Probiotic properties including antioxidant and immune-enhancing effects of 200655 isolated from kimchi were evaluated. The tolerance of three strains ( 200655, KCTC 3108, and GG to bile salts (0.3% oxgall, 24 h) was similar, and 200655 showed the highest tolerance to gastric juice (0.3% pepsin, 3 h). All strains presented similar autoaggregation ability. 200655 showed higher cell surface hydrophobicity and adhesion ability on HT-29 cells. 200655 did not produce β-glucuronidase and was sensitive to ampicillin, tetracycline, chloramphenicol, and doxycycline. Additionally, 200655 showed the highest antioxidant effects in DPPH and ABTS radical scavenging, and β-carotene bleaching assays. RAW 264.7 cells treated with 200655 produced more nitric oxide, induced nitric oxide synthase, and cytokine related to immune-enhancing effects such as interleukin-1β and interleukin-6. Therefore, 200655 could be useful as a probiotic strain for older people.
对从泡菜中分离出的200655的益生菌特性(包括抗氧化和免疫增强作用)进行了评估。三株菌株(200655、KCTC 3108和GG)对胆盐(0.3%牛胆盐,24小时)的耐受性相似,且200655对胃液(0.3%胃蛋白酶,3小时)的耐受性最高。所有菌株均表现出相似的自聚集能力。200655在HT-29细胞上表现出更高的细胞表面疏水性和黏附能力。200655不产生β-葡萄糖醛酸酶,且对氨苄青霉素、四环素、氯霉素和强力霉素敏感。此外,200655在DPPH和ABTS自由基清除以及β-胡萝卜素漂白试验中表现出最高的抗氧化作用。用200655处理的RAW 264.7细胞产生了更多的一氧化氮、诱导型一氧化氮合酶以及与免疫增强作用相关的细胞因子,如白细胞介素-1β和白细胞介素-6。因此,200655可作为老年人的益生菌菌株。
