Query: NC_009943:305854 Candidatus Desulfococcus oleovorans Hxd3, complete genome
Lineage: Desulfococcus oleovorans; Desulfococcus; Desulfobacteraceae; Desulfobacterales; Proteobacteria; Bacteria
General Information: An alkane-degrading sulfate-reducing Gram-negative bacterium isolated from the saline water phase of an oil-water separator from a northern German oil field. Desulfococcus oleovorans, originally designated Desulfobacterium oleovorans, was isolated using hexadecane as a carbon source and has been used to determine the mechanism of anaerobic hydrocarbon degradation.
Subject: NC_010337:2793667 Heliobacterium modesticaldum Ice1, complete genome
Lineage: Heliobacterium modesticaldum; Heliobacterium; Heliobacteriaceae; Clostridiales; Firmicutes; Bacteria
General Information: Heliobacterium modesticaldum strain Ice1, the type strain of this species, was isolated from Icelandic hot spring volcanic soils. It grows optimally above 50 degrees Celsius, grows best photoheterotrophically, but can grow in the dark chemotrophically on pyruvate. Phototrophic thermophile. This organism is an anoxygenic phototroph isolated from hot spring microbial mats and volcanic soil. Cell wall structure, the ability to form endospores, and 16S ribosomal RNA analysis place Heliobacterium modesticaldum in a family of phototrophic bacteria related to the Clostridia. Heliobacterium modesticaldum is able to fix nitrogen and may contribute significantly to the nitrogen availability in microbial mats.
