Incidence and Distribution of Filamentous Fungi during Storage of Coffee Beans in Eastern Region, Kingdom of Saudi Arabia (original) (raw)

This Study Aimed to determine and identify fungi associated with four varieties of coffee beans (Coffea arabica L.) were collected from different grocery stores and retail markets in an eastern region of the Kingdom of Saudi Arabia: harary, lukkimy, habbashy and barry. However the highest percentage of fungal infection was associated with harary (36.26%of infection) followed by lukkimy (29.13%), habbashy (20.50%) and barry (14.12%). Several fungi associated with four varieties were isolated at the following frequencies: Aspergillus niger (74.71%), Aspergillus alliaceus (7.33%), Aspergillus melleus (4.32%), Aspergillus tubingensis (4.27%), Fusarium solani (3.56%), Aspergillus flavus (2.01%), Penicillium oxalicum (1.61%), Alternaria alternata (1.2%), Emericella nidulans (0.85%) and Paecilomyces variotii (0.15%). The potency of the first five most frequent fungi to infect all studied seeds was ranked, in decreasing order, as: A. niger, A. alliaceus and A.melleus (100%) however Fusarium...
