Unveiling the Substrate‐Dependent Dynamics of Mycotoxin Production in Fusarium verticillioides Using an OSMAC‐Metabolomics Approach

Chemistry &Biodiversity, Volume 22, Issue 1, January 2025.
Abstract Fusarium verticillioides is a prevalent plant pathogenic fungus known to produce harmful mycotoxins, including fumonisins and emerging toxins. This study aimed to investigate the influence of substrate on the temporal patterns of mycotoxin biosynthesis by F.

Mycotoxins and related Fusarium species in preharvest maize ear rot in Poland

Plant, Soil and Environment, 2016
This work presents a survey on mycotoxins (seasons 2013 and 2014) and Fusarium species (seasons from 1985 to 2014) in maize ear rot in Poland. Twelve mycotoxins were identified in maize kernel samples exhibiting symptoms of Fusarium ear rot or rotten ...

Lactic Acid Bacteria and Bacteriocins in Feed Preservation: Mechanisms and Antifungal Properties

Grass and Forage Science, Volume 80, Issue 1, January-March 2025.
ABSTRACT Ensilage consists of the fermentation of sugars to lactic acid independent of the forage by epiphytic microorganisms, lactic acid bacteria (LAB), which vary in number and composition during fermentation. Silage is a means of preserving forage for extended periods of time when fresh forage is limited or seasonally unavailable, and its ...

Cooccurrence of Mycotoxins in Maize and Poultry Feeds from Brazil by Liquid Chromatography/Tandem Mass Spectrometry

The Scientific World Journal, 2013
The objective of this study was to quantitatively evaluate mycotoxins in samples of maize and poultry feed produced in Brazil. A multimycotoxin method based on HPLC-MS/MS was applied to investigate the occurrence of toxical fungal metabolites in 119 ...

Comparing the activity and interactions of the antifungal protein PeAfpA with conventional fungicides and food preservatives against mycotoxigenic fungi

International Journal of Food Science &Technology, Volume 59, Issue 12, Page 9326-9335, December 2024.
PeAfpA is an antifungal protein produced by Penicillium expansum. In this study, the activity of this protein was compared with fungicides (imazalil and thiabendazole) and preservatives (calcium propionate, sodium, sodium benzoate, potassium sorbate and natamycin). In addition, the effect of PeAfpA in combination with imazalil, thiabendazole, natamycin

Influence of regional and yearly weather patterns on multi‐mycotoxin occurrence in Austrian wheat: a liquid chromatographic–tandem mass spectrometric and multivariate statistics approach

Journal of the Science of Food and Agriculture, Volume 104, Issue 13, Page 7788-7796, October 2024.
Abstract BACKGROUND Mycotoxin surveys play an essential role in our food safety system. The obtained occurrence data form the basis for the assessment of the exposure of humans and animals to these toxic fungal secondary metabolites. Liquid chromatography coupled with tandem mass spectrometry (LC‐MS/MS) has become the gold standard for mycotoxin ...

Stability of Mycotoxins in Individual Stock and Multi-Analyte Standard Solutions

Toxins, 2020
Standard solutions of mycotoxins prepared in RP HPLC solvents from neat standards are usually used for analytical method development. Multi-mycotoxin HPLC-MS/MS methods necessitate stability estimation for the wide spectrum of fungal metabolites.

Comparative Genomics of Conifer‐Associated Fusarium spp.

Forest Pathology, Volume 54, Issue 5, October 2024.
ABSTRACT Recent studies have shown numerous Fusarium spp. are associated with symptomatic conifer seedlings in both bareroot and container nursery systems. Some of these species have been found pathogenic to conifer seedlings (e.g., F. avenaceum, F. commune, F. oxysporum, F. solani, and F.
