Biodegradability of Extractives in Sapwood and Heartwood from Scots Pine by Sapstain and White Rot Fungi
نویسندگان
چکیده
Wood extractives cause pitch problems in pulp and paper manufacture. Extractives are low-molecular weight lipophilic components in wood consisting mainly of triglycerides, waxes, steryl esters, sterols, free long chain fatty acids and resin acids (Fengel and Wegener 1989a). The deposits of wood extractives associated with fibers, inorganic salts and additives, technically referred to as pitch, disrupt the runnability of paper-making machinery and reduce strength and brightness of pulp (Allen 1980).

PUBLICATION III Decay resistance of sapwood and heartwood of untreated and thermally modified Scots pine and Norway spruce compared with some other wood species
Thermal modification has been developed for an industrial method to increase the biological durability and dimensional stability of wood. In this study the effects of thermal modification on resistance against softand brown-rot fungi of sapwood and heartwood of Scots pine and Norway spruce were investigated using laboratory test methods. Natural durability against soft-rot microfungi was determ...
متن کاملAnalysis, pretreatment and enzymatic saccharification of different fractions of Scots pine
BACKGROUND Forestry residues consisting of softwood are a major lignocellulosic resource for production of liquid biofuels. Scots pine, a commercially important forest tree, was fractionated into seven fractions of chips: juvenile heartwood, mature heartwood, juvenile sapwood, mature sapwood, bark, top parts, and knotwood. The different fractions were characterized analytically with regard to c...
متن کاملInfluence of Post-extraction on Photostability of Thermally Modified Scots Pine Wood during Artificial Weathering
The photo-stabilizing effect of post-extraction was evaluated for thermally modified wood. Extracted and non-extracted thermally modified Scots pine (Pinus sylvestris L.) samples were exposed in a xenon weather-ometer for 1008 h, and the surface color and chemical changes were characterized using a chroma meter, attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), an...
متن کاملThe GSTome Reflects the Chemical Environment of White-Rot Fungi
White-rot fungi possess the unique ability to degrade and mineralize all the different components of wood. In other respects, wood durability, among other factors, is due to the presence of extractives that are potential antimicrobial molecules. To cope with these molecules, wood decay fungi have developed a complex detoxification network including glutathione transferases (GST). The interactio...
متن کاملEvaluation of Importance of Sapwood Senescence on Tree Growth Using the Model Lignum
The effects of two alternative formulations of sapwood senescence on the behavior of model LIGNUM (with parameter values adjusted for Scots pine growing southern Finland) were studied. The two alternatives were: autonomous sapwood senescence assuming a maximum age for the tree ring and sapwood senescence that is controlled by the mortality of foliage. For the latter alternative two hypothetical...
