This white paper explains how sulfate reducing microorganisms contribute to oil reservoir souring and offers strategies for mitigating reservoir souring. Molecular biological tools like qPCR, next generation sequencing, and whole genome sequencing can be used to monitor microorganisms that are important for oil reservoir souring and souring mitigation.
Molecular biological tools offer innovative solutions for monitoring microbial communities that play essential roles in wastewater treatment. This white paper explores how qPCR, next generation sequencing, and whole genome sequencing can be used to monitor microorganisms that are important for anaerobic digester management, nitrogen cycling, enhanced biological phosphorus removal, bulking and foaming, and microbial source…
This handout describes how microbial monitoring at sites impacted with 1,4-dioxane can help identify biodegradation potential, support remediation design, and improve regulatory compliance and risk assessment. Microbial analyses that support 1,4-dioxane bioremediation projects include CENSUS® qPCR, stable isotope probing, and whole genome sequencing.
This handout covers how microbial monitoring can help optimize anaerobic digester performance for maximum efficiency and reliability. Advanced monitoring solutions include CENSUS®, QuantArray®-BGC, next generation sequencing, and whole genome sequencing.
This paper provides an overview of microorganisms involved in bioscale production and dissolution, which can cause issues in a variety of industries, including oil and gas, mining, and industrial heating systems. It also highlights how molecular biological tools such as qPCR (CENSUS®), next generation sequencing and whole genome sequencing enable effective monitoring and mitigation of…
A site impacted by PCE and TCE was experiencing an accumulation of cis-DCE (DCE stall). CENSUS qPCR quantification demonstrated that Dehalococcoides concentrations were too low for effective rates of complete reductive dechlorination. Site managers asked: “Is bioaugmentation required or will biostimulation alone be sufficient to result in complete reductive dechlorination?” Monitoring with Bio-Traps® and CENSUS® analysis showed that stimulation…
A petroleum pipeline release in a remote area had gone undiscovered for a number of years and groundwater was impacted with BTEX. Groundwater monitoring results suggested that BTEX concentrations were decreasing although results were variable. The site managers asked for an additional line of evidence of BTEX biodegradation to support acceptance of an MNA management…
At a site impacted by trichloroethene (TCE), biostimulation and bioaugmentation were considered as remediation strategies. The site managers asked: “Is bioaugmentation required at this site for meaningful rates of reductive dechlorination?” The answer was no. An In Situ Microcosm (ISM) study showed conclusively that Dehalococcoides (DHC) was present at the site at low levels but could be significantly stimulated by…
At a petroleum pipeline release in a remote area Bio-Traps® and CENSUS® qPCR for BTEX catabolic functional genes proved stimulation of BTEX biodegradation in impacted groundwater and provided an additional line of evidence to support acceptance of an MNA management strategy at the site. Site managers asked: “Can molecular biological tools provide even more evidence…
An In Situ Microcosm study was conducted to evaluate MNA vs. enhanced anaerobic bioremediation via sulfate reduction at a petroleum impacted site. Site managers asked: “Will the injection of sulfate stimulate anaerobic BTEX biodegradation at this site?” The answer was yes. The ISM study showed conclusively that injection of sulfate at the site would increase the growth of…
