Airborne fungi are one of the major components aeromycobiota known to produce several fungal diseases in fruits. Their presence indoor environment warehouses may limit storage period apples. Qualitative and quantitative analyses airborne spores were conducted using gravity settling techniques detect airspora present atmosphere two apple Tunisia. In this study, 375 isolates obtained purified. Ph...

Biocontrol activity of Metschnikowia pulcherrima alone and in combination with silicon against Penicillium expansum and its machanisms of antagonisms was evaluated. Percentage of inhibition mycelial growth of pathogen in dual culture, volatile test and non-volatile test were evaluated. To evaluate the direct effect of silicon on mycelial growth of P. expansum in vitro, it was added at different...

The biocontrol activity of Aureobasidium pullulans on decay of apple fruit caused by Botrytis cinerea and Penicillium expansum, and its ability to induce biochemical defense responses in apple tissue, were investigated. In apple wounds, A. pullulans multiplied rapidly and controlled decay caused by either B. cinerea or P. expansum. At the end of the storage period, A. pullulans reduced the inci...

Biofilms can be considered the main source of microorganisms in drinking water distribution systems (DWDS). The ecology a biofilm is dependent on variety factors, including presence microbial metabolites excreted by its inhabitants. This study reports effect Gram-negative bacteria Methylobacterium oryzae idh gene expression levels and patulin production Penicillium expansum mature biofilms. For...

The application of the biocontrol agent Pantoea agglomerans EPS125 to unwounded fruits was practically ineffective for control of postharvest blue mould caused by Penicillium expansum when the treatment and subsequent wounding and pathogen inoculation were separated by periods of unfavourable conditions. This was due to a rapid decrease in viability of the alocthonous introduced biocontrol agen...

Eight substances that are main components of the essential oils from three Mediterranean aromatic plants (Verbena officinalis, Thymus vulgaris and Origanum vulgare), previously found active against some phytopathogenic Fungi and Stramenopila, have been tested in vitro against five etiological agents of post-harvest fruit decay, Botrytis cinerea, Penicillium italicum, P. expansum, Phytophthora c...

Alternatives to hypochlorous acid and fungicides are needed for treatment of fruit and fruit-handling facilities. Chlorine dioxide was evaluated and found effective against common postharvest decay fungi and against filamentous fungi occurring on fruit packinghouse surfaces. In vitro tests with conidial or sporangiospore suspensions of Botrytis cinerea, Penicillium expansum, Mucor piriformis, a...
