Examples of halophile in the following topics:

  • Extremely Halophilic Archaea

    • Halophiles are extremophiles that thrive in environments with very high concentrations of salt.
    • Halophiles are extremophiles that thrive in environments with very high concentrations of salt.
    • In fact, the very name "halophile" comes from the Greek word for "salt-loving. " Although some halophilic bacteria and eukaryotes exist, the largest classification of halophiles is in the Archaea domain.
    • Halophiles prevent this loss of water by increasing the internal osmolarity of the cell.
    • Describe the methods employed by halophilic Archaea to prevent water loss
  • Nonthermophilic Crenarchaeota

    • Nonthermophilic Crenarchaeota can be extreme halophiles living in highly salty environments.
    • Crenarchaeota can be extreme halophiles, and include organisms living in highly salty environments (for example, halococcus).
    • Halococcus is a genus of extremely halophilic archaea , meaning that they require high salt levels, sometimes as high as 32% NaCl, for optimal growth.
    • Halophiles are found mainly in inland bodies of water with high salinity, where their pigments (from a protein called rhodopsinprotein) tint the sediment bright colors.
    • Because they can function under such high-salt conditions, Halococcus and similar halophilic organisms have been utilized economically in the food industry and even in skin-care production.
  • Viruses of Archaea

    • One group is exemplified by the Halorubrum pleomorphic virus 1 ("Pleolipoviridae") infecting halophilic archaea and the other one by the Aeropyrum coil-shaped virus.
    • Species of the genus Salterprovirus infect halophilic archaea species of the Euryarchaeota.
  • The Energetics of Chemolithotrophy

    • Chemoautotrophs generally fall into several groups: methanogens, halophiles, sulfur oxidizers and reducers, nitrifiers, anammox bacteria, and thermoacidophiles.
  • Habitats and Energy Metabolism of Crenarchaeota

    • Nonetheless, they are a useful starting point for classification Halophiles live in extremely saline environments such as salt lakes.
  • Archaeal Gene Regulation

    • One group is exemplified by the Halorubrum pleomorphic virus 1 ("Pleolipoviridae") infecting halophilic archaea and the other one by the Aeropyrum coil-shaped virus ("Spiraviridae") infecting a hyperthermophilic (optimal growth at 90-95°C) host.
  • Types of Microorganisms

    • Based on their habitat, all Archaeans can be divided into the following groups: methanogens (methane-producing organisms), halophiles (archaeans that live in salty environments), thermophiles (archaeans that live at extremely hot temperatures), and psychrophiles (cold-temperature Archaeans).
  • Nongenetic Categories for Medicine and Ecology

    • Halophile: an organism requiring at least 0.2M concentrations of salt (NaCl) for growth
