Emerging fusarium-mycotoxins fusaproliferin, beauvericin, enniatins, and moniliformin: a review.
The contamination of foods and feed with mycotoxins is a commonly known problem. Intense investigations have been conducted to study the occurrence, toxicity, and recently also the prevention and detoxification strategies of mycotoxins in human and animal food chains. Most of the studies have emphasized on "traditional" mycotoxins, such as aflatoxins, ochratoxin A, and trichothecenes. However, ...
متن کاملBioactive endophytic fungi isolated from Caesalpinia echinata Lam. (Brazilwood) and identification of beauvericin as a trypanocidal metabolite from Fusarium sp.
Aiming to identify new sources of bioactive secondary metabolites, we isolated 82 endophytic fungi from stems and barks of the native Brazilian tree Caesalpinia echinata Lam. (Fabaceae). We tested their ethyl acetate extracts in several in vitro assays. The organic extracts from three isolates showed antibacterial activity against Staphylococcus aureus and Escherichia coli [minimal inhibitory c...
متن کاملNematicidal activity of beauvericin produced by the fungus Fusarium bulbicola.
A nematicide, beauvericin (1), was isolated from cultures of the fungus Fusarium bulbicola, and its structure was identified by spectroscopic analysis. Compound 1 showed nematicidal activities against the pine wood nematode Bursaphelenchus xylophilus and the free-living nematode Caenorhabditis elegans.
متن کاملContamination of Bananas with Beauvericin and Fusaric Acid Produced by Fusarium oxysporum f. sp. cubense
BACKGROUND Fusarium wilt, caused by the fungal pathogen Fusarium oxysporum f. sp. cubense (Foc), is one of the most destructive diseases of banana. Toxins produced by Foc have been proposed to play an important role during the pathogenic process. The objectives of this study were to investigate the contamination of banana with toxins produced by Foc, and to elucidate their role in pathogenesis....
متن کاملCloning and characterization of a novel 2-ketoisovalerate reductase from the beauvericin producer Fusarium proliferatum LF061
BACKGROUND The ketoisovalerate reductase (EC 1.2.7.7 ) is required for the formation of beauvericin via the nonribosomal peptide synthetase biosynthetic pathway. It catalyzes the NADPH-specific reduction of ketoisovaleric acid to hydroxyisovalerate. However, little is known about the bioinformatics' data about the 2-Kiv reductase in Fusarium. To date, heterologous production of the gene KivRFp ...
