A comparison of the biodegradation of aromatic hydrocarbons in three different systems
- Curtin Univ. of Technology, Perth (Australia)
In three case studies, the circumstances in which petroleum hydrocarbon biodegradation took place were markedly different. (1) Two reservoir-biodegraded oils from the Barrow Sub-basin. (2) Petroleum hydrocarbons from a condensate which had seeped into a mangrove creek bed. (3) Hydrocarbons in sediments exposed to drilling discharges from an off-shore petroleum platform. For each case, the progress of biodegradation of the aromatic hydrocarbons was studied in detail using GC-MS and GC-FTIR, so that the susceptibility to biodegradation of individual methylated naphthalenes and alkylphenanthrenes could be established. Striking similarities were observed in the progress of biodegradation in the three different environments, especially with the alkylnaphthalenes. One particularly prominent feature of all three systems was that 1,6 dimethyl substituted naphthalenes are more susceptible than other isomers. These similarities raise interesting questions about the mechanisms of biodegradation in these three systems.
