Evaluation of antagonistic activity of epiphytic yeasts against rot pathogens of mandarin orange and grapefruit.

Biocontrol activity of a wide range of epiphytic yeasts against postharvest decay of citrus was evaluated on grapefruit. Antagonistic yeasts were isolated from the surface of mandarin orange in Turkey and grapefruit in Israel. Their antagonistic activity against green and blue mould, caused by Penicillium digitatum and P. italicum, respectively, was evaluated directly on the fruit. Among the mandarin orange isolates, three were effective in inhibiting green mould. Among the grapefruit isolates, several yeasts showed high efficacy against green and blue mould and sour rot caused by Geotrichum candidum. At the wound site, the population of yeasts increased gradually and maintained a high concentration during one week of storage at 20 deg C. RAPD-PCR and ap-PCR analysis indicated the presence of three groups of yeasts only.
