title: [The effectiveness of an (Aspergillus) differential medium in the course of the mycological examination of foods].
abstract: The effectiveness of Aspergillus differential medium (ADM) for the identification of Aspergillus strains was tested. The bright yellow-orange pigment was produced by 205 (88,7%) of 231 strains and resp. 97 (61,3%) of 158 strains, which during routine mycologic diagnostic as A.flavus and A.oryzae, respectively. Strains of the groups A.clavatus (76), A.glacus (100), A.fumigatus-(9), A.niger-(6), A.candidus-(3), A.wentii-(1), A.versicolor (23), A.nidulans (6), A.ustus (1) and A.terreus (1) gave negative results. Positive results were shown by 9 strains of the A.ochraceus group. It was shown that for the mycological examination of certain foods the ADM medium can make an important contribution to the identification of potential aflatoxin producers. However it is better not to use the ADM medium only alone but also together with other customary mycological nutrient media.
