With our BTEXN analysis microbial key parameters for BTEXN degradation are determined, giving you insight into the potential for biodegradation of BTEXN compounds. On request we can give you advice on stimulating and managing BTEXN biodegradation processes in your specific situation.

Analysis essentials

  • To establish the capacity for natural degradation of BTEXN for your location
  • To determine the spread of anaerobic BTEXN degrading micro-organisms in groundwater
  • To monitor the potential for microbial BTEXN reduction in time (does it increase or decrease?)

Content of the package

The following microbial key parameter are detected and quantified with our BTEXN analysis:

  • A gene specific for the initial step in the degradation of toluene and xylene (benzylsuccinate synthase)
  • A gene specific for the initial step in the degradation of ethylbenzene (ethylbenzene dehydrogenase)
  • A gene specific for the degradation of the common metabolic intermediate benzoyl-CoA (benzyl-CoA reductase)
  • A gene specific for the hydrolytic aromatic-ring cleavage (oxoacyl-CoA hydrolase)
  • A gene specific for the degradation of naphthalene (naphthoyl-CoA reductase)

Background information

Many contaminated sites in the Netherlands contain the compounds BTEXN (benzene, toluene, ethylbenzene, xylene and naphthalene). BTEXN contaminations typically occur near gas and petroleum production sites, petrol stations and near gasoline storage tanks. These aromatic hydrocarbons are degradable biologically under aerobic as well as anaerobic conditions. Microbial key parameters are known which play a vital role in the anaerobic biologically degradation of BTEXN. With our BTEXN package these key parameters are detected and quantified, resulting in a fast and effective tool to gain insight into the degradation potency of the contaminated location.
