Ma. Ismail et Aa. Zohri, CONFIRMATION OF THE RELATIONSHIPS OF ASPERGILLUS-EGYPTIACUS AND EMERICELLA-NIDULANS USING PROGESTERONE TRANSFORMATION, Letters in applied microbiology, 18(3), 1994, pp. 130-131
Isolates of Emericella nidulans (7 isolates), Aspergillus egyptiacus (
7) and A. versicolor (5) were tested for their ability to transform pr
ogesterone. Consistent results were obtained between isolates of the s
ame species. Whilst A. egyptiacus and E. nidulans possessed the enzyme
system catalysing the transformation of progesterone into 11-alpha-hy
droxyprogesterone, A. versicolor did not. Thus, progesterone transform
ation could be considered as further diagnostic evidence that A. egypt
iacus is related to the Emericella group.
