Abstract:
Beauvericin is a depsipeptide mycotoxin. The production of several beauvericin analogues has previously been shown among various genera among Hypocreales fungi. This includes so-called beauvenniatins, in which one or more N-methyl-phenylalanine residues is exchanged with other amino acids. In addition, a range of “unnatural” beauvericins has been prepared by a precursor addition to growth medium. Our aim was to get insight into the natural production of beauvericin analogues among different Hypocreales fungi, such as Fusarium and Isaria spp. In addition to beauvericin, we tentatively identifie

Abstract:
Hulless oats and hulless barley are highly valued for their excellent nutritional attributes and are increasingly being promoted in human nutrition. However, special attention should be paid to the risk of their contamination by Fusarium mycotoxins, as the rate of mycotoxin reduction during processing could be much lower than that for hulled cereals. In the present study, mycotoxin contamination of two cultivars, each of hulless oats and barley suitable for food purposes were studied in a 3-year field trial established in two contrasting environments. The contents of the mycotoxins regulated b

This review provides comprehensive information on beauvercin, a cyclic hexadepsipeptide, produced by selected fungi like Beauveria, Paecilomyces, Polyporus, Isaria and Fusarium. The biosynthetic pathway of beauvericin production is elaborated. Numerous bioactivities like anticancer, antiviral, cytotoxic, antiplatelet aggregation, antimicrobial, antiprotozoal, insecticidal properties are reviewed. The potential of beauvericin to diminish the growth of gram-positive or gram-negative pathogenic bacteria and inhibition of melanin production are well documented.

ABSTRACT Beauvericin is a cyclohexadepsipeptide mycotoxin which has insecticidal properties and which can induce apoptosis in mammalian cells. Beauvericin is produced by some entomo- and phytopathogenicFusarium species (Fusarium proliferatum,F. semitectum, and F. subglutinans) and occurs naturally on corn and corn-based foods and feeds infected byFusarium spp. We tested 94 Fusarium isolates belonging to 25 taxa, 21 in 6 of the 12 sections of theFusarium genus and 4 that have been described recently, for the ability to produce beauvericin.

Abstract:
Beauvericin (BEA) is a cyclodepsipeptide mycotoxin, showing insecticidal, antibiotic and antimicrobial activities, as well as inducing apoptosis of cancer cell lines. BEA can be produced by multiple fungal species, including saprotrophs, plant, insect and human pathogens, particularly belonging to Fusarium, Beauveria and Isaria genera. The ability of Trichoderma species to produce BEA was until now uncertain. Biosynthesis of BEA is governed by a non-ribosomal peptide synthase (NRPS), known as beauvericin synthase (BEAS), which appears to present considerable divergence among different fungal s

Although histological data suggest that cholangiocytes die by apoptosis in human liver diseases, no information exists on the mechanisms of cholangiocyte apoptosis. Thus our aims were to establish an in vitro model of cholangiocyte apoptosis and to test the hypothesis that changes in intracellular ions would cause apoptosis in cholangiocytes by a protease-sensitive pathway. A large number of proapoptotic agents were ineffective in inducing apoptosis in rat or human cholangiocytes in culture; in contrast, beauvericin, a K+ ionophore, caused apoptosis in both cell lines, despite their expression
