“…The lignin content of mature galls was determined by extraction with neutral detergent (Van Soest et al 1991) to isolate cell walls. These were subsequently subjected to a two-stage acid hydrolysis (Kaar et al 1991) to determine acid-insoluble (klason) lignin. Acid-soluble lignin in the filtrate was quantified by spectroscopy (TAPPI 1989).…”

Abstract:Gall inducers are favoured as biocontrol agents of weeds because they tend to have a narrow host range. Six insect and one nematode gall inducer used in Canada are described in terms of their biology, gall morphology, gall physiology, and effectiveness in weed control. The species differ in plant organ attacked, requirement for moisture, whether the galls are induced by secretions or by severing xylem, and effectiveness, which in part relates to the ability of the gall to import nutrients. The most powerful galls divert assimilates from other sinks via a gall's vascular system joined to that of their host. One of our examples also has mechanisms to compensate for reduction of turgor during drought. Two of the gall inducers enhance their nutrient supply by severing xylem in a plant nutrient sink. One, in the short-term sink of a thistle capitulum, obtains about a quarter of its assimilates at the expense of other capitula. The other, in the long-term sink of a rosette root, approximately halves seed production. Hypotheses are presented to explain various aspects of gall development and function.

“…Sugar analysis of aspen before and after heat treatment with saturated steam at 2208C in a closed system for 8 minutes is greater than that from softwoods, probably due to the greater content of acetyl groups in hardwoods which release acetic acid during heat treatment which contributes to the acid hydrolysis (MacLean 1951, Millett and Gerhards 1972, Hillis 1975. Subsequently, the monomeric sugar units are dehydrated to aldehydes, furfural being formed from pentoses and hydroxymethylfurfural from the dehydration of hexose sugar units (Burtscher et al 1987, Kaar et al 1991, Ellis and Paszner 1994. Several other investigators like Burmester (1973Burmester ( , 1975, Popper et al (2005), Boonstra et al (2007), Welzbacher et al (2007) and Pfriem et al (2010) have shown that the reduced hygroscopicity accompanies increased dimensional stability and increased durability.…”

“…The total mass balance in these varied materials is the summative analysis of the carbohydrates disclosure into their derivatives together with lignin, extractives, and ash contribution [6][7][8]. Therefore, a chemical analysis including determination of the dry matter, elements composition and contents of ash, glucan, xylan, mannan and lignin was performed.…”

Abstract. In pulp and paper industry biomass rich in energy is represented by pulping liquors, wood wastes, sludge and rejects. Many pulp and paper mills produce more than half of their energy needs from biomass fuels recovered from solid pulp and paper wastes. The end-products of conversion of these wastes are solid, liquid or gaseous fuels and moreover, in most cases, the valuable and ecological fertilizer. The proper method of biomass conversion depends on its structure and chemical composition, which includes hemicellulose, cellulose and lignin content.. Pulp and paper industry generate a lot of quantities of valuable biomass as wastes in all stages of the process. Therefore, this paper reviews the current state of using waste from pulp and paper industry as a fuel for energy purposes. For investigation, the materials from four different types of pulp waste were used. Pulp waste I contained knots and barks and was a product of chemical and semi-chemical pulp processes and of mechanical pulp manufacture, pulp waste II contained final fiber waste sludge from kraft mill, pulp waste III contained fiber sludge from board mill and pulp waste IV contained final fiber waste sludge from board mill. The article contains a description of physical properties of pulp wastes such as: moisture content, density, gross and net calorific values. A chemical analysis includes determination of dry matter, element composition and contents of ash, glucan, xylan, mannan and lignin. It was found that residues from mechanical and chemical pulping varied in the origin and stage of production, had similar chemical composition, differed in a narrow range. Pulp waste materials are rich in sugars of above 52 %, reaching a value of approximately 71 %, depending on the sample taken at different stages of processing.Net calorific values for all tested raw materials were high in the range from 19.8 to 20.5 MJ·kg -1 and should be considered as feedstock suitable to generate enough energy.
