chemoautotrophic การใช้

• Chemoautotrophic symbionts were presumed as a source of such carbon.
• Chemoautotrophic origin of the stable carbon isotope 13 C was confirmed experimentally.
• Members of the chemoautotrophic bacterial symbionts for their nutrition.
• Kane believes that chemoautotrophic bacteria like those in Movile Cave may have played key roles.
• Hydrogen sulphide produced by the " Barrow fault " may sustain this diverse community through chemoautotrophic energy production.
• The water from the hydrothermal vent is rich in dissolved minerals and supports a large population of chemoautotrophic bacteria.
• For this reason " H . volcanii " has a complex ion regulation system and is chemoautotrophic.
• Chemoautotrophic arsenite oxidizers ( CAO ) and heterotrophic arsenite oxidizers ( HAO ) convert As ( III ) into As ( V ).
• These marine worms are nutritionally dependent on their symbiotic chemoautotrophic bacteria lacking any digestive or excretory system ( no gut, mouth, or nephridia ).
• ""'Alkalilimnicola ehrlichii " "'is a species of arsenite-oxidizing haloalkaliphilic gammaproteobacterium capable of chemoautotrophic or heterotrophic growth.
• Finally, sulfophilic bacteria reduce the bones releasing hydrogen sulfide enabling the growth of chemoautotrophic organisms, which in turn, support organisms such as mussels, clams, limpets and sea snails.
• Finally, sulfophilic bacteria reduce the bones releasing hydrogen sulphide enabling the growth of chemoautotrophic organisms, which in turn, support other organisms such as mussels, clams, limpets, and sea snails.
• Moreover, the study of symbioses revealed associations with chemoautotrophic Bacteria, sulfur oxidizers in Vesicomyidae and Lucinidae bivalves and Siboglinidae tubeworms, and highlighted the exceptional diversity of Bacteria living in symbiosis with small Mytilidae.
• These results clearly point to additional modes of organic matter supply, including in situ chemoautotrophic production, within the OMZ . The denitrifying layer was also demonstrated to contain maxima in bacterial abundance and turbidity.
• Both systems share common characteristics such as the presence of reduced chemical compounds ( anoxia, a high abundance and metabolic activity of bacterial populations, and the production of autochthonous, organic material by chemoautotrophic bacteria.
• Although purple non-sulfur bacteria are normally photoheterotrophic, " R . palustris " can flexibly switch among any of the four modes of metabolism that support life : photoautotrophic, photoheterotrophic, chemoautotrophic and chemoheterotrophic.
• The theory thus sought to unify the " heterotrophic " theory of early evolution, where the primordial soup of simple molecules arose from non-biological processes, and the " chemoautotrophic " theory, where the earliest lifeforms created most simple molecules.
• In the absence of plants, urease activity in soil is generally attributed to heterotrophic microorganisms, although it has been demonstrated that some chemoautotrophic ammonium oxidizing bacteria are capable of growth on urea as a sole source of carbon, nitrogen, and energy.
• Others cluster round deep-sea hydrothermal vents where mineral-rich flows of water emerge, supporting communities whose primary producers are sulphide-oxidizing chemoautotrophic bacteria and whose consumers include specialized bivalves, sea anemones, barnacles, crabs, worms, and fish.
