Abstract
The biodegradability of dicamba was investigated under anaerobic conditions with a consortium enriched from wetland soil. Degradation proceeded through an initial demethylation reaction, forming 3,6-dichlorosalicylic acid, followed by reductive dechlorination, forming 6-chlorosalicylic acid. The consortium, consisting of a sulfate reducer, three methanogens, and a fermenter, was unable to mineralize the aromatic ring.
摘要
在厌氧条件下，利用从湿地土壤中富集的微生物群落研究了麦草畏的生物降解性。降解过程首先是脱甲基反应，生成3,6-二氯水杨酸，随后是还原脱氯反应，生成6-氯水杨酸。该微生物群落由一种硫酸盐还原菌、三种产甲烷菌和一种发酵菌组成，无法将芳香环矿化。
