中国人. 以Oenococcus oeni苹果酸通透酶基因为目标基因，设计了1对特异性引物PmlepL/PmlepR进行酒酒球菌的快速鉴定研究。结果表明，直接以O.oeni的菌落为模板，通过PmlepL/PmlepR引物的PCR扩增，可得到苹果酸通透酶基因的特异性条带；用此特异性引物进行供试乳酸菌的PCR鉴定，所有O.oeni菌系均得到特异性条带，而供试的其他种类乳酸菌未扩增出目标带。引物PmlepL/PmlepR可用于O.oeni的快速PCR鉴定。

The result indicated that specific stripes of mleP gene could be cloned by PCR from colonies of O. oeni directly. Meanwhile, the specific stripes of mleP gene could be cloned by PCR from all the strains of O. oeni but failed from several other species of lactic acid bacteria. The PCR assay confirmed to be specific for O. oeni species and can be used for rapid identification of O. oeni.
