Gene-Trac® testing is used to quantify key microorganisms and functional genes for the assessment of bioremediation potential and to monitor enhanced bioremediation performance. Several tests are available for quantifying and characterizing microorganisms and their respective functional genes in groundwater and soil/sediment from contaminated sites.
Use Gene-Trac® Testing to:
- Determine if suitable microorganisms are present for MNA remedies.
- Predict the effectiveness of biostimulation before the addition of electron donor.
- Determine the need for bioaugmentation.
- Determine the impact of site amendments including, electron donors/acceptors.
- Predict if intermediates such as cDCE or vinyl chloride are likely to accumulate.
- Characterize microbial community spatial and temporal variability.
- Validate the performance of enhanced bioremediation projects.
- Make informed decisions to manage bioremediation and other microbial systems.
Quantify Environmental Microorganisms and Microbial Communities
SiREM offers a growing number of targets for Gene-Trac® that uses quantitative polymerase chain reaction (qPCR) testing to quantify the key bacteria and functional genes that includes: Dehalococcoides (Dhc), Dehalobacter (Dhb) and Dehalogenimonas (Dhg), Desulfitobacterium (Dsb), Geobacter (Geo) and key functional genes such as vinyl chloride reductase (vcrA, bvcA), trichloroethene reductase (tceA), chloroform, 1,1,1-TCA and 1,1-DCA reductase (cfrA/dcrA). These microorganisms and functional genes are critical to reductive dechlorination of many chlorinated compounds, including chlorinated ethenes, ethanes, methanes, and propanes. Geobacter and sulfate reducers play key roles in the metabolism of aromatic hydrocarbon compounds and the generation of iron sulfur compounds critical to natural attenuation remedies. The dxmB and ALDH genes are important in the aerobic degradation of 1,4-dioxane. A full suite of tests are also available for both aerobic and anaerobic BTEX degrading organisms. Refer to the pdf document for the comprehensive list of Gene-Trac® tests that are available.
Gene-Trac® Next Generation Sequencing (NGS)
Gene-Trac® NGS provides detailed microbial community composition to better understand the current and potential functions of microbial communities. Gene-Trac® NGS provides a non-targeted cost-effective insight into community function and dynamics to gain insight into complex microbial systems including bioremediation sites, wastewater treatment systems and landfills.
