Yeast and Bacteria as Biological Control Agents Against Fungal Discolouration of Pinus sylvestris Blocks in Laboratory-Based Tests and the Role of Antifungal Volatiles

摘要

This paper reports on the use of yeast as biological control agents against mould and blue-stain fungi in laboratory-based Pinus sylvestris sapwood wood block incubation tests. All 5 yeast isoaltes tested sig- nificantly reduced discolouration of wood surfaces by moulds and most were also effective against stain- ing fungi. The 2 most promising yeast isolates also significantly reduced radial growth of selected mould and stain fungi in vitro solely through the liberation of volatile compounds.
