Production of new unsaturated lipids during wood decay by ligninolytic basidiomycetes.
Lipids were analyzed by gas chromatography-mass spectrometry for a 7-week in vitro decay of eucalypt wood by four ligninolytic basidiomycetes. The sound wood contained up to 75 mg of lipophilic compounds per 100 g of wood. Hydrolysis of sterol esters, which represented 38% of total wood lipids, occurred during the fungal decay. The initial increase of linoleic and other free unsaturated fatty a...
متن کاملControl of growth of wood decay Basidiomycetes by Trichoderma spp. and other potentially antagonistic fungi
Isolates of Trichoderma, Penicillium, and Aspergillus were tested against Trametes versicolor and Neolentinus lepideus by agar interaction tests and by measuring the toxicity of culture filtrates. Some isolates were able to overgrow and kill both of the decay fungi in agar culture but others were totally ineffective. Although the filtrate from most isolates produced some growth inhibition of th...
متن کاملThe effect of lignin content and lignin modification on Norway spruce wood properties and decay resistance
This thesis describes studies with three different Norway spruce cutting clones in three growing environments differing in soil and climatic conditions within the boreal zone. The main aim was to follow variation in the radial growth rate, wood properties and lignin content and to modify wood lignin with a natural monolignol, coniferyl alcohol, by making use of inherent wood peroxidases. In add...
متن کاملLignin‐Retaining Transparent Wood
Optically transparent wood, combining optical and mechanical performance, is an emerging new material for light-transmitting structures in buildings with the aim of reducing energy consumption. One of the main obstacles for transparent wood fabrication is delignification, where around 30 wt % of wood tissue is removed to reduce light absorption and refractive index mismatch. This step is time c...
متن کاملInterspecific combative interactions between wood-decaying basidiomycetes.
Competition is the most common type of interaction occurring between wood-decaying higher fungi. Since competition for nutrients in organic resources is effectively brought about by competition for space, the common division into interference and exploitation competition is not very appropriate. Fungal competition can be divided into primary resource capture (obtaining uncolonized resources) an...
