Based on decades of research, the scientific community has identified microbes that degrade a wide range of contaminants. Combined with increases in knowledge of biodegradation pathways, rapid and profound advances in genomics and molecular biological tools underpin bioremediation and include next-generation sequencing (Gene-Trac® NGS) and multi-target tests (Gene-Trac® Digital Arrays). Such tests are now routinely used by Remediation Site Managers to better understand conditions at contaminated sites.
- Molecular biological tools allow us to better understand and use the following characteristics of microbial communities to support biodegradation of contaminants:
- Their ability to degrade chlorinated solvents and hydrocarbons under aerobic and anaerobic conditions
- Whether communities can degrade the high contaminant concentrations often found in DNAPL source zones
- Whether communities can overcome toxic inhibition by co-contaminants
- Their ability to create and capture essential nutrients such as vitamin B12 and nitrogen
Thanks to decades of advances, we can monitor a wide range of microbial pathways using molecular biological tools. The resulting information provides a critical line of evidence for monitored natural attenuation and can also be used to optimize enhanced bioremediation and create best-value solutions.
This presentation will focus on how attendees can gain a better understanding of microbial communities at contaminated sites and how they can use this knowledge to reach cleanup goals as quickly and cost-effectively as possible.
SiREM’s webinar series features speakers who are subject matter experts to provide the latest information on technology advances in environmental remediation and site characterization. The webinars will combine recent research and development activities for new and emerging contaminants and technologies with real world applications to characterize and remediate contaminated sites.
