Aerobic Biodegradation

Definitions

Aerobic Biodegradation - "The breakdown of organic contaminants by microorganisms when oxygen is present. Aerobic biodegradation also is known as aerobic respiration." - U.S. Geological Survey, 2010

Aerobic Biodegradation - "The degradation of compounds by microorganisms in the presence of oxygen. In aerobic biodegradation, microorganisms convert oxygen to water in the process of transforming other components to simpler products." - National Research Council, 1994

Aerobic Respiration - "Process whereby microorganisms use oxygen as an electron acceptor to generate energy." - National Research Council, 1993

Aerobic Respiration - "The process of destroying organic compounds with the aid of O₂ [oxygen] is called aerobic respiration. In aerobic respiration, microbes use O₂ to oxidize part of the carbon in the contaminant to carbon dioxide (CO₂), with the rest of the carbon used to produce new cell mass. In the process the O₂ gets reduced, producing water. Thus, the major byproducts of aerobic respiration are carbon dioxide, water, and an increased population of microorganisms." - National Research Council, 1993
