Bottom Line: D. indicum belongs to the deep branching phylum of Chrysiogenetes, which currently only includes three other cultured species.Strain S5(T) is the type strain of the species and it is capable of growth using selenate, selenite, arsenate, nitrate or nitrite as terminal electron acceptors.The 2,928,377 bp genome encodes 2,619 proteins and 49 RNA genes, and the information gained from its sequence will be relevant to the elucidation of microbially-mediated transformations of arsenic and selenium, in addition to deepening our knowledge of the underrepresented phylum of Chrysiogenetes.

ABSTRACT
Desulfurispirillum indicum strain S5(T) is a strictly anaerobic bacterium isolated from river sediment in Chennai, India. D. indicum belongs to the deep branching phylum of Chrysiogenetes, which currently only includes three other cultured species. Strain S5(T) is the type strain of the species and it is capable of growth using selenate, selenite, arsenate, nitrate or nitrite as terminal electron acceptors. The 2,928,377 bp genome encodes 2,619 proteins and 49 RNA genes, and the information gained from its sequence will be relevant to the elucidation of microbially-mediated transformations of arsenic and selenium, in addition to deepening our knowledge of the underrepresented phylum of Chrysiogenetes.

Mentions: D. indicum strain S5 can use nitrate, nitrite, arsenate or selenate as the terminal electron acceptors for growth, while using the electron donors acetate, lactate or pyruvate [12,33]. The inspection of the strain S5 genome has confirmed the physiological data, and furthermore has enabled the discovery of sequences encoding other DMSO-like terminal reductases, as well as enzymes for the oxidation of additional electron donors ( [33] and Fig. 3). The discovery of such sequences suggests that the respiratory capabilities of strain S5 are broader than expected, and allows us to formulate hypotheses on further substrates and TEAs to be tested. In particular, we are interested in the dissimilatory reduction of selenium and arsenic oxyanions. Although the reduction of selenium is an important mode of respiration, the genes responsible for this process remain largely uncharacterized and virtually nothing is known about their regulation, or their interactions with other respiratory pathways.
