Outer Membrane Proteins of Filamentous Fungi Isolated from Wheat (Triticum spp.) In Lagos State, Nigeria

This study determined the outer membrane proteins of filamentous fungi isolated from wheat in Lagos State, Nigeria using SDS-PAGE. The results obtained revealed 22 protein bands with molecular weights ranging from 8-16KDA. Aspergillus fumigatus and Aspergillus niger contains 5 and 3 protein bands ranging from 10 to 15 KDA and 10 to 14 KDA respectively. Aspergillus flavus, Alternaria, Rhizopus, Penicillium and Fusarium spp contains 2 protein bands ranging from 11 to 14 KDA. Trichoderma however revealed 4 protein bands that ranges from 8-16KDA. Among these bands, protein band with molecular weight of 13KDA were found in Asp. fumigatus, Asp.niger, Fusarium species, Rhizopus and Penicillium spp. It can thus be inferred that the different filamentous fungi studied have different antigenic determinants as revealed by difference in their electrophoretic patterns.
