This contribution reports on the development of two versatile and efficient methods, namely green gamma radiolysis for Fe-Ag nanoparticles (NPs) synthesis, characterization, further their growth inhibition potential some spoilage microorganisms. Green Ag/Fe2O3 NPs were obtained at [3:1], annealing temperature 800 °C 2 h, irradiated Ag/Fe3O4 [7:1], a 50 kGy dose. The characterization techniques ...

Mandarin fruits are one of the most popular among Citrus genus. They consumed because their nutritional and health benefits, as well pleasant taste smell. This paper describes identification characterization Penicillium expansum, isolated from molded mandarin fruits. The obtained isolates were cultivated on five media [Czapek Yeast Autolysate agar (CYA), MEA (Malt extract agar), Creatine sucros...

The " discovery " of penicillin by Fleming in 1928 and its dramatic production, urged on by the necessities of war, heralded a new era of therapeutics. It has changed the pattern of disease the prognosis of infections, the expectation of life, indeed, it has changed the whole human ecology. Before the discovery of penicillin, there were many early descriptions of the characteristics and propert...

Penicillium expansum, a widespread filamentous fungus, is a major causative agent of fruit decay and may lead to the production of mycotoxin that causes harmful effects on human health. In this study, we compared the cellular and extracellular proteomes of P. expansum in the absence and presence of borate, which affects the virulence of the fungal pathogen. The differentially expressed proteins...

The fungistatic effects of controlled atmospheres composed of increased CO(2) and decreased O(2) was studied in a manner such that the condition of stored fruit was not a factor in the growth of the fungi. Varying concentrations of O(2) and CO(2) were used. The fungi used were Botrytis alli, Rhizopus nigricans, and Penicillium expansum. The results showed that controlled atmospheres, within the...

Aureobasidium pullulans strain Ach1-1 was recently isolated for its biocontrol effectiveness against Penicillium expansum, the causal agent of blue mold on harvested apples. In the present study, strain Ach1-1 was found to be very effective in controlling P. expansum on apple wounds. For in vitro tests, strain Ach1-1 and P. expansum were cocultured in the presence of apple juice (0 - 5%) using ...
