Biodegradation

IUPACDefinition of
Degradation caused by enzyme process resulting from the action of cells.


(break downIs caused by the result of enzymatic processes in cell activity)

Notes: Modified to exclude abiotic phenol processes.


(Note:Abiological enzymeChanged to exclude the process. )[1]

BiodegradationWhat is (biodegradation)?Bacteria,Fungi, The compound is decomposed into inorganic substances by other organisms.Almost all compounds are eventually biodegraded to inorganics, but it is time that matters.Factors related to their speed include the environment such as light, water, oxygen and temperature, and the substance itself is easily used by degrading bacteria (BioremediationIs high) and other factors[2][3].

Typical example of problems in biodegradation

Also called hard ABS detergent in the 1960s, it remains in wastewater without being biodegraded by microorganisms, killing soil bacteria, and causing problems in rivers and sewage treatment plants to be covered with bubbles, making sewage treatment difficult. Became[4].. In the 1970sLinear alkylbenzene sulfonate sodiumReplaced by (LAS)[5].

Biodegradability test

Biodegradability can be measured in a variety of ways[6].

  • Easy biodegradability
Many standard test methods for measuring the biodegradability of organic substances include OECD (OECD Test Guidelines 301A-F), EU (C.4 test), OPPTS (835.3110) and ISO (9408, 9439, 10707). Developed by the institution.
  • Intrinsic biodegradability
OECD Test Guidelines 302A-C, EU C.9 and C.12, and ASTM E 1625-94, etc.
  • Water system simulation test
ISO / DS14952 "Flask Shake Batch Test of Surface Water or Surface Water / Sediment Suspension" (Nyholm and Toräng, 1999), Biodegradable ASTM E 1279-89 (95) by Flask Shake Diary Test Method Test and similar OPPTS 835.3170 test
  • STP (sewage treatment) simulation test
OECD Test Guidelines 303A “Coupled Unit” test, ISO 11733 “Activated sludge simulation test”, EU C.10 test, etc.
  • Anaerobic degradability
ISO 11734: 1995 (E) exam, ASTM E 1196-92 exam, and OPPTS 835.3400 exam, etc.
  • Decomposition in soil and sediment
OECD Test Guidelines 304A Test, OPPTS 835.3300 Test
  • Japanese Industrial Standard
JIS K 6950, JIS K 6951, JIS K 6953, JIS K 6955
