  • Patent number: 9428775
    Abstract: Disclosed is the biological production of lactic acid using a microorganism. A transformant capable of producing lactic acid of high optical purity at high yield, a method for the preparation thereof, and a method for producing lactic acid in a convenient and economically beneficial manner using the same are provided. The Zymomonas mobilis transformant can produce lactic acid of high optical purity at high yield without a stringent limitation to production conditions and a regulation of the intracellular metabolism pathway. Because it requires no additional separation and purification steps, the use of the transformant allows the production of lactic acid in a short process, resulting in a significant reduction in production cost, and avoiding the environment problems caused by precipitate wastes, which brings about environmental issues.
    Type: Grant

  • Publication number: 20100210469
    Abstract: The present invention relates to techniques to detect chromosomal columns abnormalities. More specifically, the present invention is directed to a microarray chip for detecting chromosomal abnormalities comprising one or more pooled probe sets, wherein the pooled probe set is specific to a chromosomal abnormality and all probes of each pooled probe set are immobilized together in at least one spot; a method of detecting chromosomal abnormalities using the microarray chip; a kit for diagnosing diseases associated with chromosomal abnormalities comprising the microarray chip; and a method of diagnosing a disease associated with a chromosomal abnormality by identifying the chromosomal abnormality specific to the disease using the microarray chip. The present invention relates to techniques to detect chromosomal abnormalities.
