Definition of biogenic in English:



  • attributive Produced or brought about by living organisms.

    ‘biogenic sediments’
    • ‘Some other possible mechanisms could include increased dust deposition, volatile biogenic emissions, or tectonic activity.’
    • ‘‘This demonstrates that looking for biogenic signatures alone will complicate the process of looking for life,’ he said.’
    • ‘These observations strongly implicate the synthesis and regulation of biogenic amines in regulating mating behavior and causing variation in mating behavior within and between species.’
    • ‘This would permit survival of an intermittent bottom-dwelling fauna whose activities would result in the mixing of the biogenic input to destroy any lamination.’
    • ‘Snake venoms are a complex mixture of proteins, polypeptides, biogenic amines, and other components that may have neurotoxic, hemostatic, and/or hemorrhagic effects on prey.’
    • ‘Slow transmission can take many minutes and is enormously more complex, involving at least 100 different chemicals falling into four classes: biogenic amines, peptides, amino acids and nitric oxide.’
    • ‘The monthly settling particulate samples provide a data set of seasonal and interannual export fluxes of organic carbon, biogenic opal, calcium carbonate, and lithogenic material.’
    • ‘It serves as a timely reminder that simple molecules, such as biogenic amines and many others, were not ‘invented’ by animals, but that their origin dates back long before the diversification of plant and animal evolutionary lineages.’
    • ‘This is due to the special biogenic amine in chocolate, which can change internal secretions.’
    • ‘Carbon occurs in marine sediments as organic carbon linked with metabolic processes of plants and animals, and as carbon contained within biogenic and abiogenic carbonate minerals.’
    • ‘Pelagic biogenic sediments consist of the fine-grained skeletal debris of marine planktonic and benthonic organisms.’
    • ‘He expanded this idea to the propose the ‘deep, hot biosphere’ which both generates methane and adds biogenic signatures to inorganic petroleum, and that part, at least, is looking more correct every year.’
    • ‘The European Space Agency will launch Mars Express in that year with a lander, Beagle - 2, with a scientific payload dedicated to detecting signs of biogenic activity on Mars.’
    • ‘Some of our results suggest that the extractable agent in nest soil is organic, and possibly biogenic.’
    • ‘In 1988, William Chameides of the Georgia Institute of Technology used Atlanta as a case study to show that the impact of such biogenic emissions from trees on urban ozone levels could be significant.’
    • ‘This topography is interpreted as formed by contour-parallel bottom currents, which caused erosion, transport and deposition of sediment drifts and ridges, and possibly also build-up of biogenic mounds.’
    • ‘In terms of biomass, organic carbon fixation, space occupation, and biogenic habitat, kelps are the dominant reef-inhabiting organisms in cool seas, especially in the Northern Hemisphere.’
    • ‘Given their consistent morphology, these structures are considered biogenic.’
    • ‘The methods of distinguishing biogenic from nonbiogenic carbon developed by van Zuilen and Lepland have helped support this new evidence and it has now gained widespread acceptance, Arrhenius said.’
    • ‘If intrinsic changes in biogenic amine neurochemistry occur because of winning or losing experiences, these changes may be reflected in the types of chemicals released into the urine of dominant and subordinate crayfish.’
