Query: NC_008618:1526392 Bifidobacterium adolescentis ATCC 15703, complete genome
Lineage: Bifidobacterium adolescentis; Bifidobacterium; Bifidobacteriaceae; Bifidobacteriales; Actinobacteria; Bacteria
General Information: Human gut bacterium. This species is a normal inhabitant of the healthy human gut. Newborns, especially those that are breast-fed, are colonized with Bifidobacteria within days after birth. This species was first isolated from the feces of a breast-fed infant. In one comprehensive 16S rDNA sequence-based enumeration of the colonic microbiota of three healthy adult humans it represents, on average, 0.008% of all 16S rDNA sequences and 4.302% of the sequences in its division (Eckburg et. They are saccharolytic organisms that produce acetic and lactic acids without generation of CO2, except during degradation of gluconate.
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.
