Methane Chemosynthesis

Methane Chemosynthesis-88
Using the lophotrochozoan tree as a reference, the time of divergence between B. philippinarum was estimated to be around 110.4 million years ago (Ma), with a 95% confidence interval of 52.4–209.7 Ma (Fig.2b), which is close to the upper age limit of deep-sea symbiotic mussels (102 Ma) previously estimated using five genes.1b) in the family Mytilidae using a whole-genome shotgun approach and compared their features ( Supplementary Note 1). The deep-sea and shallow-water mussel genome contained 96.3% and 93.7% complete and partial universal single-copy metazoan orthologous genes, respectively, indicating the completeness of the assembly and gene models ( Supplementary Note 6).

philippinarum, with substantial expansion and high expression levels of gene families that are related to immune recognition, endocytosis and caspase-mediated apoptosis in the gill, revealing presumed genetic adaptation of the deep-sea mussel to the presence of its chemoautotrophic endosymbionts.

    Other bacteria make organic matter by reducing sulfide or oxidizing methane. Our knowledge of chemosynthetic communities is relatively new, brought to light by ocean exploration when humans first observed a vent on the deep ocean floor in 1977 and found a thriving community where there was no light.…

  • Chemosynthesis - Wikipedia

    In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules usually carbon dioxide or methane and nutrients into organic matter using the oxidation of inorganic compounds e.g. hydrogen gas, hydrogen sulfide or methane as a source of energy, rather than sunlight, as in photosynthesis.…

    Chemosynthesis also takes place in more familiar places. For example, in the soil, nitrifying bacteria convert ammonia into nitrites and nitrates, while methane-generating archaea can be found in marshes and swamps, in sewage and in the intestines of mammals. Importance and Possible Uses…

  • Photosynthesis and chemosynthesis - Te Ara

    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.…
