Polyacrylamide gel electrophoretic mobility of alkaline proteinase produced by Aspergillus flavus isolated from a penguin.

The electrophoretic mobility of alkaline proteinase produced by four isolates from a penguin (Spheniscus magellanicus) was same in all of them and was consistent with that of Aspergillus (A.) flavus NRRL 1957 used as a reference strain, but not consistent with that of A. parasiticus NRRL 2999. Therefore, four isolates were confirmed as A. flavus.
