Abstract
The draft genome of a member of the bacterial family Desulfobulbaceae (phylum Deltaproteobacteria) was assembled from the metagenome of a sulfidogenic [13C6]toluene-degrading enrichment culture. The “Desulfobulbaceae bacterium Tol-SR” genome is distinguished from related, previously sequenced genomes by suites of genes associated with anaerobic toluene metabolism, including bss, bbs, and bam.
Highlights
The draft genome of a member of the bacterial family Desulfobulbaceae was assembled from the metagenome of a sulfidogenic [13C6]toluene-degrading enrichment culture
Recent DNA-stable isotope probing (DNA-SIP) of sulfidogenic microcosms and enrichment cultures revealed bacteria related to Desulfocapsa to be key toluene-degrading organisms [6,7,8,9], few hydrocarbon-degrading Desulfobulbaceae have been cultivated
We provide the draft genome of an uncultivated Desulfobulbaceae member that is implicated in toluene degradation under sulfidogenic conditions and contains genes associated with anaerobic hydrocarbon metabolism
Summary
The draft genome of a member of the bacterial family Desulfobulbaceae (phylum Deltaproteobacteria) was assembled from the metagenome of a sulfidogenic [13C6]toluene-degrading enrichment culture. Recent DNA-stable isotope probing (DNA-SIP) of sulfidogenic microcosms and enrichment cultures revealed bacteria related to Desulfocapsa to be key toluene-degrading organisms [6,7,8,9], few hydrocarbon-degrading Desulfobulbaceae have been cultivated. Complete genome sequences are available for only four Desulfobulbaceae: Desulfobulbus propionicus DSM 2032T [10], Desulfocapsa sulfexigens DSM 10523 [11], Desulfotalea psychrophila LSv54 [12], and Desulfurivibrio alkaliphilus AHT2 (ACYL01000000); plus eight draft Desulfobulbus genomes (http: //patricbrc.org).
