Time-resolved quantification of alkylsuccinic acids and aromatic hydrocarbon metabolites detected in the (A) light and (B) heavy oil-amended cultures. Characteristic ion fragments m/z 262 and (M – 15)+ were selected to probe and integrate TMS-derivatized alkylsuccinates and organic components, respectively. Identification and quantification of metabolites was performed using calibration curves prepared from authentic standards.
