Supercritical fluid extraction of Beauvericin from maize
Talanta, 2004Beauvericin (BEA), a supercritical fluid extraction with supercritical carbon dioxide from maize was investigated. Extraction efficiencies under several different extraction conditions were examined. Pressure, temperature, extraction time, organic modifier and water matrix content (10%) were investigated.

Mechanisms of beauvericin toxicity and antioxidant cellular defense
Toxicology Letters, 2016Beauvericin (BEA) is a secondary metabolite produced by many species of fungus Fusarium. This study determines the injury (cell viability, cell proliferation, mitochondrial membrane potential, cell death and DNA damage) and the intracellular defense mechanisms (catalase and superoxide dismutase) in Chinese Hamster ovary (CHO-K1) cells after BEA ...

Nematicidal Activity of Beauvericin Produced by the Fungus Fusarium bulbicola
Zeitschrift Fur Naturforschung - Section C Journal of Biosciences, 2010 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 freeliving nematode Caenorhabditis elegans.

Beauvericin induced erythrocyte cell membrane scrambling
Toxicology, 2011Beauvericin is a mycotoxin with antiviral, antibacterial, nematicidal, insecticidal, cytotoxic, and apoptotic activity. Similar to nucleated cells erythrocytes may undergo suicidal death or eryptosis, which is characterized by cell shrinkage and phosphatidylserine exposure at the erythrocyte surface.

The binding of barium and calcium ions by the antibiotic beauvericin
Biochemical and Biophysical Research Communications, 1974Abstract The ion-transporting antibiotic beauvericin has been shown to have a high affinity for calcium and barium ions in addition to the more usual affinity for monovalent cations. As judged by crystallization, extraction into organic solvent, and U-tube transport the cation selectivity is Rb>Ba>K>Na⪢Ca⋙Li.

Production of beauvericin byFusarium proliferatum from maize in Italy
Mycotoxin Research, 1994Beauvericin (BEA), a toxic cyclodepsipeptide, was purified from corn kernel cultures of a toxigenic strain ofFusarium proliferatum, Isolated from corn ear rot in northern Italy (45 mg/kg dry culture). The strain, designed ITEM-1503, also produced fumonisin B, (2,250 mg/kg dry culture), and moniliformin (150 mg/kg dry culture). Thin-layer chromatography,

Occurrence of enniatins and beauvericin in 60 Chinese medicinal herbs
Food Additives & Contaminants: Part A, 2014A total of 60 Chinese medicinal herbs were examined for contamination of the emerging Fusarium mycotoxins enniatins (ENNs) A, A1, B, B1 and beauvericin (BEA). The herbs under study are commonly used in China as both medicines and food. The dried samples of herbs were randomly collected from traditional Chinese medicine stores in Zhejiang province ...

Beauvericin and divalent cations: Crystal structure of the barium complex
Biochemical and Biophysical Research Communications, 1975Abstract The molecular structure of the 2:2 complex of the cyclohexadepsipeptide antibiotic beauvericin with barium picrate has been determined by X-ray crystallography. The structure serves to confirm previous observations on the bimolecular behavior of beauvericin and of the ions transported by beauvercin.
