Query: NC_007520:2128178 Thiomicrospira crunogena XCL-2, complete genome
Lineage: Thiomicrospira crunogena; Thiomicrospira; Piscirickettsiaceae; Thiotrichales; Proteobacteria; Bacteria
General Information: This organism is a colorless sulfur-oxidizing bacterium isolated from a deep-sea hydrothermal vent. Sulfur-oxidizing bacterium. Thiomicrospira crunogena is a chemoautotroph commonly isolated from deep sea and shallow-water hydrothermal vents. This organism uses the oxidation of reduced sulfur compounds (thiosulfate, sulfide and sulfur) to generate the energy necessary to fix carbon and plays an important role in the cycling of sulfur in the marine environment.
Subject: NC_010337:2339056 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.
