| Abstract | ||
| The present study was conducted to isolate the fungus (different isolates) that cause rotting of the yellow apple and identify the fungus depending on many characters including morphological, physiological, and the ability of the isolates to produce some secondary metabolites (Extrolites) like indole alkaloids (Ehrlich test) and the mycotoxin patulin. Results showed isolation of 35 isolates of Penicillium expansum only. Capability of 33 isolates of this fungus to produce patulin was tested. All isolates were capable of producing patulin. The amount of patulin produced varied with isolates, the average production by all isolates was within the concentration (12254.84- 2.074) ppm. Patulin contamination is considered of great concern especially in apples and apple products due to its harmful effect on human life. | ||
