Biodegradation tests involve testing samples in response to various parameters: dilution, nutrient addition, pH, temperature, and others. The pattern of oxygen uptake in aerobic tests; nitrogen gas production in anoxic denitrification tests; methane production in methanogenic tests; hydrogen production during glycolysis; and carbon dioxide production during fermentation reactions gives a measure of the rate and extent of biodegradation of the organic constituents of the test sample.
Enhanced aerobic biodegradation is the practice of adding oxygen (an electron acceptor) to groundwater and/or soil to increase the number and vitality of indigenous microorganisms performing biodegradation.

Intrinsic kinetic tests involve adding relatively high concentrations of organic substrate to small concentration of acclimated microorganisms so that the COD/VSS ratio typically is greater than 10. Kinetic parameters are then determined by non-linear modeling using well-known relationships between biological growth and oxygen uptake.
BioSolve Pinkwater is used to accelerate natural bioremediation of contaminated soil either on site through surface application or on land farms through application to biopiles. When Pinkwater solution is sprayed onto and aggressively mixed into contaminated soil, hydrocarbons come in contact with the strongly “lipophilic” (oil loving) surfactant. Mimicking the process by which bacteria make hydrocarbons digestible, the surfactants “solubilize” contaminates, pulling them into an aqueous...
