Electron Microscopy of Cellulose Decomposition by Brown-Rot Fungi
Holzforschung, 1983The degradation of isolated cellulose by 11 brown-rot fungi was observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). SEM showed random growth of all the fungi over the fiber surface and that none of the fungi penetrated into the fibers by means of bore holes.

Further studies of the brown-rot fungi
Transactions of the British Mycological Society, 1927Summary A survey is presented of the literature on the nomenclature of the brown-rot fungus generally distributed throughout the fruitgrowing regions of the United States and Canada. The names that have been applied to it are: Sclerotinia fructigena (Pers.) Schrot.; Sclerotinia cinerea (Bon.) Schrot.; Sclerotinia cinerea forma americana Wormald ...

Decomposition of Wood by Brown-Rot Fungi
1989Many different types of organisms deteriorate wood, but the greatest damage is microbial decay caused by fungi (Figures 1 and 2). Fungal decay is by far the most serious type of damage to wood in use, because it can cause structural failure that, at times, is very rapid.

Wood Degradation by Brown-Rot and White-Rot Fungi
2004Elucidating the mechanism of biological wood decay is not only important ecologically due to its role in the carbon cycle, but also due to its economic significance. Research into this fundamental process has resulted in a large number of potential applications in the pulp and paper industry.

Biological Characterization of Poria Indoor Brown-Rot Fungi
hfsg, 1996Pure cultures of the Paria indoor brown-not fungi, Antrodia vaillantii, A.sinuosa, A.serialis, A.xantha and Tyromyces placenta, were studied regarding growth rate, response to temperature, copper tolerance, wood decay and mycelial interactions. Radial growth extension reached from 4-9 mm/d. All fungi were rather resistant to high temperatures.

Efficacy of Pinosylvins against White-Rot and Brown-Rot Fungi
Holzforschung, 1999Summary Three stilbenes, pinosylvin (PS), pinosylvin monomethyl ether (PSM) and pinosylvin dimethyl ether (PSD), were extracted from white spruce (Picea glauca), jack pine (Pinus banksiana), and red pine (Pinus resinosa) pine cones, and their structures were confirmed by spectroscopic and chromatographic (HPLC, GC/MS, NMR and FTIR) analysis.

The ultrastructure of the stroma of the brown rot fungi
Archiv f�r Mikrobiologie, 1969Most of the hyphae forming the medulla of the stroma of the brown rot fungi are 4–7 μ in diameter and contain food reserves in large vacuoles and lipid bodies. Some stromatal hyphae have very thick walls and perform a protective function. Smaller hyphae (1–2 μ in diameter) form a network through the medulla and their structure suggests that they ...

Solid-state fermentation of pine sawdust by selected brown-rot fungi
Enzyme and Microbial Technology, 1989Abstract The effects of selected culture parameters on the solid-state fermentation of radiata pine (Pinus radiata) by the brown-rot fungus Gloeophyllum trabeum were examined. Oxygen concentration is critical for wood decay; a twofold increase was observed when 21% O2 was employed, as compared to 5% O2. The highest yields were obtained with pO2 > 50%.

Biodegradation of Pinus radiata softwood by white- and brown-rot fungi
World Journal of Microbiology and Biotechnology, 2001The weight and component losses of Pinus radiata wood after decay by six species of white-rot and two species of brown-rot fungi for periods varying from 30 to 360 days were evaluated. Three groups of decayed wood samples were identified based on the principal component analysis (PCA) of the data on their weight and component losses.

Decay threshold of acetylated rattan against white and brown rot fungi
International Wood Products Journal, 2012The decay resistance of acetylated rattan was compared to beech and pine wood. Calamus manan grown under rubber tree canopy of different ages (10 and 13 years) was acetylated to different levels by reaction times (0·25–24 h) and was subjected to decay against the white and brown rot fungi, T. versicolor and C. puteana. Protection against decay occurred
