Decaying bamboo leaf samples were collected from two streams within the University of Ibadan, Ibadan, Nigeria. Fungal isolates were obtained from the leaves through direct plating, leaf washing and baiting techniques. A total of forty fungal isolates were obtained, they were identified as Aspergillus, Fusarium, Mucor, Rhizopus, Trichoderma and some unidentified genera. The fungal isolates were assayed for the presence of cellulase and lignase activity. All the 13 isolates used (which were representatives of all fungi obtained) showed the presence of cellulase, lignin peroxidase and manganese peroxidase. The study showed that aquatic fungi produce a wide range of enzymes necessary for the breakdown of plant tissues which are the major source of carbon in streams.
