This technical bulletin examines the ability of cold‑adapted (psychrophilic) microorganisms to biodegrade petroleum hydrocarbons in cold and permafrost environments. It highlights how molecular tools such as QuantArray®‑Petro can identify and quantify key biodegradation pathways to support bioremediation decisions at low‑temperature sites.
This technical bulletin explains how to design, implement, and evaluate electron donor addition to enhance anaerobic bioremediation at chlorinated solvent sites. It highlights how molecular biological tools such as CENSUS® qPCR, QuantArray®‑Chlor, and in situ microcosms are used to determine bioaugmentation needs, optimize biostimulation, and verify remedy performance over time.
This technical bulletin explains how selecting the appropriate sampling matrix—groundwater, sediments, or Bio‑Trap® samplers—affects the interpretation of Dehalococcoides (DHC) and functional gene data for evaluating in situ reductive dechlorination. It provides practical guidance on using CENSUS® qPCR and QuantArray®‑Chlor results to support site assessment, remedy selection, and performance monitoring at chlorinated solvent sites.
