    • Partner bacteria of the methanogenic archea therefore process these products.
    • Methanogenic archea bacteria can also form associations with other organisms.

  • The Sulfur Cycle

    • The most well known sulfur reducing bacteria are those in the domain Archea, which are some of the oldest forms of life on Earth.
