The study focuses on identifying key acid metabolites, known as 'signature' metabolites, which enhance our understanding of how petroleum hydrocarbons break down in various environments like aquifers and seawater.
Using advanced gas chromatography and mass spectrometry techniques, researchers successfully identified a variety of mono- and di-aromatic acid isomers from both commercial and biodegraded petroleum samples.
The findings suggest that these identified acids can help differentiate between various bacterial degradation processes, offering insights into the biodegradation pathways of aromatic petroleum compounds.
