Killer Saccharomyces cerevisiae and Wickerhamomyces anomalus yeast strains were tested as biocontrol agents against Penicillium digitatum, one the most important causes of postharvest decay in orange fruits. W. anomalus, grown on acidified medium, demonstrated micocinogenic activity against P. digitatum, as indicated by large inhibition halos and hyphal damage resulting from β-glucanase activity. Oranges that had been deliberately inoculated with pathogens were protected from decay by W. anomalus. Inoculation of oranges with W. anomalus strains BS 91 and BS 92 reduced disease severity to 1 and 4%, respectively, for up to 10 days in storage.
