Abstract:Reductive dehalogenation is crucial for halogen cycling and environmental remediation, yet its ecological role is incompletely understood, especially in deep-sea environments. To address this gap, we investigated the diversity of reductive dehalogenases (RDases) and ecophysiology of organohalide reducers in deep-sea cold seeps, which are environments rich in halogenated compounds. Through genome-resolved metagenomic analysis 165 global cold seep sediment samples, we identified four types of RDases, namely prot… Show more
