Synthesis of beauvericin by a multifunctional enzyme.

The Journal of Antibiotics, 1988
Beauvericin synthetase, a multifunctional enzyme catalyzing depsipeptide formation in Beauveria bassiana was purified to near homogeneity. The enzyme consists of a single polypeptide chain with a molecular mass of about 250 kdaltons. The mechanism of beauvericin formation is very similar to that of the cyclohexadepsipeptide enniatin.

The role of pumpkin pulp extract carotenoids against mycotoxin damage in the blood brain barrier in vitro

Arhiv za Higijenu Rada i Toksikologiju, 2021
Some mycotoxins such as beauvericin (BEA), ochratoxin A (OTA), and zearalenone (ZEA) can cross the blood brain barrier, which is why we tested the anti-inflammatory action of a pumpkin carotenoid extract (from the pulp) against these mycotoxins and their

Occurrence of mycotoxins in milk and dairy products in Brazil: A review of recent data, regulatory aspects, preventive and decontamination strategies

International Journal of Dairy Technology, Volume 79, Issue 2, April–June 2026.
Mycotoxin data in Brazilian milk and dairy products over 20 years indicate aflatoxin M1 as the most frequent, although ochratoxin A, fumonisins and deoxynivalenol were also found in some studies. These data underscore the importance of control measures to reduce dietary mycotoxins in Brazilian dairy feed and avoid their residues in milk.

Human skin permeation of emerging mycotoxins (beauvericin and enniatins) [PDF]

Journal of Exposure Science & Environmental Epidemiology, 2015
Currently, dermal exposure data of cyclic depsipeptide mycotoxins are completely absent. There is a lack of understanding about the local skin and systemic kinetics and effects, despite their widespread skin contact and intrinsic hazard. Therefore, we provide a quantitative characterisation of their dermal kinetics.

First Total Syntheses of Beauvericin A and allo-Beauvericin A

The first total syntheses of beauvericin A and allo-beauvericin A were achieved. N-Methyl-l-phenylalanine, (2R)-hydroxylvaleric acid, and (2R,3S)- or (2R,3R)-2-hydroxy-2-methylpentanoic acid were linked and cyclized to form the target natural products ...

Mycotoxins in plant‐based drinks (soy, almond and oat): the BfR updates its assessment of their health risks based on newly collected data

Food Risk Assess Europe, Volume 4, Issue 2, April 2026.
Abstract Mycotoxins (mould toxins) are secondary metabolites of moulds. They are natural toxins whose occurrence in food and feed is undesirable but cannot be completely avoided. Mycotoxins may occur as contaminants in plant products and raw materials such as grains, nuts and almonds if they are infested with mould during cultivation, storage or ...

Effects of beauvericin on T lymphocyte proliferation and activation.

, 2013
(A) Beauvericin suppressed T cells proliferation. CD3+ T cells pretreated with CFSE (5 µM, 10 min) were incubated for 72 h at 37°C under 5% CO2 in the presence of Con A, with or without 1.25–10 µM beauvericin.

Assessment of Pathogenicity and Aggressiveness of Fusarium poae on Wheat and Barley

Plant Pathology, Volume 75, Issue 2, March/April 2026.
Four Fusarium poae isolates were evaluated for pathogenicity and aggressiveness on soft red winter wheat, durum wheat and barley under greenhouse conditions. Although less aggressive than a reference Fusarium graminearum isolate, F. poae caused measurable disease, with the greatest impact in durum wheat, highlighting host‐type differences in ...

Systemic Activation of the Antioxidant System by Root Priming With Non‐Pathogenic Fusarium oxysporum in Flax Infected With Pathogenic Fusarium oxysporum

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Fusarium oxysporum Fo47 primes flax by locally suppressing pathogens in roots and systemically activating antioxidant defences in shoots, offering a sustainable plant protection strategy. ABSTRACT Plants rely on specialised adaptive mechanisms to enhance resistance against environmental stress.
