Stored ewe's milk lump cheese is a local product that can be a source of autochthonous beneficial microbiota, especially lactic acid bacteria. The aim of this study was to show the antimicrobial potential of LP17L/1 isolated from stored ewe's milk lump cheese. LP17L/1 is a non-hemolytic, non-biofilm-forming strain, susceptible to antibiotics. It contains genes for 10 bacteriocins-plantaricins and exerted active bacteriocin with in vitro anti-staphylococcal and anti-listerial effect. It does not produce damaging enzymes, but it produces β-galactosidase. It also sufficiently survives in Balb/c mice without side effects which indicate its safety. Moreover, a reduction in coliforms in mice jejunum was noted. LP17L/1 is supposed to be a promising additive for Slovak local dairy products.
储存的母羊奶块状奶酪是一种当地产品，可能是本地有益微生物群的来源，尤其是乳酸菌。本研究的目的是展示从储存的母羊奶块状奶酪中分离出的LP17L/1的抗菌潜力。LP17L/1是一种不溶血、不形成生物膜的菌株，对抗生素敏感。它含有10种细菌素——植物乳杆菌素的基因，并产生具有体外抗葡萄球菌和抗李斯特菌作用的活性细菌素。它不产生破坏性酶，但产生β-半乳糖苷酶。它在Balb/c小鼠中也能充分存活且无副作用，这表明了它的安全性。此外，还注意到小鼠空肠中的大肠菌群有所减少。LP17L/1有望成为斯洛伐克当地乳制品的一种有前景的添加剂。
