Additional information on environmental fate and behaviour
Administrative data
- Endpoint:
- additional information on environmental fate and behaviour
- Type of information:
- migrated information: read-across based on grouping of substances (category approach)
- Adequacy of study:
- key study
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- The Wentzel et al (2007) article is a review article and therefore cannot be given a reliability rating. The Wongsa et al. (2004) article is well documented and may be eligible for a reliability of 2, but for the purposes of this section has been given a reliability of 4.

Results and discussion
Applicant's summary and conclusion
- Conclusions:
- Degradation of alkanes is a widespread phenomenon in nature, and numerous microorganisms capable of using these substrates as a carbon and energy source have been isolated and characterized. Such microorganisms are capable of degrading alkanes and converting them to easily metabolizable substrates. Wentzel et al. (2007) is a review paper that summarizes recent advances in the understanding of bacterial metabolism of long-chain n-alkanes. Wongsa et al. (2004) is one example of several technical papers that show degradation of long chain n-alkanes in complex mixtures like gasoline, kerosene, diesel oil and lubricating oil. In the most described cases, the n-alkane is oxidized to the corresponding primary alcohol by substrate-specific terminal monooxygenases/hydroxylases. Subterminal oxidation has also been described both for long-chain n-alkane substrates up to C16 and for n-alkanes of shorter chain lengths. After the initial oxidation of the n-alkane, the corresponding alcohol is subsequently oxidized further by alcohol dehydrogenase and aldehyde dehydrogenase to the corresponding aldehyde and carboxylic acids, respectively. The carboxylic acid then serves as a substrate for acyl-CoA synthetase, and the resulting acyl-COA enter the β-oxidation pathway. Rates of these reactions vary depending on the composition of the mixtures and other factors. Wongsa et al. (2004) found that about 90-95% of the total diesel oil and kerosene added to mineral salts media as a sole carbon source could be degraded by one strain of bacteria within 2 and 3 weeks, respectively. The same amount of lubricating oil was 60% degraded within 2 weeks. Another strain of bacteria was even more efficient in degrading aromatic compounds in gasoline. This second strain could also degrade kerosene, diesel and lubricating oil with a capacity of 50-60%.
