Define 'BIOAUGMENTATION' in brief
Answers
Answer:
Bioaugmentation is the practice of adding cultured microorganisms into the subsurface for the purpose of biodegrading specific soil and groundwater contaminants.
Explanation:
Bioaugmentation for Chlorinated Contaminants
In many cases, cultured microorganisms used for bioaugmentation are “specialists” in degrading specific target contaminants. For example, some microbes may be able to degrade the chlorinated compounds cis-1,2 dichloroethylene (cDCE) and vinyl chloride (VC) more quickly than the naturally-occurring microbial community at a particular site. As a result, the remediation community has shifted toward a more prescriptive approach with the use of bioaugmentation to accelerate the reductive dechlorination process, achieve remediation targets, and realize cost savings.
Specific strains of anaerobic microorganisms have been isolated, cultured and are commercially available for the biodegradation of the chlorinated contaminants cDCE and VC. Bio-Dechlor INOCULUM® Plus is a widely used bioaugmentation culture designed specifically for this purpose. It is typically co-applied with electron donor solutions such as 3-D Microemulsion® and HRC® to facilitate full and rapid reductive dechlorination.
Bioaugmentation for Petroleum Hydrocarbons
Relative to bioaugmentation for the degradation of petroleum hydrocarbons or any aerobically degradable contaminants in soil and groundwater, it is rare if ever that aerobic degrader augmentation is required to facilitate enhanced aerobic biodegradation.
