Query: NC_007677:117625 Salinibacter ruber DSM 13855, complete genome
Lineage: Salinibacter ruber; Salinibacter; Rhodothermaceae; Bacteroidetes Order II; Bacteroidetes; Bacteria
General Information: This organism is an extremely halophilic aerobe originally isolated from saltern crystallizer ponds in Spain. These bacteria can coexist in significant colonies with halophilic archaea under saline conditions. In contrast to other bacteria they do not regulate their intracellular salt conditions through proton pumps, but instead their protein makeup has adapted to be functional under high ionic conditions.
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.
