In this study, contamination by microscopic fungi (focused on Penicillium and Aspergillus species) of 75 fruit samples (strawberries, blackberries, blueberries, raspberries, grapes) 29 tomato samples, which were obtained from Slovak stores was investigated. Totally 93.3% contaminated with micromycetes (70.6% Botrytis spp., 52.0% Cladosporium 42.7% 13.3% Rhizopus 8.0% Alternaria 6.7% Mucor 5.3% ...

Eleven samples of grapes from the Central Slovak wine-growing region were examined at time harvest in 2021 using plating method and with surface disinfection. Plates incubated aerobically 25±1 °C dark for one week. Identification fungi was based on morphological microscopic characteristics. Of 574 strains detected identified exogenous mycobiota, most common genus Alternaria (90.9%), followed by...

The yeast-like fungus Aureobasidium pullulans PL5 is a microbial antagonist against postharvest pathogens of fruits. The strain is able to produce hydrolases, including glucanases, chitinases and proteases. The alkaline serine protease gene ALP5 from A. pullulans was cloned, inserted into the vector pPIC9 to construct pPIC9/ALP5, and then expressed in Pichia pastoris strain KM71. ALP5 had a mol...

How the host cells of plants and animals protect themselves against fungal invasion is a biologically interesting and economically important problem. Here we investigate the mechanistic process that leads to death of Penicillium expansum, a widespread phytopathogenic fungus, by identifying the cellular compounds affected by hydrogen peroxide (H(2)O(2)) that is frequently produced as a response ...

Apple is one of the most important temperate fruit to Brazil economy, and the use of synthetic chemicals has been the main method for reducing postharvest diseases, such as the blue mold, caused by Penicillium expansum. This work intends to evaluate the practical utilization of chitosan for blue mold control. For this purpose, fruits were treated in a preventive and curative way, immersing the ...

Certain strains of Pantoea are used as biocontrol agents for the suppression of plant diseases. However, their commercial registration is hampered in some countries because of biosafety concerns. This study compares clinical and plant-beneficial strains of P. agglomerans and related species using a phenotypic analysis approach in which plant-beneficial effects, adverse effects in nematode model...

AIMS To investigate the effect of antagonistic yeast Pichia membranaefaciens on alleviating oxidative stress caused by Penicillium expansum in sweet cherry fruit. METHODS AND RESULTS At two maturity stages of sweet cherry fruit, P. membranaefaciens restrained blue mold rot caused by Pe. expansum. There was not any decay in yeast-treated fruit even at 5 days after inoculation. Carbonylated pro...
