Abstract

Studies on fungi isolates were carried out over a period of 4 weeks with different rotting fruits that were collected from sellers in Yankaba market, Kano. The fruits are sweet orange, apple, pineapple, watermelon, banana, pawpaw, coconut and wild bush mango were collected in clean sterile polythene bags separately. Each of the samples was cultured and isolated at room temperature (37⁰C). Materials used in culturing included Petri-dishes with potato dextrose agar as the media. Methylene blue was used in mounting and slide staining. It took a period of 7 days to incubate and isolate the fungi namely Aspergillus spp., Sclerotium spp., Trichoderma spp., Gloeosporium spp., Rhizopus spp. and Rhizoctonia spp. were responsible for post-harvest deterioration of fresh fruits and vegetables. Rhizopus spp. had the highest frequency of occurrence.
