Biosynthesis of fusarochromanone and its monoacetyl derivative by Fusarium equiseti.
One fluorescent compound previously named TDP-2 was isolated and purified from a rice culture of Fusarium equiseti (Alaska 2-2). Mass spectral and nuclear magnetic resonance data indicated that it is a C-3'-N-acetyl derivative of fusarochromanone, a newly discovered mycotoxin. Time course studies of synthesis of these two compounds on autoclaved rice and Czapek-Dox medium enriched with soybean ...
متن کاملAntibiotic produced by Fusarium equiseti NRRL 5537.
Fusarium equiseti NRRL 5537 grown on an autoclaved white corn grit medium for 3 to 4 weeks at room temperature produced a substance in excess of 5 g/kg of substrate that inhibited some gram-positive bacteria including mycobacteria. Most Bacillus subtilis, Mycobacterium phlei, and Staphylococcus aureus strains were inhibited when 1 mug of the antibiotic per ml was incorporated into the culture m...
متن کاملNatural occurrence of the mycotoxin fusarochromanone, a metabolite of Fusarium equiseti, in cereal feed associated with tibial dyschondroplasia.
The mycotoxin fusarochromanone, a metabolite of Fusarium fungi, is able to induce tibial dyschondroplasia (TD) in chickens under experimental conditions. On the basis of health surveillance data on TD, two broiler farms with TD prevalence rates of up to 56% were identified. In the corresponding pelleted feed samples, fusarochromanone was detected in all 12 samples analyzed by column purificatio...
متن کاملFusarium incarnatum/equiseti hemodialysis graft infection
Hemodialysis graft infections typically occur as a result of contamination by skin flora at the time of insertion or become secondarily infected after high-grade bacteremia. Infection of implanted vascular devices with filamentous fungi is rare. We report a case of infection of an implanted polytetrafluoroethylene dialysis graft with Fusarium incarnatum/equiseti that did not grow in cultures of...
متن کاملEquisetin, an antibiotic from Fusarium equiseti NRRL 5537, identified as a derivative of N-methyl-2,4-pyrollidone.
Sir: Various species of Fusarium produce toxins that are implicated in mycotoxicoses in several areas around the world. During a survey of this genus, we found that one species, Fusarium equiseti (CORDA) SACCARDO, produced an antibiotic in yields of 5 g/kg when grown on corn grit medium at room temperature (20-.24°C). Production, isolation and biological activity of the antibiotic, assigned the...
