FIG 2.

Potential of bacterial strains to degrade or transform petroleum hydrocarbons. Values are relative to those from the uninoculated control and are corrected for extraction efficiency and mass of oil added. TPHs were used by summing areas under each peak as determined by GC-FID. (A) Oil degradation potential for Alcanivorax sp. P2S70; (B) oil degradation potential for Acinetobacter sp. COS-3. An outlier from Acinetobacter was removed; see Fig. S3 for a version of this figure that includes the outlier. Asterisks indicate samples that are significantly different from the control samples. Data shown were collected after 7 days of incubation.
