Action of Patulin on a Yeast [PDF]
Applied and Environmental Microbiology, 1983 The action of patulin on Saccharomyces cerevisiae was studied. At weak doses, the drug inhibited growth, but inhibition was transient. After 10 min, syntheses of rRNA, tRNA, and probably mRNA were blocked; this was shown by radioactive precursor incorporation assays and gel electrophoresis of RNAs. After recovery of

Patulin Biodegradation by Rhodosporidiobolus ruineniae and Meyerozyma guilliermondii Isolated From Fruits. [PDF]
MicrobiologyopenThis study investigated the effects of incubation time and temperature, and initial patulin concentration on patulin removal rates, and the mechanism involved in patulin degradation by Rhodosporidiobolus ruineniae and Meyerozyma guilliermondii. The patulin degradation rate by the yeast strains was dependent on the three key parameters.

Antagonistic activity of two yeasts against Penicillium expansum in stone fruits. [PDF]
J Sci Food AgricAbstract BACKGROUND Stone fruits are vulnerable to contamination by Penicillium expansum (PE), a patulin‐producing mould. The use of yeasts as biocontrol agents could be an effective strategy to combat this pathogen. This study evaluated the ability of Metschnikowia pulcherrima L672 (L672) and Pichia kudriavzevii L40 (L40) as biocontrol strategies on ...

Isolation and characterization of filamentous fungi capable of degrading the mycotoxin patulin
MicrobiologyOpen, 2023 Patulin is a toxic secondary metabolite synthesized by various fungal strains. This mycotoxin is generally toxic to microorganisms as well as mammals due to its reactivity with the important cellular antioxidant glutathione.

Toxins, 2023 Patulin is a mycotoxin with potential reproductive toxicity. We explored the impact of patulin on Leydig cell (LC) development in male rats. Male Sprague Dawley rats (21 days postpartum) were gavaged patulin at doses of 0.5, 1, and 2 mg/kg/day for 7 days.

Teratogenicity of patulin and patulin adducts formed with cysteine [PDF]
Applied and Environmental Microbiology, 1976 The mean lethal dose of patulin for the chicken embryo injected in the air cell before incubation was determined to be 68.7 mug and that for the 4-day-old embryo was 2.35 mug. Both patulin (1 to 2 mug/egg) and the reaction mixture between patulin and cysteine (15 to 150 mug of patulin equivalents) were teratogenic to the chicken embryo.

The Possible Mechanisms Involved in Degradation of Patulin by Pichia caribbica
Toxins, 2016 In this work, we examined the mechanisms involved in the degradation of patulin by Pichia caribbica. Our results indicate that cell-free filtrate of P. caribbica reduced patutlin content. The heat-killed cells could not degrade patulin. However, the live
