Microbiological Decontamination of Soils and Minerals
Microbiological remediation processes harness the ability of microorganisms to convert organic compounds into carbon dioxide, water, and biomass under optimized environmental conditions. This process is referred to as mineralization. Both aerobic and anaerobic biochemical processes are possible.
The functional decontamination of pollutants takes place under aerobic conditions and is primarily driven by bacteria and fungi. The breakdown of contaminants often occurs in parallel with the mineralization of organic matter. Complete pollutant degradation depends critically on their bioavailability in the soil and on optimizing the living conditions for the microorganisms.
Area of Application
1
Aliphatic Hydrocarbons such as Mineral Oils and Their Derivatives
4
Alicyclic Chlorinated Hydrocarbons and Their Derivatives
2
Monocyclic Aromatic and Heterocyclic Hydrocarbons (e.g., BTX Aromatics, Pyridine, Quinoline)
5
Volatile Halogenated and Chlorinated Hydrocarbons
(VHC and CHC)
3
Polycyclic Aromatic Hydrocarbons (Conditionally)
6
Occasionally Also Pesticides and Their Derivatives
General Basic Requirements for Microbiological Decontamination:
In order to apply microbiological remediation processes, precise knowledge of the substrate to be remediated is essential. In addition to biotic conditions, abiotic boundary conditions must also be examined.
-
Determination of microbial populations
-
Knowledge of the geochemical properties, genesis, soil type, and grain size distribution
-
Availability of energy and carbon sources for the contaminants
-
Abiotic factors: moisture, oxygen, pH value, nutrient availability, and temperature
-
Bioavailability of the contaminants
These investigations should be carried out prior to any microbiological remediation. For example, high salt content or the presence of heavy metals can have ecotoxic effects on the microbial communities and prevent successful remediation.
