Lactobacillus rhamnosus R-2002 strain isolated from Armenian pickled cheese sample has a fungicide effect, which was carried out by the first-time designed method. The fungicide effect of LAB strain was expressed after 5 days of co-cultivation with Mucor plumbeus and 6 days of co-cultivation with Penicillium aurantioviolaceum. The growth as well as the antifungal activity of L. rhamnosus R-2002 was shown to directly depend on the nature of the medium's carbon source. The antifungal activity of this strain against both moulds was inhibited when the combination of 10 g l glucose and 10 ml l ethanol in the medium was used as a carbon source. The results could be applied in food industry, medicine, and veterinary.
从亚美尼亚腌制奶酪样品中分离出的鼠李糖乳杆菌R-2002菌株具有杀真菌作用，这是通过首次设计的方法实现的。乳酸菌菌株的杀真菌作用在与铅绿毛霉共培养5天以及与橘黄青霉共培养6天后表现出来。结果表明，鼠李糖乳杆菌R-2002的生长及其抗真菌活性直接取决于培养基碳源的性质。当培养基中10 g/l葡萄糖和10 ml/l乙醇的组合用作碳源时，该菌株对两种霉菌的抗真菌活性均受到抑制。这些结果可应用于食品工业、医学和兽医学领域。
