Abstract

A plate assay using the Fe(II) selective dye, ferrozine, for detecting wood-rot fungi with Fe(III) reductive abilities, was developed. The assay is fast, simple and, in most cases, more sensitive than the corresponding liquid medium test. The brown rot fungi, Gloeophyllum trabeum and Laetiporeus sulphureus, displayed higher iron reductive capabilities than white rot fungi, Trametes versicolor, Ganoderma australe and Ceriporiopsis subvermispora.
