Abstract

In the present study, soil sample was collected from diesel spill soil at Chennai harbour. Bacterial colony isolated from the soil was screened for their ability to grow in the medium containing diesel. The selected bacterial isolated was subjected to taxonomic identification and tentatively as Bacillus spp. Bacillus spp tested for their efficiency to degrade diesel with four different concentrations. The degradation of diesel was recorded by the measurement of carbon-di-oxide and biomass. Degradation was measured in 42 hours for 16 days. Degradation was maximum in 10%.
