KEYWORDS: Crude oil, poilution, fungal growth.


The vegetative growth response of some fugi to different concentrations of crude oil was in/estigated. The result showed avariable degree of sensitivity to crude oil. The radial growth of Rhizopus sp. was not affected by the oil irrespective of theconcentration. The two species of Aspergillus A. niger and A. flavus used in the study appreciably tolerated the oil though the srowth of A. flavus was retarded as the concentration of oil increased. Botrytis cinerea, Curvularia lunata and Colletotrichum sp. could not grow beyond the concentration of 1mll 10mls of oil in Potato Dextrose Agar (PDA). The three fungi could serve as sensitivity index for monitoring oil polution in an environment
