摘要:
A microorganism belonging to the genus Bacillus is cultured and thiopeptide compounds QN3323 and thiocillin I/II compounds are collected from the culture medium. The compounds are useful as drugs to treat infections caused by multidrug-resistant bacteria.

Present invention provides a method to efficiently manufacture an oil-containing product including long chain polyunsaturated fatty acid, or a high added value oil containing long chain polyunsaturated fatty acids. The method comprises culturing a microorganism belonging to the Genus Labyrinthula. The Labyrinthula microorganism is cultured in a medium containing oil or fatty acid as a carbon source, and the produced long chain polyunsaturated fatty acid is recovered from the culture. With the present invention, it is possible to efficiently produce from the vegetable oil and the like, an oil containing product comprising long chain polyunsaturated fatty acids such as docosahexanoic acid having a carbon number of 20 or more, and two or more unsaturated bonds, or an oil containing the long chain polyunsaturated fatty acid. Further, the method of the present invention may be used to reform oil by converting the plant oil and like to high added value oil containing the long chain polyunsaturated fatty acid.

A novel nucleic acid probe for nucleic acid determination includes a single-stranded nucleic acid labeled with plural fluorescent dyes containing at least one pair of fluorescent dyes to induce FRET, the pair of fluorescent dyes including a fluorescent dye (a donor dye) capable of serving as a donor dye and a fluorescent dye (an acceptor dye) capable of serving as an acceptor dye, in which the nucleic acid probe has such a base sequence and is labeled with the fluorescent dyes so that the fluorescence intensity of the acceptor dye decreases upon hybridization with a target nucleic acid. A novel nucleic acid determination method uses the probe. The probe and method can determine one or more types of target nucleic acids in an assay system in parallel using a simple apparatus.

摘要:
A method is provided for determining a concentration of a target nucleic acid by using a nucleic acid probe labeled with a fluorescent dye. The method comprises: providing, as the probe, a nucleic acid probe capable of reducing fluorescence emission from the fluorescent dye when hybridized with the target nucleic acid; hybridizing the probe to the target nucleic acid; and measuring a decrease in fluorescence emission from the fluorescent dye after the hybridization relative to fluorescence emission from the fluorescent dye before the hybridization.
