Abstract

The white rot fungus Inonotus weirii produced an extracellular peroxidase which was excreted in association with cell growth and in the absence of an inducer. Production of peroxidase was greatly influenced by the carbon and nitrogen source.
The highest activities were obtained on glucose-and xylose-based media containing a combination of ammonium nitrate, yeast extract and distiller's spent grain as nitrogen source. The enzyme produced had a molecular weight of 42000, was stable in the pH range 3–8 at room temperature and had optimal activity at pH 3.
The fungus Inonotus weirii could be a potential producer of peroxidase for industrial applications in spite of its rather slow production rate.
