Penicillium verrucosum, P. nordicum and Aspergillus carbonarius are three important ochratoxin A producing species. P. verrucosum is in addition able to produce citrinin. It has been shown earlier that P. nordicum is adapted to NaCl rich environments like salt rich dry cured foods or even salines. In this organism, the biosynthesis of ochratoxin A plays an adaptive role in this habitat. P. verr...

Antifungal activity of naftifinc (SN 105-843 gel) a napthyle alkyleamine derivative, was measured in vitro against freshly isolated cultures of dermatophytie fungi. Using appropriate concentrations of naftifine, its antifungal activity was compared with the same concentrations of griseofulvin against Trichophyton rubrum, Trichophyton mentagrophytes, Trichophyton violaceum, Trichophyton tonsuran...

The aim of this research was to use a polyphasic approach to differentiate Penicillium verrucosum from Penicillium nordicum, to compare different techniques, and to select the most suitable for industrial use. In particular, (1) a cultural technique with two substrates selective for these species; (2) a molecular diagnostic test recently set up and a RAPD procedure derived from this assay; (3) ...

Conidia of Aspergillus fumigatus, Aspergillus flavus, Aspergillus niger, Penicillium brevi-compactum, Penicillium frequentans, Penicillium spinulosum, and Penicillium verrucosum var. cyclopium were subjected to partition at varying pH values in an aqueous two-phase system containing charged polyethylene glycol. In the system, the partition behavior of the conidia of the Penicillium species vari...

Contamination of maize and barley grain during storage by the toxigenic fungi Aspergillus flavus (A. flavus) Penicillium Verrucosum (P. verrucosum) is both an economic a public health problem, especially in less industrialized countries. Peracetic acid (PA) compound used for disinfection food contact surfaces. Unlike other disinfectants, it leaves no toxic residues its decomposition products (C...

Ochratoxin A (OTA) is a secondary metabolite produced by filamentous fungi of the genera Aspergillus and Penicillium present in a wide variety of foodstuffs. The most relevant OTAproducing species are Penicillium verrucosum (P. verrucosum), Aspergillus ochraceus (A. ochraceus), A. niger and A. carbonarius due to their prevalence in foodstuffs (cereals, grapes, coffee, etc.) and the number of st...
