Query: NC_014666:4419693 Frankia sp. EuI1c chromosome, complete genome
Lineage: Frankia; Frankia; Frankiaceae; Actinomycetales; Actinobacteria; Bacteria
General Information: Environment: Host, Plant symbiont, Soil; Temp: Mesophile. Frankia sp. EuI1c was isolated from the Autumn olive, Elaeagnus umbellata. Frankia sp. (strain EuI1c) is an aerobic Gram-positive bacterium isolated from four continents (North America, South America, Africa, and Asia) and different habitats, including dry soils with high salinity levels, steppe-like plains at 900 m, and mountain forests at 3,000 m.
Subject: NC_006177:2398482 Symbiobacterium thermophilum IAM 14863, complete genome
Lineage: Symbiobacterium thermophilum; Symbiobacterium; Shewanellaceae; Clostridiales; Firmicutes; Bacteria
General Information: This symbiotic and thermophilic bacterium was discovered by screening for thermostable tryptanophases in Japanese compost. Cultured growth of this organism requires the presence of another bacterial species, such as a Bacillus or Escherichia coli, which provides diffusable metabolites required for its growth. Pure cultures can be obtained by growing Symbiobacterium thermophilum in a bioreactor, separated from its symbiotic counterpart by a dialysis membrane. Because of its symbiotic nature, it cannot be cultured with conventional methods. Despite a negative reaction for gram stain, this species is placed with the gram-positive bacteria based on 16s phylogenetic analysis.
