Dehalococcoides + Vinyl Chloride reductase

With our Dehalococcoides + Vinyl Chloride analysis micro-organisms and key parameters are determined that give you insight into the potential for complete biodegradation of PCE and TRI into ethene and ethane compounds. On request we can give you advice on stimulating and managing Dehalococcoides for your specific situation.

Analysis essentials

  • To establish the capacity for natural and complete degradation of chlorinated ethenes for your location
  • To determine the spread of micro-organisms that completely degrade chlorinated ethenes in groundwater
  • To monitor the potential for complete microbial reduction of chlorinated ethenes in time (does it increase or decrease?)

Content of the package

The following micro-organisms and key parameters are detected and quantified with our Dehalococcoides + Vinyl Chloride analysis:

  • The anaerobic microbial species Dehalococcoides spp. strains TM-EtOH, WL, JN18_V12_B, KM-2005, H10, BAV1, FL2, and CBDB
  • The anaerobic microbial species Dehalococcoides ethenogenes
  • Two genes specific for the anaerobic degradation of VC (vinyl chloride reductase)

Background information

CVOC (Chlorinated Volatile Organic Carbons) like PCE (polychloroethene) and TCE (trichloroethene) have many applications, especially as a solvent or degreaser. Because they were frequently used in the past, many sites are contaminated with these compounds. Under strictly anaerobic conditions the bacterium Dehalococcoides is the only species of bacteria that completely converts PCE and TCE to harmless end products ethene and ethane. Partial degradation of the components is not desirable, because these intermediate products cis-DCE (dichloroethene) and VC (vinyl chloride) have carcinogenic properties. The Dehalococcoides bacteria which contain the gene ‘vinyl chloride reductase’ are capable of complete and efficient degradation of vinyl chloride into ethene. However, not all Dehalococcoides bacteria contain the gene ' vinyl chloride reductase ' which can result in unwanted partial degradation. With our Dehaloccoides + Vinyl Chloride package the amount of Dehalococcoides is established as well as the amount of ‘vinyl chloride reductase’ genes. This enables you to determine with more certainty if the breakdown of PER and TRI will completely and effectively occur without the accumulation of the intermediate vinyl chloride.
