Organohalide respiration by a Desulforhopalus-dominated community. An isolated Desulforhopalus-dominated consortium for organohalide respiration

In this study, we isolated a mutualistic consortium that is capable of reductive debromination of 2,6-DBP without adding external cobalamin, vitamin B12 (B12). Further genome-resolved analyses identified five novel bins, of which three were bearing RDase and TPh-RDase genes possibly involved in reductive debromination that was post-transcriptionally inhibited by acetylene. Metabolic pathway analysis confirmed that this consortium contains the complete de novo B12 biosynthesis pathway. Interestingly, further phylogenomic analyses suggested Marinifilum and Ancylomarina as new potential OHRB.
