摘要
从家畜乳汁中分离出乳酸菌菌株，作为潜在的益生菌。对120份牛奶样品(水牛、奶牛和山羊各40份)进行了分析，鉴定出110种乳酸菌，其中43种为益生菌(嗜酸乳杆菌、保加利亚乳杆菌、植物乳杆菌、乳酸乳杆菌和鼠李糖乳杆菌)。其中11株菌株为潜在益生菌，包括L. plantarum (C1、C4、C7、G7、G8和B14)和L. rhamnosus (B13、C5、G4、G10和G18)。他们的细菌素对测试的指示生物显示出广泛的抑制谱。L. plantarum (C4, G7)和L. rhamnosus (G18)产生的细菌素具有显著的抗菌活性，耐121℃高温，耐酸性pH 3，但对pH 9敏感，显示出较强的益生菌潜力。这些独立实验室具有优良的益生菌特性，可用于保护和改善肠道微生物菌群，为消费者的健康带来益处。
Studies on Antimicrobial Activity and Characteristics of Bacteriocins Produced by Lactobacillus strains Isolated from Milk of Domestic Animals
Lactobacilli strains were isolated from the milk of domestic animals for potential probiotic. A total of 120 milk samples (40 each from buffalo, cow and goat) were analyzed and 110 Lactic Acid Bacteria (LAB) were identified, out of these 43 were identified as probiotics, (L. acidophilus, L. bulgaricus, L. plantarum, L. lactis and L. rhamnosus). Out of these, 11 isolates were potential probiotics, which includes L. plantarum (C1, C4, C7, G7, G8 and B14) and L. rhamnosus (B13, C5, G4, G10 and G18). Their bacteriocins showed a broad inhibitory spectrum against the indicator organisms tested. The bacteriocins produced by L. plantarum (C4, G7) and L. rhamnosus (G18) showed prominent antimicrobial activity, resistance to heat at 121 C and tolerate acidic pH 3 but sensitive to pH 9 indication strong probiotic potential. These isolated LABS, exhibiting excellent probiotic characteristics, can be use in the protection and improvement of intestinal microbial flora and contribute health benefits to consumers.
