A Transposon Screen for Detecting Naphthenic Acids

This year, our team wanted to identify a novel responsive element capable of detecting and quantifying naphthenic acids (NAs) in solution. While numerous studies have begun to identify species of bacteria capable of surviving and sensing NAs, the degradation pathways have not yet been fully characterized. Therefore, we needed to design and implement novel approaches to efficiently isolate the genetic elements that detect and potentially lead to the breakdown of naphthenic acids.

Pseudomonads are species of aerobic bacteria that have been isolated from oil sands tailings ponds and shown to biodegrade model and tailings-associated NAs (Ramos-Padrón et al. 2010; Herman et al., 1994; Del Rio et al., 2006; Gieg & Whitby, unpublished, 2012).
