Complete genome sequence of Desulfobulbus propionicus type strain (1pr3T)

Abstract

Desulfobulbus propionicus Widdel 1981 is the type species of the genus Desulfobulbus, which belongs to the family Desulfobulbaceae. The species is of interest because of its great implication in the sulfur cycle in aquatic sediments, its large substrate spectrum and a broad versatility in using various fermentation pathways. The species was the first example of a pure culture known to disproportionate elemental sulfur to sulfate and sulfide. This is the first completed genome sequence of a member of the genus Desulfobulbus and the third published genome sequence from a member of the family Desulfobulbaceae. The 3,851,869 bp long genome with its 3,351 protein-coding and 57 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

Sulfate reduction with electrons directly derived from electrodes in bioelectrochemical systems

“…Geobacter species were well known for the capacity to directly accept electrons from polarized electrode [19] and distributed sparsely on electrode surface in short rod-shaped [5,7]. The sequence of band A-6 was 100% similar to that of Desulfobulbus propionicus, which was ellipse-shaped bacteria [20] and could grow via electron transfer to electrodes [21]. The results from DGGE and the observation with SEM suggested that the corresponding bacterium were responsible for sulfate reduction using electrons from negatively poised electrode.…”

The Family Desulfobulbaceae

“…For the type strain of Desulfobulbus propionicus DSM 2032, the genome is 3,881,859 bp long and contains 3,408 genes with 3,351 coding for protein and 57 RNA genes (Paganini et al 2011). The mol% G+C of the DNA is 58.93.…”

On the role, ecology, phylogeny, and structure of dual-family immunophilins

“…They are also capable of mixotrophic growth, i.e., simultaneous utilization of H 2 and organic substrates. As its name implies, Desulfobulbus propionicus is able to disproportionate elemental sulfur to sulfate and sulfide and is of great environmental and industrial interest not only due to its impact on the sulfur cycle in aquatic sediments but also its large substrate spectrum and a broad versatility in using various fermentation pathways (Pagani et al 2011). …”
