| Abstract | ||
| The present study involved the isolation and diagnosis of molds and yeasts which affecting the local and imported citrus fruits available in the local markets of the Mosul. These fruits include (grapefruit, oranges, lemons, sweet limes, oranges Japanese, sour, bitter orange and tangerine) .45 isolates were obtained from filamentous fungi and 26 isolates also were obtained from yeasts.The fungi were identified morphogically and microscopically based on Pitt and Hocking taxonomic index(2009) . The molds samples were distributed to the following species Penicillium, Aspergillus, Cladosporium, Mucor, Alternaria, Trichoderma, Fusarium, Rhizopus. The two genera Aspergillus and Penicillium were identified to the species level, because of their frequent ocurrence in the isolates, as well as the yeasts were diagnosed morphogically and microscopically, their growth have been studied on the differential medium.The system Vitek 2 Compact also has been used .Distinction was made between Basidiomycetes and Ascomycetes yeasts. yeasts samples were distributed to 5 genera.They are Crptococcus spp, Candida spp, Saccharomyces spp,, Rhodotorula mucillaginosa, and Geotrichum candidum.The present study included the use of Candida guilliermondii (which has been isolated during the present study), yeast as biological control for the isolated yeast of the present study. The yeast showed high efficiently in inhibiting molds growth specially P. italicum and A. niger , the yeast inhibited their growth completely and it was 100% . | ||
