title: Acidophilic fungus, Teratosphaeria acidotherma AIU BGA-1, produces multiple forms of intracellular β-galactosidase.
abstract: Teratosphaeria acidotherma AIU BGA-1 isolated from an acidic and high temperature hot spring produced four intracellular β-D-galactosidases with different pH activity profiles, in which three forms were acidophilic and stable from extremely acidic to neutral pH region. The other one was alkalophilic and unstable in the acidic pH region.
