Summary

The effectiveness ofAspergillus differential medium (ADM) for the identification ofAspergillus 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 asA. flavus andA. oryzae, respectively. Strains of the groupsA. clavatus (76),A. glaucus (100),A. fumigatus- (9),A. niger- (6),A. candidus- (3),A. wentii-(1),A. versicolor (23),A. nidulans (6),A. ustus (1) andA. terreus (1) gave negative results. Positive results were shown by 9 strains of theA. 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.

Zusammenfassung

Es wurde die Eignung desAspergillus-Differentialmediums (ADM) zur Identifizierung einer Anzahl vonAspergillus-Stämmen untersucht. Das hellgelborange Pigment produzierten 205 (88,7%) aus 231 Stämmen, resp. 97 (61,3%) aus 158 Stämmen, die während der routinemäßigen mykologischen Arbeit alsA. flavus, resp.A.oryzae bestimmt waren. Negativ waren die Stämme der GruppenA. clavatus (76),A. glaucus (100),A. fumigatus (9),A. niger (6),A. candidus (3),A. wentii (1),A. versicolor (23),A. nidulans (6),A. ustus (1) undA. terreus (1). Positiv waren 9 Stämme derA. ochraceus-Gruppe.

Aufgrund unserer Ergebnisse können wir bestätigen, daß das ADM-Substrat einen guten Beitrag zur Identifizierung potentieller Alfatoxinproduzenten in Lebensmitteln bietet. Es ist jedoch zweckmäßig, dieses Substrat gleichzeitig mit anderen üblichen Selektionssubstraten für Schimmelpilze zu verwenden.
