Query: NC_006177:835459 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.
Subject: NC_012483:483425 Acidobacterium capsulatum ATCC 51196, complete genome
Lineage: Acidobacterium capsulatum; Acidobacterium; Acidobacteriaceae; Acidobacteriales; Acidobacteria; Bacteria
General Information: Isolated from acidic mine drainage in Yanahara mine, Okayama, Japan. Acidophilic bacterium. This genus comprises a number of species commonly found in water reservoirs, microbial mats, many different soil types, marine and freshwater sediments, as well as in hot-spring mats and sediments, etc. Furthermore, they sometimes form the dominant group in a habitat. These bacteria are involved in the first step of destruction of biologically complex molecules produced by autotrophic (capable of synthesizing their own nutrients) microorganisms. Acidobacterium capsulatum is an aerobic, mesophilic, chemo-organotroph able to use a variety of carbon sources and to grow up to pH 6.0. The species comprises several strains characterized by orange pigmentation, production of menoquinones as their sole quinones, and branched-chain iso fatty acids as their cell envelope components.
