植物乳杆菌（LactobacillusplantarumJ51）是从一种葡萄酒中分离得到的一株具有抗菌活性的菌株。这些特性赋予了L. plantarum J51在葡萄酒微生物学和细菌素生产的研究中具有很高的兴趣。本工作观察到细菌素的产生受“群体感应”机制的调控，并对细菌素产生菌L. plantarum J51是完全特征化的。对20，667bp的片段进行了完全测序（GenBank登录号DQ 340868），并显示了五个操纵子（plNC 8 β α c、plnLR样、plnABCD. plnanosis，plnGHSTUVW）和一个含有一个假定操纵子的新区域，该操纵子具有三个新的orfs，可以编码一个假定的两肽细菌素。(c)2008 Elsevier B.V.保留所有权利。
Lactobacillus plantarum J51 strain was isolated from a Rioja red wine and it showed bacteriocin activity against a wide range of lactic acid bacteria of oenological importance. These characteristics conferred L. plantarum J51 a high interest both in wine microbiology and in the study of bacteriocin production. In this work the bacteriocin production regulated under the "quorum-sensing" mechanism is observed and the pin locus of the bacteriocin-producing L. plantarum J51 is fully characterized. A 20,667 bp fragment was completely sequenced (GenBank accession number DQ340868), and showed five operons (plNC8 beta alpha c, plnLR-like, plnABCD. plnEFI, plnGHSTUVW) and a new region containing a putative operon with three new orfs that could encode a putative two-peptide bacteriocin.
