Query: NC_017167:1135137 Alicyclobacillus acidocaldarius subsp. acidocaldarius Tc-4-1
Lineage: Alicyclobacillus acidocaldarius; Alicyclobacillus; Alicyclobacillaceae; Bacillales; Firmicutes; Bacteria
General Information: Alicyclobacillus acidocaldarius, formerly Bacillus acidocaldarius was first isolated from an acidic creek in Yellowston National Park and grows at a pH of 3.6. This organism is both thermophilic and acidophilic and produces heat and acid stable enzymes, such as amylase and esterase, which may be important in industry.
Subject: NC_006177:12383 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.
