Summary
To determine the extent of mould contamination and the mycoflora of some cereals and cereal products such as barley, corn, rice, wheat,bulgur and flour, a total of 242 samples were collected from different agricultural regions of Turkey. Mould contamination of samples varied between 103 and 106 colonies/g. Moisture contents of the samples were found to range between 12.65 and 13.97%. Most commonly isolated moulds werePenicillium (46%),Aspergillus (22%),Cladosporium (9%),Rhizopus (6%),Aureobasidium (5%) andEurotium (4%) species. Results have been evaluated to assess the kinds of mycotoxins that can be produced by these mycoflora and the effect of seed moisture on growth of the relevant fungi.
Résumé
Un total de 242 échantillons a été récolté dans différentes régions agricoles de Turquie, afin de déterminer l'étendue de la contamination par moisissures ainsi que la mycoflore de certaines céréales et produits céréaliers tels l'orge, le maïs, le riz, le froment, le ‘bulgur’ et la farine. La contamination par moisissures a varié de 103 à 106 colonies par g. L'humidité des échantillons variait entre 12.65 et 13.97%. Les moisissures les plus communément isolées sont lesPencillium (46%), lesAspergillus (22%), lesCladosporium (9%), lesRhizopus (6%), lesAureobasidium (5%) et lesEurotium (4%). Les résultats ont été examinés pour déterminer les types de mycotoxines qui pouvaient être produites par cette mycoflore et l'effet de l'humidité de la graine sur la croissance des moisissures idoines.
Resumen
A fin de determinar la extensión de la contaminación por mohos, y la microflora presente en algunos cereales y derivados tales como; avena, maíz, arroz, trigo, ‘bulgar’ y harina, se recogieron 242 muestras de distintas regiones agrícolas de Turquía. La contaminación por mohos varió entre 103 y 106 colonias/g, y el porcentaje de humedad entre 12.65 y 13.97%. Los mohos que se aislaron con mayor frecuencia fueron especies dePenicillium (46%),Aspergilus (22%),Cladosporium (9%),Rhizopus (6%),Aureobasidium (5%) yEurotium (4%). Los resultados se han evaluado para determinar el tipo de micotoxinas que esta micoflora puede producir y el efecto de la humedad de las semillas en el crecimiento de los hongos más importantes.
