DETERMINATION OF CELLULOSE IN STRAW HOLOCELLULOSE

Canadian Journal of Research, 1949
Hydrolysis of wheat, oat, rye, and flax holocelluloses with 0.5% sulphuric acid for one hour at 100 °C. gave a residue that was quantitatively equal to the Cross and Bevan cellulose from the same straws. The hydrolyzed holocellulose residue contained more lignin and less pentosan than the corresponding Cross and Bevan cellulose but 'pure' cellulose ...

Isolation and Characterization of Holocellulose from Alfalfa

Applied Biochemistry and Microbiology, 2002
Holocellulose isolated from the aerial parts of alfalfa (Medicago sativa) contains a polysaccharide complex of cellulose and hemicelluloses, the major structural components of cell walls. Holocellulose is highly hydrophilic and has a dense biopolymer packing.

Mannose in the holocellulose of Panicum coloratum

Phytochemistry, 1981
Abstract Mannose was observed in addition to other neutral sugars in the holocellulose of Panicum coloratum leaves. It was present in the hydrolyzates of extracted hemicelluloses and was particularly resistant to extraction from the α-cellulose fraction.

Twisting energy of holocellulose fibers

Journal of Polymer Science Part C: Polymer Symposia, 1971
AbstractFreely drying fibers exhibit collapse and twist behavior that is only infrequently observed in the formation of a paper web. Anisotropic fiber shrinkage models are employed that enable calculation of the twisting energy of a freely drying fiber as well as the reverse case (dry to wet).

THE PAPER MAKING PROPERTIES OF STRAW HOLOCELLULOSE

Canadian Journal of Research, 1948
Fibrous holocellulose pulps were prepared in approximately quantitative yield from flax shives and wheat, oat, and fiber flax straw that had been macerated in a buhrstone mill and delignified by sodium chlorite. Paper hand sheets that were formed from pulps subjected to prolonged beating were glassinelike in character.

Holocellulose Determination in Biomass

2012
For determination of holocellulose, the residual yield and its chemical composition during delignification by acidified sodium chlorite have been studied for bamboo (Phyllostachys heterocycla) and Sargassum (Sargassum horneri). It was then found that along with the extended number of chlorination, the residue became yellowish, and then whitish ...

Graft copolymerization of acrylonitrile on thiolated holocellulose

Acta Polymerica, 1988
AbstractGraft copolymerization of acrylonitrile monomer initiated by ceric ions on bleached and thiolated holocellulosic materials was studied. The level and efficiency of grafting on the bleached holocellulose were significantly higher than on the thiolated holocellulose.

Some aspects of graft copolymerization on holocellulose

Die Angewandte Makromolekulare Chemie, 1988
AbstractGraft copolymers of acrylonitrile and methyl methacrylate on unmodified holocellulose and holocellulose containing between 0.3 and 4.6% thiol groups were prepared by the use of Ce4 + initiator in aqueous medium at 29°C. It was found that although the extent of graft polymer formation on the holocellulose was appreciably reduced by the presence ...

Growth and enzyme production by Aspergillus terreus in holocellulose

Annales de l'Institut Pasteur / Microbiologie, 1984
The growth of Aspergillus terreus Thom in holocellulose medium and the production of xylanase and cellulolytic enzymes were studied and compared with growth and enzyme production in xylan and cellulose powder media. Hemicellulose and cellulose were utilized simultaneously by the fungus when grown in holocellulose medium.

THE PREPARATION OF CHLORITE HOLOCELLULOSE

Canadian Journal of Chemistry, 1952
Mildly acid sodium chlorite solutions were allowed to act on white birch and black spruce sawdust at room temperature for various times; the insoluble fraction and the soluble nondialyzable fraction were isolated and weighed. If chlorite acts selectively on lignin the sum of these two fractions in time approaches true holocellulose.
