methanosarcina การใช้

• It is also present in some anaerobic microorganisms, such as " Methanosarcina barkeri ".
• "Methanosarcina " has been used in waste water treatment since the mid-1980s.
• "Methanosarcina " are the world's most diverse methanogens in terms of ecology.
• This chromophore can be purified from membranes of methanogenic archaea such as " Methanosarcina mazei ".
• A second type of archaeal cell wall is found in " Methanosarcina " and " Halococcus ".
• "Methanosarcina " cell membranes are made of relatively short lipids, primarily of C25 hydrocarbons and C20 ethers.
• Recently researchers have proposed an evolution hypothesis for acetate kinase and phosphoacetyl transferase with genomic evidence from " Methanosarcina ".
• Researchers have sought ways to utilize " Methanosarcina's " methane-producing abilities more broadly as an alternative power source.
• The enzyme methanosarcina-phenazine hydrogenase ( EC 1.12.98.3 ) has the name methanophenazine hydrogenase as a synonym.
• Only " M . acetivorans " and microbes in the genus " Methanosarcina " use all three known metabolic pathways for methanogenesis.
• ""'Methanosarcina " "'is a genus of anaerobic methanogens that produce methane using all three metabolic pathways for methanogenesis.
• Ftr from the mesophilic methanogen " Methanosarcina barkeri " and the sulphate-reducing archaeon " Archaeoglobus fulgidus " have a similar structure.
• Species of " Methanosarcina " are also noted for unusually large genomes . " M . acetivorans " has the largest known genome of any archaeon.
• However, " Methanosarcina barkeri " is exceptional in possessing a superoxide dismutase ( SOD ) enzyme, and may survive longer than the others in the presence of O 2.
• According to a theory published in 2014, " Methanosarcina " may have been largely responsible for the worst extinction event in the Earth's history, the Permian Triassic extinction event.
• The scientists concluded that these new genes, combined with widely available organic carbon deposits in the ocean and a plentiful supply of nickel, allowed " Methanosarcina " populations to increase dramatically.
• The presence of an S-layer in a member of the Methanosarcinales was determined in the 1980s by electron microscope ( EM ) studies examining the cell morphology of " Methanosarcina mazei ".
• A recent hypothesis put forward is that the volcanism was a trigger that led to an explosion of the growth of " Methanosarcina ", a microbe that then spewed enormous amounts of methane into Earth's atmosphere.
• The microbe theory suggests that volcanic activity played a different role-supplying the nickel which " Methanosarcina " required as a Siberian volcanic activity was a catalyst for, but not the primary cause of the mass extinction.
• ""'Methanosarcina acetivorans " "'is a versatile methane producing microbe which is found in such diverse environments as oil wells, trash dumps, deep-sea hydrothermal vents, and oxygen-depleted sediments beneath kelp beds.
