Studies on Dissolving Bamboo Pulp

application/pdf(1) Dissolving bamboo pulp can be manufactured by application of the processes of "sulphate pulping subsequent to prehydrolysis". When water cooking is applied for prehydrolysis, cooking conditions of 160℃ 4 hrs. and 165℃ 4 hrs. are favorable to produce the dissolving bamboo pulp. In this case, the sulphate cooking condition is the followings; temperature 160℃, time 2 hrs., total NaOH 20% and sulphidity 20%.(2) Pentosan contents in the unbleached pulp depend upon the prehydrolysis conditions, and the pulp which is produced during the above treatments, has less than 5 per cent of pentosan contents. (3) Average degree of polymerization of bleached dissolving bamboo pulp compares favorably with those of dissolving pulp from woods. (4) Chemical properties of dissolving bamboo pulp have no great difference from those of dissolving pulp from woods. (5) There is no a wide difference between the filterabilities of viscose made from bamboo and those from woods. (6) The dissolving bamboo pulp manufactured through these processes, may be possible to be utilized in industrial practice. Bambusa from Indonesia is more suitable than Phyllostachys from Japan for the raw materials of dissolving pulp, in viewpoints of the yield and the average degree of polymerization of pulp.Bulletin of the University of Osaka Prefecture.

Changes in the Amount of Cellular Trehalose, the Activity of Maltooligosyl Trehalose Hydrolase, and the Expression of Its Gene in Response to Salt Stress in the Cyanobacterium Spirulina platensis

The amount of trehalose in cells of the cyanobacterium Spirulina (Arthrospira) platensis increased rapidly when a high concentration of NaCl was added to the culture medium. Inhibition of sodium ion transport by amiloride and monensin significantly decreased the amount of cellular trehalose, suggesting that the influx of sodium ions into the cells is coupled with the accumulation of trehalose. The amount of maltooligosyl trehalose hydrolase (Mth) which produces trehalose from maltooligosyl trehalose increased gradually after the increase in cellular trehalose. The gene for Mth was cloned and identified by Southern blot analysis. Real time RT-PCR analysis revealed that the expression of mth was enhanced by the addition of NaCl to the culture medium. It was concluded that both catalytic activity of Mth and the synthesis of Mth protein were enhanced by the addition of NaCl to the cells.rights: 日本微生物生態学会 rights: 本文データは学協会の許諾に基づきCiNiiから複製したものである relation: IsVersionOf: http://ci.nii.ac.jp/naid/110007131145/textapplication/pdfjournal articl
