show Abstracthide AbstractDesulfovibrio alkalitolerans DSM 16529 is a weak methylator of mercury relative to most other d - Proteobacteria of the Desulfovibrionales despite sharing 97% sequence similarity in the 16S rRNA gene with Desulfovibrio isolate X2, a very strong methylator of Hg. We present the genome sequence of Desulfovibrio alkalitolerans DSM 16529 as a resource for evaluation of genetic elements associated with the ability of bacterial to methylate mercury.
