Query: 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.

General Information: This strain was isolated from a sample of coastal sea water near a French Antarctic station. This organism is adapted to growth at low temperatures and reactive oxygen species by a number of putative dioxygenases and fatty acid desaturases amongst other proteins. The organism can grow optimally in salt concentrations of 1.5 to 3.5% NaCl.The genome consists of 2 chromosomes, one of which may replicate unidirectionally. Some interesting features of this genome include the lack of the nucleoid-associated gene hns, a lack of genes involved in molybdopterin metabolism, a lack of the cAMP-CAP complex, and a lack of the PEP-dependent PTS system.
