Effect of commonly used cosmetic preservatives on skin resident microflora dynamics.

Human skin is populated by various microorganisms, the so-called microbiota, such as bacteria, viruses, yeasts, fungi, and archaea. The skin microbiota is in constant contact with the surrounding environment which can alter its eubiotic state. Recently it has been also observed that the application of cosmetic products can alter the balance of the skin microbiota.

Molecular Identification and Mycotoxin Production by Species Occurring on Durum Wheat, Showing Black Point Symptoms.

Black point is a fungal disease of wheat, mainly associated with mycotoxigenic species. Affected wheat kernels are characterized by dark brown discolouration of the embryo region and reduction of grain quality. Potential risk is the possible accumulation of mycotoxins, alternariol (AOH), alternariol-monomethyl ether (AME), tenuazonic acid (TA), and altenuene (ALT), provided by haemato-toxic, genotoxic, and mutagenic activities.
