The fungi associated with the spoilage of pineapple fruits in Abidjan market were studied. Spoilt and healthy pineapple fruits were used in the study with potatoes dextrose agar as the culture medium while the pour plate technique was employed in the fungal isolation. Restriction digestion analysis of the ITS products was tested as a simple method to identify isolates of filamentous fungi on pineapple fruits. Endonucleases SduI, HinfI, HhaI, NlaIII, HaeIII, RsaI were used. The studied 10 species generated different composite profiles. Different fungal strains responsible for the spoilage were isolated from various markets in Abidjan and identified by this method. Aspergillus was the genus the most frequently isolated, while the genus Penicillium was absent. Aspergillus aculeatus was the most isolated species of Aspergillus. The Candida sp., Rhizopus oryzae and Geotrichum candidum were also isolated. To the best of our knowledge, is the first report of the presence of Neurospora tetrasperma on pineapple. This technique is a rapid and reliable method appropriate for routine identification of fungi. This can be used to screen large numbers of isolates from various environments in a short time. This is the first exhaustive study of fungal diversity at species level in pineapple fruits.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
