Additional information
There are four studies available for octane. The study that shows best the rapid biodegradability of this substance was conducted by Haines and Alexander (1974) using a procedure from the standard methods for the examination of water and waste water. Degradability was assessed by measurement of the biological oxygen demand. In this study octane is reported to biodegrade to 70% after 10 days with an unacclimated sewage sludge inoculum. The other studies using different methods and durations have also shown octane to biodegrade rapidly. Solano-Serena et al. (1999) investigated the degradation of gasoline by a microflora from urban waste water activated sludge. Unacclimated activated sewage sludge was used as the inoculum. Biodegradation resulted in 60% before day 10. In a study by Malaney and McKinney (1966) octane exhibited 28.4% biodegradation after 3 days with an non-adapted sludge inoculum.Nagata and Kondo (1977)reported that n-nonane biodegraded in two tests to 67% and 100% after 15 days with an unacclimated sediment and seawater inoculum.
