This Top Tips bulletin outlines best practices for diagnosing microbiologically influenced corrosion (MIC) using a multiple lines of evidence approach. It emphasizes the importance of molecular microbiological methods such as QuantArray®‑MIC and qPCR, strategic sampling design, and expert interpretation to accurately identify MIC risks and guide mitigation decisions.
This Top Tips bulletin explains why molecular microbiological methods (MMMs) are a critical component of modern corrosion management programs for identifying and managing microbiologically influenced corrosion (MIC). It highlights how DNA‑based tools such as qPCR, QuantArray®‑MIC, and next‑generation sequencing deliver accurate, cost‑effective insights that improve threat assessment, mitigation, and performance monitoring across industrial systems.
This technical overview explains the differences between CENSUS® qPCR and QuantArray® technologies and how each supports microbial characterization, remediation decision‑making, and performance monitoring. It provides practical guidance on when to use targeted single‑gene analysis versus multi‑gene array profiling to efficiently evaluate biodegradation, corrosion, and biogeochemical processes.
This white paper describes how stable isotope probing (SIP), QuantArray®‑Petro, and QuantArray®‑NSZD work together to evaluate biodegradation of petroleum hydrocarbons under real site conditions. By combining proof of degradation with pathway‑specific and microbial community data, these complementary tools support defensible decisions for monitored natural attenuation (MNA), bioremediation, and long‑term site management.
This white paper explains how combining molecular, mineralogical, and field‑based tools provides a more complete understanding of chlorinated compound degradation at contaminated sites. It shows how QuantArray®‑Chlor, abiotic testing, and in situ microcosms work together to improve remedy selection, support monitored natural attenuation, and increase confidence in site management decisions.
For over a decade, QuantArray®‑Petro, has provided engineers a high‑throughput qPCR platform that simultaneously quantifies functional genes involved in aerobic and anaerobic biodegradation of petroleum hydrocarbons, including BTEX, PAHs, MTBE, and alkanes. QuantArray®‑Petro provides defensible microbial lines of evidence to support monitored natural attenuation (MNA), evaluate enhanced bioremediation, and guide petroleum‑impacted site management decisions.
Used by practitioners around the world since 2012, this paper describes QuantArray®‑Chlor, a high‑throughput qPCR platform that simultaneously quantifies key microorganisms and functional genes involved in the biodegradation of chlorinated solvents. QuantArray®‑Chlor provides comprehensive, actionable data to support site assessment, remedy selection, and performance monitoring for chlorinated groundwater remediation.
This technical bulletin explains how aerobic cometabolism and abiotic degradation can be critical mechanisms supporting monitored natural attenuation (MNA) at chlorinated ethene sites, particularly in large or dilute plumes. It describes how molecular biological tools, mineralogical analyses, and degradation rate studies provide defensible evidence of contaminant destruction beyond traditional groundwater trend analysis.
This technical bulletin explains how molecular microbiological methods improve the detection, mitigation, and monitoring of microbiologically influenced corrosion (MIC) across industrial systems. It highlights the use of QuantArray®‑MIC, qPCR, and next‑generation sequencing within a multiple lines of evidence framework to identify MIC threats, guide mitigation strategies, and protect critical assets.
This technical bulletin shows how molecular biological tools can be integrated throughout the stages of remediation (site characterization, remedy selection, performance monitoring, and closure) to improve confidence in bioremediation decisions. It highlights the use of qPCR, QuantArray®, in situ microcosms, and stable isotope probing to reduce uncertainty, optimize remedies, and support transition to monitored natural…
