Fungicides are the most common agents used in postharvest treatment of fruit and are the most effective against blue mould, primarily caused by Penicillium expansum. Alternatively, blue mould can be treated with antagonistic microorganisms naturally occurring on fruit, such as the bacterium Gluconobacter oxydans. The aim of this study was to establish the antifungal potential of the G. oxydans 1J strain isolated from apple surface against Penicillium expansum in culture and apple juice and to compare it with the efficiency of a reference strain G. oxydans ATCC 621H. The highest antifungal activity of G. oxydans 1J was observed between days 3 and 9 with no colony growth, while on day 12, P. expansum colony diameter was reduced to 42.3 % of the control diameter. Although G. oxydans 1J did not fully inhibit mould growth, it showed a high level of efficiency and completely prevented patulin accumulation in apple juice.

Abstract A description is provided for Penicillium expansum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Found commonly in soil and in a wide variety of organic material including grains and cereal products, and though generally isolated from mouldy fruit, particularly apples, it also occurs on other pomaceous fruit, cherries, grapes, olives, pineapple and sometimes on citrus and avocado (Raper & Thom 1949, 518-522, & Herb. IMI). DISEASE: Blue mould (soft rot) of apple is characterized by the formation of watery, light or yellowish brown areas on the fruit, which may originate from either the stem or calyx ends. A soft brown rot develops which rapidly destroys the whole fruit. Later, under humid conditions, tufts of massed conidiophores with blue-green conidia appear on the surface of the fruit which gives off a characteristic musty odour. GEOGRAPHICAL DISTRIBUTION: World-wide. TRANSMISSION: By air and soil-borne spores, especially in orchards. The pathogen commonly enters through wounds and injuries but may also penetrate lenticels (11: 658).
