At the same time as strong ambition to improve sustainability and healthiness of food systems through a transition towards more plant-based diet, climate change is increasing risk plant diseases. Consequently, mycotoxigenic fungi have become safety issue major importance. A variety strategies suppress fungal growth in pre- postharvest stages production been established, potential various biolog...

Aspergillus flavus is a soil fungus that commonly invades peanut seeds and often produces carcinogenic aflatoxins. Under favorable conditions, the fungus-challenged peanut plant produces and accumulates resveratrol and its prenylated derivatives in response to such an invasion. These prenylated stilbenoids are considered peanut antifungal phytoalexins. However, the mechanism of peanut-fungus in...

An attempt was made to study the bioactive compounds from a terrestrial Streptomyces sp. ANU 6277 isolated from laterite soil. Four active fractions were recovered from the solvent extracts obtained from the culture broth of five day-old strain. Three bioactive compounds were purified and identified as 3-phenylpropionic acid, anthracene-9,10-quinone and 8-hydroxyquinoline. The components of the...

In this study, the effects of the storage duration of coffee cherries after harvest before putting out for sun drying on the kinetics of drying, fungi development and the variation of physicochemical content were evaluated. The results showed that the longer coffee cherries were stored after harvest before putting out for sun drying, the quicker they dried. Indeed, the drying durations were 19,...

Morphological changes of a toxigenic isolate of Aspergillus parasiticus cultured in the presence of aqueous leaf and seed extracts obtained from neem, Azadirachta indica A. Juss (syn. Melia azadirachta L.), a potent inhibitor of aflatoxin biosynthesis, was studied. Mycelial samples obtained from A. parasiticus cultures exposed to an effective concentration of the leaf and seed extracts (50% v/v...

The study was carried out to enumerate fungal contamination, and toxigenicity of Aspergillus flavus strains on cacao beans during drying storage. As many as 3500 g storage were purchased from smallholder farmers the plantation areas at Karo Regency, Northern Sumatera. percentage contaminated by fungi conducted using direct plating. Fungal populations soil determined dilution followed pour plate...

The occurrence of black aspergilli in onions has been reported as frequent, and this group fungi harbors potentially toxigenic species. In addition, Aspergillus niger the causative agent mold rot, an important postharvest disease that causes damage throughout world. Brazil stands out one world's largest onion producers. However, few studies have conducted to investigate mycobiota Brazilian onio...

Mycotoxins are toxic complexes generated by various genera of filamentous fungi and pose severe public health hazards due to their carcinogenic mutagenic properties. Toxigenic produce mycotoxins on foodstuffs when favorable conditions for production exist. The most important mycotoxin-producing fungal Aspergillus, Fusarium Penicillium. major mycotoxin concern, including aflatoxins, trichothecen...

Aims: To determine the anti-cytotoxic effects of Lactobacillus rhamnosus GG (LGG) against extracellular and intracellular Clostridium difficile toxins. Study Design: Co-culture system. Place and Duration of Study: Division of Infectious Diseases, Department of Medicine, School of Medicine and Public Health and Department of Pathobiological Sciences, School of Veterinary Medicine, Madison, Wisco...
