Unique preservative tolerance in Tyromyces palustris

Fungal tolerance to wood preservatives has been critically important for many years. The tolerance of type cultures to common wood preservatives is, in fact, noted in the AWPA Standards [1]. Gloeophyllum trabeum Mad-617, for example, is particularly tolerant to phenolic and arsenic compounds. One important group of decay fungi that has been studied extensively are those that are copper tolerant such as Postia placenta MAD-698, which is particularly tolerant to copper and zinc compounds [1]. Recently, Tyromyces palustris and Serpula lacrymans, the European dry rot fungus, have also been shown to be copper tolerant.
