Abstract
Biotransformation of 2-chlorophenol by a methanogenic sediment community resulted in the transient accumulation of phenol and benzoate. 3-Chlorobenzoate was a more persistent product of 2-chlorophenol metabolism. The anaerobic biotransformation of phenol to benzoate presumably occurred via para-carboxylation and dehydroxylation reactions, which may also explain the observed conversion of 2-chlorophenol to 3-chlorobenzoate.
摘要
产甲烷沉积物群落对2-氯苯酚的生物转化导致了苯酚和苯甲酸盐的短暂积累。3-氯苯甲酸盐是2-氯苯酚代谢中更持久的产物。苯酚厌氧生物转化为苯甲酸盐可能是通过对羧化和脱羟基反应发生的，这也可能解释了观察到的2-氯苯酚向3-氯苯甲酸盐的转化。
