title: Repressible alkaline phosphatase in Aspergillus niger.
abstract: ALP from A. niger is a) P1 repressible enzyme; b) stimulated by addition of Zn++ to the growth medium, and c) that EDTA inhibits the enzyme reversibly, which could be restored by addition of Zn++ and perhaps Mg++. This property is in contrast to the enzyme from N. crassa, which is independent of any metal requirement.
