A beauvericin hot spot in the genus Isaria

Mycological Research, 2009
Beauvericin is a naturally occurring cyclohexadepsipeptide originally described from Beauveria bassiana but also reported from several Fusarium species as well as members of the genus Isaria. Twenty-six isolates of Isaria species and its Cordyceps teleomorph, and ten taxonomically close strains including Beauveria, Nomuraea and Paecilomyces species ...

Beauvericin Production by Fusarium Species

Applied and Environmental Microbiology, 1998
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 phytopathogenic Fusarium species ( Fusarium proliferatum , F. semitectum

Beauvericin Decreases Cell Viability of Wheat

Chemistry & Biodiversity, 2009
AbstractRecently, beauvericin (BEA) has been recognized as an important toxic compound synthesized by several Fusarium strains, infecting maize, wheat, and rice, worldwide. The effects of BEA on mammalian cells have been studied; however, its effects on the function of host plant cells are largely unknown.

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.

Effects of beauvericin on the blood cells of Bombyx mori

Journal of Invertebrate Pathology, 2023
In this study, silkworms were treated by injection of the bioactive depsipeptide beauvericin (BEA) to explore its effect on the cellular immunity of larvae of the silkworm Bombyx mori. The results showed that: The LC50 of BEA for silkworms on the 3rd day of the 4th instar was 362.36 µM.

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.

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.

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.

The binding of barium and calcium ions by the antibiotic beauvericin

Biochemical and Biophysical Research Communications, 1974
Abstract 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.

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.
