Methane Chemosynthesis

Methane Chemosynthesis-33
Despite this hostile environment, these ecosystems support dense populations of macrobenthos which, with the help of chemoautotrophic endosymbionts, are fuelled by simple reduced molecules such as methane and hydrogen sulfide.Deep-sea mussels (Mytilidae, Bathymodiolinae) often dominate at hydrothermal vents and cold seeps around the world.

3a), potentially owing to recurrent population bottlenecks as a result of population extinction and re-colonizationa,b, Shell of the deep-sea mussel B.

platifrons (a, 10.7 cm) and shallow-water mussel M. c, Phylogenetic tree of 11 lophotrochozoan species based on genome data; the value of bootstrap support is shown at each node.

c, Heat map of major annotated Pfam domains that are expanded in B.

platifrons, with multiple domains in a given gene being counted as one.

Phylogenetic analysis shows that these mussel species diverged approximately 110.4 million years ago.

Many gene families, especially those for stabilizing protein structures and removing toxic substances from cells, are highly expanded in B.

Our study of the genomic composition allowing symbiosis in extremophile molluscs gives wider insights into the mechanisms of symbiosis in other organisms such as deep-sea tubeworms and giant clams.

The environment of deep-sea hydrothermal vents and methane seeps is characterized by darkness, lack of photosynthesis-derived nutrients, high hydrostatic pressure, variable temperatures and high concentrations of heavy metals and other toxic substances.

A follow-up metaproteomic analysis of the gill of B.

platifrons shows methanotrophy, assimilatory sulfate reduction and ammonia metabolic pathways in the symbionts, providing energy and nutrients, which allow the host to thrive.

    Chemosynthesis allows organisms to live without using the energy of sunlight or relying on other organisms for food. Like chemosynthesis, it allows living things to make more of themselves. By turning inorganic molecules into organic molecules, the processes of chemosynthesis turn nonliving matter into living matter.…

    Chemosynthesis occurs around hydrothermal vents and methane seeps in the deep sea where sunlight is absent. During chemosynthesis, bacteria living on the sea floor or within animals use energy stored in the chemical bonds of hydrogen sulfide and methane to make glucose from water and carbon dioxide dissolved in sea water.…
