Query: NC_009718:799431 Fervidobacterium nodosum Rt17-B1, complete genome
Lineage: Fervidobacterium nodosum; Fervidobacterium; Thermotogaceae; Thermotogales; Thermotogae; Bacteria
General Information: Fervidobacterium nodosum is a thermophilic, Gram-negative, motile, non-sporulating, glycolytic, obligately anaerobic rod that exists singly, in pairs or in chains. Fervidobacterium nodosum was isolated from a hot spring in New Zealand. Its optimal growth temperature is 65 to 70 degrees Celsius. The cellular morphology of this organism, a member of the Thermotogales, is characterized by a terminal spherical extension of the cell envelope.
Subject: NC_007722:55558 Erythrobacter litoralis HTCC2594, complete genome
Lineage: Erythrobacter litoralis; Erythrobacter; Erythrobacteraceae; Sphingomonadales; Proteobacteria; Bacteria
General Information: This strain was collected from the Sargasso Sea at a depth of 10 meters. Phototrophic bacterium. Organisms in this aerobic phototrophic genus are found in marine environments. Members of this group produce bacteriochlorophyll a, which is normally found in anaerobic organisms. One theory to explain this is that the anoxygenic photosynthetic gene cluster was acquired by these organisms via lateral gene transfer. Although they require an organic carbon substrate for growth, they are able to supplement a significant fraction of their metabolic requirements with photosynthetically derviced energy. This species was isolated from a marine cyanobacterial mat. Although they require an organic carbon substrate for growth, they are able to supplement a significant fraction of their metabolic requirements with photosynthetically derviced energy. The presence of the carotenoids bacteriorubixanthinal and erythroxanthin sulfate give this organism a reddish color.
