中国微生物菌种查询网 / 2018-11-09 10:28:05

        脆弱拟杆菌能分解糖,对胆汁耐受。为类杆菌属的代表株。革兰氏阴性杆菌,两端钝圆而浓染,中间有不着色部份。在正常情况下,它能维持消化系统平衡和机体抵抗力,是免疫系统的驱动力,已被应用于健康领域。脆弱类杆菌专性厌氧、无芽胞、无动力、直径为0.5×1.3~1.6μm 。专性厌氧菌,氯化血红素和20%胆汁可促进其生长。牛心、牛脑液血平皿培养48小时,菌落1~3mm ,圆,微凸,灰白,表面光滑,边缘整齐,大多不溶血。生化反应弱,解糖。解酶反应阳性,葡萄糖的终末代谢产物有乙酸和琥珀酸;吲哚不定,耐胆盐,水解七叶灵。不还原硝酸盐。产生苹果酸盐脱氢酶、谷氨酸脱氢酶、葡萄糖6磷酸脱氢酶(g6pdh)、6磷酸葡萄糖脱氢酶(6pgdh)、细胞壁粘肽层含有二氨基庚二酸。依据对鼠李糖、海藻糖,甘露醇发酵及吲哚试验可区别本组菌落。DNA的G C含量为39~48%。本菌主要分布于结肠和口腔中。
