title: Production of catalase by fungi growing at low pH and high temperature.
abstract: More than 100 fungi were isolated from cultures at pH 1.0 or 2.5 and 42-45 degrees C, and the production of catalases was investigated. Four strains produced a catalase with high stability at pH 2.0, and three of them produced two extracellular catalases and four intracellular catalases. In these four intracellular catalases, two catalases were similar to extracellular catalases in enzymatic properties and pI. These strains belonged to Aspergillus niger.
