厌氧菌可分为有芽胞和无芽胞的两大类。按其对氧的耐受性又可分为厌氧菌、微需氧菌、耐氧菌和兼性厌氧菌四种。早为人们所知的产气荚膜、破伤风和肉毒杆菌就是有芽胞的厌氧菌,而对无芽胞的厌氧菌所知很少。直至近十几年以来,由于厌氧培养技术的进步,培养出许多无芽胞厌氧菌的新种,人们对无芽胞厌氧菌才有了更多的和更新的认识和了解。
Anaerobic bacteria can be divided into two types of spores and non-sprouting. According to its tolerance to oxygen can be divided into anaerobic bacteria, micro-aerobic bacteria, aerobic bacteria and facultative anaerobic bacteria four. As far as is known, the gas capsule, tetanus and botulinum are anaerobic bacteria with spores, and little is known about anaerobic bacteria without spores. Until recent ten years, due to the progress of anaerobic culture technology, many new species of non-spore-forming anaerobic bacteria have been cultivated, and people have more and new understanding and understanding of non-spore-forming anaerobes.
