It has previously been shown that the biosynthesis of the mycotoxins ochratoxin A and B and of citrinin by Penicillium is regulated by light. However, not only the biosynthesis of these mycotoxins, but also the molecules themselves are strongly affected by light of certain wavelengths. The white light and blue light of 470 and 455 nm are especially able to degrade ochratoxin A, ochratoxin B and...

A rapid assay procedure was developed for mycotoxin citrinin in corn using liquid-liquid extraction (LLE) cartridges. Ground corn was extracted with methylene chloride and 0.5 N phosphoric acid. The extract was added to an LLE cartridge containing a diatomaceous-earth adsorbant, previously impregnated with sodium bicarbonate solution. After aspiration to dryness, the cartridge was eluted with m...

AIMS To study the influence of culture preservation methods and culture conditions on the production of the mycotoxins patulin and citrinin by Penicillium expansum. METHODS AND RESULTS Ten strains of Penicillium expansum were preserved using subculture and maintenance at 4 degrees C, mineral oil, drying on silica gel and freeze-drying. Patulin and citrinin production was assessed on yeast ext...

Citrinin is a nephrotoxic mycotoxin produced by several species of the genus and Monascus. Citrinin is generally formed after harvest and occurs mainly in stored grains. efficacy of different concentrations of aqueous leaf extracts of Rhazya stricta Decne and Cleome amblyocarpa two fungal strains Penicillium notatum and Aspergillus niger and fungal biomass by the isolates was suppressed, depend...

Although single genes underlying several evolutionary adaptations have been identified, the genetic basis of complex, polygenic adaptations has been far more challenging to pinpoint. Here we report that the budding yeast Saccharomyces paradoxus has recently evolved resistance to citrinin, a naturally occurring mycotoxin. Applying a genome-wide test for selection on cis-regulation, we identified...

Citrinin is the one of the well-known mycotoxins, which is possibly spread all over the world. The graded doses of citrinin (1, 3 and 5 ppm CIT in feed) in female Wistar rats 10 weeks prior to mating, during mating and during organogenesis resulted in resorptions and post implantation losses, decreased fetal body weights and crown-rump lengths in fetuses of all groups. Various developmental ano...

The present study investigated the effects of agitation speed, N (200, 500, 600 or 700 rpm), and dissolved oxygen concentration, C (120, >70, 70, 60, 10 or 10%), on red pigment and citrinin production by Monascus purpureus ATCC 36928, cultivated in liquid medium by a batch process. The gas flow rate was the same for all runs with C controlled by means of the incoming gas composition control (ai...

BACKGROUND Red yeast rice (RYR) is a widely available dietary supplement used by millions of patients as an alternative therapy for hyperlipidemia. It contains 14 active compounds called monacolins that inhibit hepatic cholesterol synthesis. Although studies have suggested that some formulations of RYR may be effective and safe for lipid lowering, monacolin levels are not standardized among mar...
