还原性脱氯是从氯苯中除去一个氯原子，同时获得电子，这大多发生在厌氧条件

Reductive dechlorination removes a chlorine atom from chlorobenzene and obtains electrons at the same time. This occurs mostly under anaerobic conditions, but it may also occur during the aerobic degradation of polychlorinated compounds. Due to the strong attraction of chlorine atoms to the electron cloud, the density of the electron cloud on the benzene ring decreases. The greater the number of chlorine atoms, the lower the electron cloud density on the benzene ring and the more difficult the oxidation. Under anaerobic conditions, the redox potential of the environment is low, and chlorobenzene compounds exhibit good anaerobic biodegradability. Reductive dechlorination requires the participation of various microorganisms. Because multiple microorganisms coexisting easily create an anaerobic environment, and one microorganism relies on other microorganisms as electron acceptors and donors, another microorganism can eliminate inhibited intermediate metabolites with the help of other microorganisms, which can further degrade carry out. The mechanism of chlorobenzene anaerobic biodegradation is mainly hydrogen dechlorination under enzyme catalysis. ㅤ

Because co-existing microbes can easily create anaerobic environments, and one microorganism relies on other microorganisms as electron receptors and donors, another microbe can eliminate inhibited intermediate metabolites with the help of other microorganisms, which can be further degraded.

Reductive dechlorination is the removal of a chlorine atom from chlorobenzene and the acquisition of electrons, which mostly occurs under anaerobic conditions, but may also occur in the aerobic degradation of polychlorinated compounds. Due to the strong attraction of chlorine atom to electron cloud, the density of electron cloud on benzene ring decreases. The more the number of chlorine atoms, the lower the density of electron cloud on benzene ring, and the more difficult the oxidation.

Because the coexistence of a variety of microorganisms is easy to create an anaerobic environment, and one microorganism relies on other microorganisms as electron acceptors and donors, the other microorganism can eliminate the inhibition of intermediate metabolites with the help of other microorganisms, so that further degradation can be completed.
