Mold spectrum of four cereal brands of the German crop 1995

Abstract

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 wheat and two winter rye brands which showed the highest EPS-concentration was detected on maltsalt agar (NaCl 5%). Surface disinfection with 1% NaOCl for the determination of the internal mycoflora caused a significant reduction in number and kind of fungi. However, the mycoflora of all samples was dominated by fungi of the genera Alternaria spp. and Cladosporium spp., Aureobasidium pullulans, Fusarium spp. and Epicoccum purpurascens (in decreasing order) occurred to a minor extent. A possible contamination of the cereal grains with mycotoxins of Alternaria and Cladosporium is discussed.

Investigation of stored wheat mycoflora, reporting theFusarium cf.langsethiae in three provinces of Iran during 2007

“…and Cladosporium spp. The result of this study is in accordance with other studies (Furlung et al, 1995;Weidenboner et al, 1997;Krysinska-Traczyk et al, 2003;Saberi-Riseh et al, 2004). The grains obtained from Mazandaran province were contaminated more by Aspergillus spp., Penicillium spp.…”

Distribution of microbial contamination within cereal grains

“…However, to our knowledge, there are no studies looking at the distribution of contamination in cereals. If cereal contamination were to be concentrated towards the surface of the kernel, the knowledge of the location of these microorganisms would allow us to determine the degree of debranning necessary to remove the microbial contamination without the need of using any chemical or irradiation method (Ramakrishna, Lacey, & Smith, 1991;Weidenborner, Berleth, Kramer, & Kunz, 1997).…”
