Query: NC_000853:771746 Thermotoga maritima MSB8, complete genome
Lineage: Thermotoga maritima; Thermotoga; Thermotogaceae; Thermotogales; Thermotogae; Bacteria
General Information: Rod-shaped thermophilic marine bacterium that metabolizes many simple and complex carbohydrates including glucose, sucrose, starch, cellulose, and xylan. This hyperthermophilic organism was originally isolated from a geothermal marine area near Vulcano, Italy. Thermotoga maritima is a hyperthermophile with an optimum growth temperature of 80 degrees C. This organism, a member of the Thermotogales, has the characteristic sheath-like envelope which extends beyond the cell wall. These organisms are heterotrophs are able to use a wide range of carbohydrates.
Subject: NC_010337:565730 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.
