DETECTION AND DIFFERENTIATION OF PORIA INDOOR BROWN-ROT FUNGI BY POLYACRYLAMIDE-GEL ELECTROPHORESIS

Species of the Poria group causing brown rot of wood in buildings and with similar morphological appearance and biology, namely Antrodia vai llantii, A. serialis, A. sinuosa, A. xantha, and Tryomyces placenta, w ere investigated by SDS polyacrylamide gel electrophoresis. Different cultures of A. vaillantii showed a species-specific protein profile se parating the fungus from A. serialis, A. sinuosa and A. xantha and fro m T. placenta. The method also differentiated these pore fungi from th e dry rot fungus Serpula lacrymans and detected misidentifications.
