Query: NC_012962:3864000 Photorhabdus asymbiotica, complete genome

Lineage: Photorhabdus asymbiotica; Photorhabdus; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria

General Information: This strain is a North American clinical isolate from human blood. Photorhabdus asymbiota, formerly Xenorhabdus luminescens, has been isolated from human wound and blood infections often in association with spider bites. This species can also be isolated from the entomopathogenic nematode Heterorhabditis indica. Photorhabdus asymbiota is divided into two subspecies, subsp. australis which contains the Australian clinical isolates and subsp. asymbiota which contains the North American isolates. Photorhabdus is currently subdivided into three species, luminescens, temperate and asymbiotica all of which have been isolated as symbionts of heterorhabditid nematodes. This organism is unusual in that it is symbiotic within one insect, and pathogenic in another, the only organism that is known to exhibit this dual phenotype.

Subject: NC_011901:3072817 Thioalkalivibrio sulfidophilus HL-EbGr7 chromosome, complete

Lineage: Thioalkalivibrio sulfidophilus; Thioalkalivibrio; Ectothiorhodospiraceae; Chromatiales; Proteobacteria; Bacteria

General Information: Obligately chemolithoautotrophic, haloalkaliphilic, mesophilic, microaerophilic and sulfur-oxidizing bacterium. Uses CO2 as a carbon source and reduced inorganic sulfur compounds as an energy source. Utilizes ammonium and urea, but not nitrate or nitrite, as a N-source. Isolated from a full-scale Thiopaq bioreactor in the Netherlands used to remove H2S from biogas. Thioalkalivibrio species are commonly isolated from soda lakes and tend to dominate the microbial community of hypersaline soda lakes. These organisms have a pH optimum of 10 and are able to oxidize hydrogen sulfide to elemental sulfur. Thioalkalivibrio species have also been isolated from sulfide oxidizing bioreactors which remove sulfide from refinery and natural gas.
