Abstract: Three
fungal species isolated from sea water were screened for
crude oil biodegradation activity for a period of 25
days. Among the tested species, Aspergillus sp. showed
the higher capacity to degrade crude oil compared to
Fusarium sp. and Penicilium sp. The Total Hydrocarbon
concentration, Biological Oxygen demand and pH of the
samples were monitored at an interval of 5 days.
Aspergillus sp. had the potential of degrading 83.12% of
the hydrocarbons present in the polluted water whereas
Penicilium sp. and Fusarium sp. exhibited about 75.43%
and 69.89% hydrocarbon degradation ability respectively.
A uniform decline in BOD for the samples ranging from
41.64 % to 49.99 % at the end of 25 days was detected.
It was also found that the pH of the samples decreased
slightly as days progressed. This can be attributed to
the degradation of the available hydrocarbons to
numerous acids.
