- W957194798 abstract "采用体外拮抗试验方法,研究了2株分离自斜带石斑鱼幼鱼肠道的乳酸菌（MM1和MM4）的产酸能力及抑菌特性。结果表明,MM1产乳酸速度较快,且整个培养期间乳酸产量均显著高于MM4（P〈0.05）。MM1和MM4对革兰氏阴性细菌梅氏弧菌、哈维氏弧菌和革兰氏阳性细菌金黄色葡萄球菌均有强烈的抑制作用,但乳酸对2株乳酸菌的抑菌活性没有影响。过氧化氢酶显著降低了2株乳酸菌对梅氏弧菌和哈维氏弧菌的抑菌活性（P〈0.05）,但对金黄色葡萄球菌的抑菌活性影响较小,提示2株菌除能产生过氧化氢外,还能产生其它抑菌物质。2株乳酸菌产生的抑菌物质具有一定的热稳定性,对蛋白酶部分敏感,经3种蛋白酶（胃蛋白酶、胰蛋白酶和蛋白酶K）处理后,均保留70.0%以上的抑菌活性。因此,2株乳酸菌产生的抑菌物质具有热稳定性和蛋白酶部分敏感特性,且对革兰氏阴性菌和阳性菌均具有抑制效果,可推测为类细菌素物质。" @default.
