, particularly an active type recombinant protein, to be produced in a large amount at a very low cost with high efficiency.

    摘要: It is intended to provide an efficient and sure gene targeting method embodied at an arbitrary position in the genome of an organism and a kit therefor. It is also intended to provide a method for targeted-disruption of an arbitrary gene in the genome of an organism which comprises: 1) the step of providing the whole sequencial data of the genome of the organism; 2) the step of selecting at least one arbitrary region in the sequence; 3) the step of providing a vector containing a sequence homologous with the region selected above and a marker gene; 4) the step of transforming the organism by the vector; and 5) the step of providing the organism under such conditions as allowing homologous recombination. Moreover, the genome of a hyperthermostable bacterium and its array are provided.
