    摘要: A method of producing 3-oxoadipic acid from an aliphatic compound easily utilizable by a microorganism, such as a saccharide, by utilization of a metabolic pathway of the microorganism is disclosed. The method of producing 3-oxoadipic acid includes the step of culturing at least one type of microorganism having a capacity to produce 3-oxoadipic acid, selected from the group consisting of, for example, microorganisms belonging to the genus Serratia, microorganisms belonging to the genus Corynebacterium, microorganisms belonging to the genus Hafnia, microorganisms belonging to the genus Bacillus, microorganisms belonging to the genus Escherichia, microorganisms belonging to the genus Pseudomonas, microorganisms belonging to the genus Acinetobacter, microorganisms belonging to the genus Alcaligenes, microorganisms belonging to the genus Shimwellia, microorganisms belonging to the genus Planomicrobium, microorganisms belonging to the genus Nocardioides, microorganisms belonging to the genus Yarrowia, microorganisms belonging to the genus Cupriavidus, microorganisms belonging to the genus Rhodosporidium, microorganisms belonging to the genus Streptomyces, and microorganisms belonging to the genus Microbacterium.

    摘要: Provided is a transformant which can produce lactic acid with a high productivity without requiring neutralization with an alkali and is excellent in both of lactic acid production capability and growth ability and its production process, and a method for producing lactic acid by using the transformant.A transformant containing from 3 to 5 copies of a lactate dehydrogenase gene derived from human and introduced into a Schizosaccharomyces pombe host, wherein a gene that is a part of a group of genes encoding pyruvate decarboxylase of the Schizosaccharomyces pombe host is deleted or inactivated. A transformant characterized by providing a cell concentration of at least 4.0 g (on a dry cell weight basis)/L of a culture broth prepared by inoculating cells, at an initial cell concentration of 0.04 g (on a dry cell weight basis)/L, into a 500 mL Sakaguchi flask containing 100 mL of a liquid culture broth which includes 1% of yeast extract, 2% of peptone and 6% of glucose, and then cultivating 20 hours at a temperature of 32° C. under shaking conditions of 110 rpm and 7 cm stroke, and providing a lactic acid concentration of at least 80 g/L of a fermentation liquor prepared by inoculating cells obtained by cultivating 20 hours under the above-described conditions, at an initial cell concentration of 36 g (on a dry cell weight basis)/L, into a 11.1% glucose aqueous solution, and then fermenting 3 hours at a temperature of 32° C. under shaking conditions of 110 rpm and 7 cm stroke. A method for producing lactic acid by using these transformants.
