EOS Remediation and Microbial Insights invite you to a webinar: Biomarker-based Tools to Validate 1,4-Dioxane Biodegradation
DATE: July 22, 2015; TIME: 12:00PM – 1:00PM EDT; SPEAKER: Shaily Mahendra
1,4-Dioxane is an emerging contaminant of concern, commonly associated with chlorinated solvent plumes. Due to its high solubility in water, resistance to biodegradation under natural conditions, and ineffective removal by technologies, 1,4-Dioxane tends to persist in wastewater and groundwater. 1,4-Dioxane biodegradation, catalyzed by monooxygenase enzymes, has been established in laboratory studies with several aerobic bacteria. Pseudonocardia dioxanivorans CB1190 is a microbe capable of using 1,4-Dioxane as a sole carbon and energy source. We recently identified a set of monooxygenase and dehydrogenase genes relevant for 1,4-Dioxane biodegradation. Primer sets for amplifying 1,4-Dioxane specific biomarkers were validated in activated sludge samples as well as in a contaminated aquifer using Advanced BioTraps baited with CB1190.
In this webinar, Dr. Shaily Mahendra will present results of the first authenticated field application that quantifies the abundance as well as expression of 1,4-Ddegrading monooxygenase genes, and relates the biomarker responses to 1,4-Dioxane biodegradation in complex environmental samples. You will learn how her work demonstrates the importance of biomarkers as a supporting line of evidence for in situ biodegradation of 1,4-Dioxane.
