Abstract

Fungi associated with five different water bodies (Abraka, Oghara, Sapele, Mosogar and Ubeji Rivers) in Delta State were investigated. A total of twenty (20) samples were collected with four replicates for each water body. The water bodies except Abraka are within the oil producing area of Delta State. One ml of water sample from each of the water bodies was cultured using Sabouraud Dextrose Agar (SDA). Five fungi comprising three genera and five species were isolated and characterised: Penicillium species (Abraka), Fusarium verticillioides (Mosogar), Aspergillus flavus (Sapele), A. niger (Oghara) and Penicillium rolfsii (Ubeji). From the physicochemical characteristics conducted, the highest values for turbidity, conductivity and total polyhydrocarbon were found in water samples from Sapele (5.80 ± 0.55) NTU, Oghara (96.60 ± 1.47) µS/cm and Ubeji (416.67 ± 5.35) respectively. These values can be attributed to high level of pollution or low level of fungal biodegradation. Since these fungi have shown the capacity to survive and metabolize ions as decomposers in these water bodies, they have potentials for use in bioremediation in the clean-up of contaminated environment.
