    摘要: The present invention is intended to provide novel genes participating in acetic acid tolerance of acetic acid bacteria, and a method of improving acetic acid tolerance of microorganisms, particularly that of acetic acid bacteria by using the genes, further a method of efficiently producing vinegar with acetic acid at higher concentration by using acetic acid bacteria whose acetic acid tolerance is improved. In the present invention, novel genes having a function for improving acetic acid tolerance on practical level were cloned from practical acetic acid bacteria belonging to the genus Gluconacetobacter by a method of obtaining genes from chromosomal DNA library that enable to grow on the medium at a high concentration of acetic acid. Further, in transformants in which the genes were introduced into acetic acid bacteria, acetic acid tolerance was remarkably increased, and when the transformants are subjected to aeration culture in the presence of ethanol, the growth lag-time can be shortened, and the growth rate can also be improved, moreover the final acetic acid concentration can be remarkably improved.

    摘要: Provided is a method of efficiently and economically producing a sialic acid compound-containing composition, in which a content rate of a sialic acid compound is remarkably high, from natural raw materials containing a sialic acid compound such as milk, whey, or a processed product thereof. The present invention provides a method of producing a sialic acid compound-containing composition, comprising: using, as a raw material, a liquid raw material containing a sialic acid compound or a liquid in which a solid raw material containing the sialic acid compound is dissolved or suspended in water; culturing, in the raw material, a microorganism which cannot assimilate the sialic acid compound and can assimilate carbohydrates other than the sialic acid compound contained in the raw material; allowing the microorganism to assimilate the carbohydrates other than the sialic acid compound contained in the raw material; and removing the microorganism.
