⑤选择性培养分离法 为了从混杂的微生物群体中分离出某种微生物,可 以根据该微生物的特点,包括营养、生理、生长条 件等,采用选择培养的方法进行分离。 *利用选择培养基进行直接分离 *富集培养

⑥单细胞(单孢子)分离法 采用显微分离法从混杂群体中直接分离单个细胞或单个个体 进行培养以获得纯培养的方法。该方法要在显微镜下进行。 毛细管法:用毛细管提取微生物个体,适合于较大微生物。 显微操作仪:用显微针、钩、环等挑取单个细胞或孢子以获 得纯培养。 小液滴法:将经过适当稀释后的样品制成小液滴,在显微镜 下选取只含一个细胞的液滴来进行纯培养物的分离

⑦膜过滤法 When there is a small number of organisms in a large amount of liquid, the liquid is filtered through a membrane and then the membrane is placed on agar in a petri dish
