Fiber dimensions , lignin and cellulose content of various plant materials and their suitability for paper production
Fiber dimensions and lignin and cellulose content of various highly productive, non-wood plants and agricultural residues were examined to assess their suitability for paper production. Plants like kenaf (Hibiscus cannabinus L.) and giant reed (Arundo donax L.) internodes gave very good derived values, especially slenderness ratio, which is directly comparable to some softwood and most hardwood...
متن کاملDetermination of nutritional value of four plant species (Malcolmia africana, Plantago lanceolata, Phlomis cancellata, and Klasea latifolia) in rangelands of Bala Jam, Torbat-e Jam
Due to the extensive area and biodiversity, rangelands contribute to meeting the nutritional requirements of grazing livestock; Therefore, a study was conducted to investigate the nutritional value of four range species including Malcolmia africana, Plantago lanceolata, Phlomis cancellata, and Klasea latifolia in the mountainous rangelands of Torbat-e Jam. The sampling of plants was randomly do...
متن کاملDetermination of Lignin Content in Acacia Spp. Using Near-infrared Reflectance Spectroscopy
Near infrared (NIR) spectroscopy method was introduced to measure the lignin content in Acacia species. Acid-soluble lignin, Klason lignin, and total lignin contents from 78 wood meal samples of Acacia spp. trees grown in Guangxi province with different ages, height, and families were measured by wet chemistry. NIR spectra were also collected using a Bruker MPA spectrometer within 4000-12500cm ...
متن کاملAcetylation of wood – A review
Wood is a porous three dimensional, hydroscopic, viscoelastic, anisotropic bio-polymer composite composed of an interconnecting matrix of cellulose, hemicelluloses and lignin with minor amounts of inorganic elements and organic extractives. Some, but not all, of the cell wall polymer hydroxyl groups are accessible to moisture and these accessible hydroxyls form hydrogen bonds with water. As the...
متن کاملDetermination of lignin-modifying enzymes (LMEs) in Hyphodermella species using biochemical and molecular techniques
White-rot basidiomycetes are one of the most important lignolytic microorganisms. These fungi have been reported to secrete three main classes of lignin degrading enzymes: lignin peroxidases (LiPs), manganese peroxidases (MnPs) and laccases. In this study, for the first time the lignin degrading capability of two plant pathogens i.e. Hyphodermella rosae and H. corrugata was evaluated using both...
