2．芽孢杆菌属（Bacillus Cohn ）
伯捷氏细菌分类手册（第七版）中芽孢杆菌属包括25个种，可分为3类：
（1）芽孢不使芽孢囊明显膨大，芽孢壁薄，不易染色，革兰氏阳性。又可以根据菌体粗细分成两类：
菌体粗，直径大于0.9μm ，常见的有巨大芽孢杆菌（Bacillus megaterium ）等；
菌体细，直径小于0.9μm，常见的有枯草芽孢杆菌（B. subtilis）。
（2）芽孢使芽孢囊明显膨大，芽孢椭圆形。可根据发酵糖类产气情况分成两类：发酵糖类产气：常见的有多粘芽孢杆菌（B. polymyxa）；小学生安全教育内容
新年祝福语简短发酵糖类不产气：常见的有嗜热脂肪芽孢杆菌（B. stearothermophilus）。
（3）芽孢使芽孢囊明显膨大，芽孢球形或接近球形。常见的有球孢芽孢杆菌（B. sphaericus）。 聪明的小乌龟
3．假单胞菌属（Pudomonas Migula）
假单胞菌属是一个相当庞大的属，所包括的细菌可氧化多种有机物。伯捷氏细菌分类手册（第七版）列有149个种。
无芽孢的革兰氏阴性细菌，直或微弯的杆菌。以端生鞭毛运动，单毛到丛毛；有少数种不运动。氧化性而非发酵性异氧菌。
