MOLD SPECTRUM OF 4 CEREAL BRANDS OF THE GERMAN CROP 1995

The concentration of extracellular polysaccharides (EPS) of 80 cereal grain samples of the German harvest 1995 was investigated. In addition to this, the total as well as the inherent mycoflora of two winter wh eat and two winter rye brands which showed the highest EPS-concentrati on was detected on maltsalt agar (NaCl 5%). Surface disinfection with 1% NaOCl for the determination of the internal mycoflora caused a sign ificant reduction in number and bind of fungi. However, the mycoflora of all samples was dominated by fungi of the genera Alternaria spp. an d Cladosporium spp., Aureobasidium pullulans, Fusarium spp. and Epicoc cum purpurascens (in decreasing order) occurred to a minor extent. A p ossible contamination of the cereal grains with mycotoxins of Alternar ia and Cladosporium is discussed.
