BASED ON BIOCHEMICAL AND PHYSIOLOGICAL BEHAVIOR, WHERE IS ASPERGILLUS-EGYPTIACUS BETTER PLACED

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.
