biodegradation 中文解釋 wordnet sense Collocation Usage Collins Definition
  1. (biodegrade) break down naturally through the action of biological agents; "Plastic bottles do not biodegrade"
  2. Biodegradation is the chemical breakdown of materials by a physiological environment. The term is often used in relation to ecology, waste management and environmental remediation (bioremediation). Organic material can be degraded aerobically with oxygen, or anaerobically, without oxygen. ...
  3. (biodegraded) Subject to biodegradation
  4. (Biodegrading) A process in which a substance or material can be broken down into simpler compounds by microorganisms and other decomposers such as fungi.
  5. Biodegradation is the process whereby organic chemicals are broken down into progressively simpler molecules, largely by the action of various bacteria.
  6. Decomposition of material by microorganisms.
  7. The metabolic breakdown of materials into simpler components by living organisms.
  8. decomposition of certain substances (in particular hydrocarbons) by living organisms.
  9. The breaking down of substances by microorganisms, such as oil-hungry Alcanivorax, which use the substances for food and generally release harmless byproducts such as carbon dioxide and water.
  10. Decomposition or breakdown of a substance through the action of microorganisms (such as bacteria or fungi) or other natural physical processes (such as sunlight).
  11. The conversion or breakdown of the chemical structure of a pesticide by or in organisms. See also Degradation and Mineralisation.
  12. The chemical breakdown of materials under natural conditions.
  13. the breakdown of a material mediated by a biological system [5870]; the passive response of a material to the physico-chemical conditions found in living systems, involving actual cellular effects on the pericellular environment [234].
  14. The breakdown by living organisms of a compound to its chemical constituents. Materials that can be easily biodegraded are colloquially termed biodegradable.
  15. Changes caused by micro-organisms (bacteria, algae, fungi): viscosity loss, odor spoilage, delamination, discoloration...
  16. The destruction or organic materials by microorganisms, soils, natural bodies of water or wastewater treatment systems.
  17. The breakdown of putrescible (organic) material by biological processes.
  18. The breakdown of a complex chemical through biological processes that can result in minor loss of functional groups, fragmentation into larger constitutents, or complete breakdown to carbon dioxide and minerals. ...
  19. The breaking down of a chemical by organisms in the environment.
  20. Decomposition by microbial action, as with some detergents.
  21. [Greek bios – life and French degradation] – changes of structure, quality of materials or objects under the influence of biological agents: usually it means loss of basic (useful) characteristics.
  22. is the complete biochemical decomposition of organic molecules by microorganisms.Biodegradability reduces a substance being emitted into the environment or a substance being retained by it. ...
