Anaerobes, clostridia included, tend to lack the enzymes catalase or superoxide dismutase, so oxygen is actually toxic to them.
厌氧菌（包括梭菌）一般都缺乏过氧化氢酶或超氧化物歧化酶；因此氧气对他们有毒害。

超氧化物歧化酶
超氧化物歧化酶（英语：superoxide dismutase，缩写SOD）是一种能够催化超氧化物通过歧化反应转化为氧气和过氧化氢的酶。它广泛存在于各类动物、植物、微生物中，是一种重要的抗氧化剂，保护暴露于氧气中的细胞。

Superoxide dismutase (SOD, EC1.15.1.1) is an enzyme that alternately catalyzes the dismutation (or partitioning) of the superoxide (O2) radical into either ordinary molecular oxygen (O2) or hydrogen peroxide (H2O2). Superoxide is produced as a by-product of oxygen metabolism and, if not regulated, causes many types of cell damage. Hydrogen peroxide is also damaging, but less so, and is degraded by other enzymes such as catalase. Thus, SOD is an important antioxidant defense in nearly all living cells exposed to oxygen. One exception is Lactobacillus plantarum and related lactobacilli, which use a different mechanism to prevent damage from reactive (O2).
