Query: NC_007644:1638083 Moorella thermoacetica ATCC 39073, complete genome
Lineage: Moorella thermoacetica; Moorella; Thermoanaerobacteraceae; Thermoanaerobacterales; Firmicutes; Bacteria
General Information: Moorella thermoacetica, formerly Clostridium thermoaceticum, can grow on hydrogen and fix carbon dioxide or carbon monoxide with the production of acetate. It is found at the bottom of stagnant ponds and forms extremely heat-resistant spores.
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.
