Aa. Zohri et Ma. Ismail, BASED ON BIOCHEMICAL AND PHYSIOLOGICAL BEHAVIOR, WHERE IS ASPERGILLUS-EGYPTIACUS BETTER PLACED, Folia microbiologica, 39(5), 1994, pp. 415-419
Physiological and biochemical properties were tested in 45 isolates of
Aspergillus egyptiacus (16 isolates), Emericella nidulans (16) and As
pergillus versicolor (13). The three fungal species exhibited common a
nd similar features. The big similarity between A. egyptiacus and E. n
idulans was greater than between A. egyptiacus and A. versicolor. It i
ncluded the inability to produce base either from sodium citrate or la
ctic acid media, growth at 45 degrees C (thermophilicity), and product
ion of very similar pigmentations on Aspergillus flavus and parasiticu
s agar. A. eqyptiacus is therefore better placed in the Aspergillus ni
dulans-Emericella assemblage.
