One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.

  • Media best suited for its growth are those that are inorganic and allow A. thiooxidans to use sulfur as a source of energy. (wikipedia.org)
  • A.s thiooxidans thrives at an optimum temperature of 28-30 °C. At lower temperatures (18 °C and below) and at 37 °C or higher, sulfur oxidation and growth are significantly slower, while temperatures between 55 and 60 °C are sufficient to kill the organism. (wikipedia.org)
  • Bicarbonate, however, is unnecessary because the CO2 from the atmosphere appears to be sufficient to support growth of A. thiooxidans, and would actually have an injurious effect in that it would tend to make the medium less acidic. (wikipedia.org)
  • A. thiooxidans requires only small amounts of nitrogen due to its small amount of growth, but the best sources are ammonimum salts of inorganic acids, especially sulfate, followed by the ammonium salts of organic acids, nitrates, asparagine, and amino acids. (wikipedia.org)
  • The growth of bacteria in extreme environments combined with their metal-reactive cell envelopes often results in their fossilization in these environments. (edu.au)
  • These bacteria have application for processing of copper-, uranium-, and precious metal-containing ore materials in the mining industry. (osumicrobiology.org)
  • 2006) where we demonstrated the role of bacteria in the supergene weathering of Fe and Cu at Morenci, AZ, the largest copper mine in North America, producing 1,000 tonnes of Cu/day through bacterial leaching. (edu.au)
  • 3 ) The dominant bacterial groups in constructed mine drainage wetland systems are aerobic, iron- and sulfur-oxidizing bacteria. (osumicrobiology.org)
  • Environmental transcriptome analysis reveals physiological differences between biofilm and planktonic modes of life of the iron oxidizing bacteria Leptospirillum spp. (biomedcentral.com)
  • In the Río Tinto (Spain), brown filaments develop under the water stream where the Gram-negative iron-oxidizing bacteria Leptospirillum spp. (biomedcentral.com)
  • During a study of natural marine bacteria populations, Zobell also discovered that there were many more microbes found attached to solid surfaces than were found in the surrounding medium [7]. (slideshare.net)
  • A. thiooxidans is a Gram-negative, rod-shaped bacterium with rounded ends that occurs in nature either as singlecells, as is the most common case, or sometimes in pairs, but rarely in triplets. (wikipedia.org)
  • Analysis of RNA-Seq data has also revealed differences in the expression pattern of 16 sRNAs according to the nitrogen source. (mdpi.com)
  • However, a large number of Acidithiobacillus strains and sequence clones have been obtained from a variety of ecological niches over the years, and many isolates are thought to vary in phenotypic properties and cognate genetic traits. (frontiersin.org)
