Investigating of Difference between Dioxynivalenol Fungal Toxin Pollution Level in Raw Wheat Flour and Bread
Background Deoxynivalenol (DON) is one of the most common mycotoxins found in cereal grains. Objective The purpose of this survey was determination of difference between DON fungal toxin pollution level in raw wheat flour and bread. Methods: In this In the present analytical-cross-sectional study, to determine DON level, 44 subjects were random samplings of wheat, bread and flour (Lavash and ...
متن کاملStructure and function of a virally encoded fungal toxin from Ustilago maydis: a fungal and mammalian Ca2+ channel inhibitor.
BACKGROUND The P4 strain of the corn smut fungus, Ustilago maydis, secretes a fungal toxin, KP4, encoded by a fungal virus (UMV4) that persistently infects its cells. UMV4, unlike most other (non-fungal) viruses, does not spread to uninfected cells by release into the extracellular milieu during its normal life cycle and is thus dependent upon host survival for replication. In symbiosis with th...
متن کاملSpread and change in stress resistance of Shiga toxin-producing Escherichia coli O157 on fungal colonies
To elucidate the effect of fungal hyphae on the behaviour of Shiga toxin-producing Escherichia coli (STEC) O157, the spread and change in stress resistance of the bacterium were evaluated after coculture with 11 species of food-related fungi including fermentation starters. Spread distances of STEC O157 varied depending on the co-cultured fungal species, and the motile bacterial strain spread f...
متن کاملPlectasin, First Animal Toxin-Like Fungal Defensin Blocking Potassium Channels through Recognizing Channel Pore Region
The potassium channels were recently found to be inhibited by animal toxin-like human β-defensin 2 (hBD2), the first defensin blocker of potassium channels. Whether there are other defensin blockers from different organisms remains an open question. Here, we reported the potassium channel-blocking plectasin, the first defensin blocker from a fungus. Based on the similar cysteine-stabilized alph...
متن کاملProduction and Effect of Killer Toxin by Saccharomyces Cerevisiae on Sensitive Yeast and Fungal Pathogens
Killer toxins are the proteinaceous toxins produced by some group of yeast designatedKiller yeasts. These toxins have activity against microorganisms other than yeast and the activity is readily detectable only when a suitable sensitive strain is tested. The aim of this study was extract the Killer toxin from yeast cells, to purify by thin layer chromatography and to find out the action of kill...
