Lxxxix. the Hemicelluloses of the Wood of English Oak
PREVIOUS work [O'Dwyer, 1934] has shown that the hemicellulose A of oak wood is a mixed polysaccharide containing anhydroxylose and uronic anhydride units and that the sapwood product differs from that obtained from heartwood in that it gives with iodine the blue colour which is characteristic of starch. It has since been shown [O'Dwyer, 1937] that the blue colour reaction given by the sapwood ...
متن کاملComparison of yeast growth in mesquite wood hydrolysate.
Hot-water extracts of mesquite (Prosopis glandulosa) wood were assayed for their total carbohydrate, reducing sugar, and glucose content. These hydrolysates were then used as complete media for yeast growth. A total of 10 strains of yeasts were evaluated for their biomass production in the mesquite wood hydrolysates. Levels of utilizable carbohydrate proved to be the limiting factor for yeast g...
متن کاملStructures of Hemicelluloses and Pectins in Wood and Pulp
This work aims to fill gaps in the present knowledge of the structures of wood polysaccharides of potential importance in mechanical and chemical pulping. The detailed structures of the polysaccharide components from wood that dissolve during mechanical pulping were determined. The structures of polysaccharide components linked to residual lignin in chemical pulp were also determined. Methylati...
متن کاملSingle-cell protein production in alkaline mesquite wood extracts.
A nine-member, mixed, cellulolytic, bacterial culture was used to evaluate the effects of sodium hydroxide normality, length and temperature of treatment, and the ratio of volume of alkali to mesquite wood on the suitability of alkali mesquite wood extractives as nutrients for bacterial growth. The presence or absence of air during the extraction process did not significantly affect results. Th...
متن کاملHemicelluloses.
Hemicelluloses are polysaccharides in plant cell walls that have beta-(1-->4)-linked backbones with an equatorial configuration. Hemicelluloses include xyloglucans, xylans, mannans and glucomannans, and beta-(1-->3,1-->4)-glucans. These types of hemicelluloses are present in the cell walls of all terrestrial plants, except for beta-(1-->3,1-->4)-glucans, which are restricted to Poales and a few...
