Query: NC_014614:2359046 Clostridium sticklandii, complete genome
Lineage: Clostridium sticklandii; Clostridium; unclassified Peptostreptococcaceae; Clostridiales; Firmicutes; Bacteria
General Information: This Clostridium (HF strain, ATCC 12662) was initially found associated with Methanococcus vannieli in formate-enriched cultures. After its isolation in pure culture, it was shown that this organism is capable of fermenting amino acids. Biochemical studies have shown that C. sticklandii obtains energy for growth from oxidation-reduction reactions between specific amino acid pairs. Clostridium sticklandii is a Gram-positive bacterium with low (G +C) content that is capable of fermenting amino acids.
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.
