Supercritical fluid extraction of Beauvericin from maize

Talanta, 2004
Beauvericin (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.

Beauvericin induced erythrocyte cell membrane scrambling

Toxicology, 2011
Beauvericin 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.

Effects of beauvericin on Schizaphis graminum (Aphididae)

Journal of Invertebrate Pathology, 2002
The effects of beauvericin, a toxic fungal metabolite common contaminant of maize and wheat, on aphid fitness were studied in three consecutive generations of females. Aphids were reared on wheat leaves inserted into a sandy substratum wetted with a solution of beauvericin.

Beauvericin: Chemistry, Biology and Significance

2002
Mycotoxin contamination of cereal crops is of a worldwide concern since about 35% of cereal crop products contain measurable amount ofmycotoxins. Beauvericin is one toxic metabolite recently reported as product of some important phytopathogenic Fusarium species.

Mechanisms of beauvericin toxicity and antioxidant cellular defense

Toxicology Letters, 2016
Beauvericin (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 ...

Beauvericin and enniatin: emerging toxins and/or remedies?

World Mycotoxin Journal, 2010
Beauvericin (BEA) and enniatins (ENN) are emerging Fusarium mycotoxins that are known to contaminate food and feed. BEA- and ENN-mediated cytotoxicity towards various mammalian and cancer cell lines is only partly understood yet and engages several cellular targets and molecular mechanisms.

Production of beauvericin byFusarium proliferatum from maize in Italy

Mycotoxin Research, 1994
Beauvericin (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,

Chemical reduction of the mycotoxin beauvericin using allyl isothiocyanate

Food and Chemical Toxicology, 2012
Beauvericin (BEA) is a bioactive compound produced by the secondary metabolism of several Fusarium strains and known to have various biological activities. This study investigated the reduction of BEA present in the concentration of 25mg/kg on a solution model (phosphate buffer saline at pH 4 and 7) and in wheat flour using allyl isothiocyanate (AITC ...

Fusaproliferin, beauvericin and enniatins: occurrence in food – a review

World Mycotoxin Journal, 2012
The present review summarises data on the prevalence and concentration of fusaproliferin, beauvericin and enniatins in small grains, maize and processed grain-based foods. These fungal secondary metabolites possess interesting biological activities and are presently often referred to as 'emerging mycotoxins'. They have been considered as less important

Ciclohexadespipeptide beauvericin degradation by different strains of Saccharomyces cerevisiae

Food and Chemical Toxicology, 2013
The interaction between the mycotoxin beauvericin (BEA) and 9 yeast strains of Saccharomyces cerevisiae named LO9, YE-2, YE5, YE-6, YE-4, A34, A17, A42 and A08 was studied. The biological degradations were carried out under aerobic conditions in the liquid medium of Potato Dextrose Broth (PDB) at 25°C for 48 h and in a food/feed system composed of corn
