Query: NC_009997:3483157 Shewanella baltica OS195, complete genome
Lineage: Shewanella baltica; Shewanella; Shewanellaceae; Alteromonadales; Proteobacteria; Bacteria
General Information: This strain was isolated from the Baltic Sea. A psychrophilic bacterium. This genus includes species that inhabit a wide range of environments and are capable of utilizing a wide variety of electron acceptors during anaerobic respiration including some insoluble metal oxides while using very few carbon sources such as lactate or acetate. This group of organisms have been studied extensively for their electron transport systems. This species is differentiated from other Shewanella spp. based on its ability to grow at 4 degrees C but not at 37, production of N-acetyl-beta-glucosaminidase, lack of chymotrypsin, and ability to use a variety of complex carbon compounds as carbon and energy sources.
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.
