Query: NC_008686:1960034 Paracoccus denitrificans PD1222 chromosome 1, complete sequence
Lineage: Paracoccus denitrificans; Paracoccus; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria
General Information: This organism is commonly found in soil and sewage sludge. This organism is able to survive in both aerobic and anaerobic environments due to its ability to use both oxygen and nitrogenous oxides making it a popular model organism for the study of electron transfer and and energy conservation.
Subject: 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.
