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 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.

Evaluation of beauvericin genotoxicity with the chromosomal aberrations, sister-chromatid exchanges and micronucleus assays

Ecotoxicology and Environmental Safety, 2010
Beauvericin, a naturally occurring contaminants of food and feeds, has been implicated in several mycotoxicoses; however, there is little information on its genotoxicity.

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.

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.

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.

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 ...

Evaluation of enniatins A, A1, B, B1 and beauvericin in Portuguese cereal-based foods

Food Additives and Contaminants - Part A Chemistry, Analysis, Control, Exposure and Risk Assessment, 2012
Sixty-one samples of Portuguese cereal-based foods were analysed for the occurrence of emerging mycotoxins called enniatins (A, A1, B and B1) and beauvericin.
