Cellulose Chemistry and Technology
The application of the microencapsulation technique in medicine and pharmacy has been extensively studied in recent years. The microencapsulation of small particles in polymeric, waxy or other kind of protective shells has become a well-established technology for coating and isolating various substances. The present paper presents the results obtained in a study concerning the influence of cros...

Out of 12 fungal strains, two fungal strains, namely Aspergillus flavus AT-2 and Aspergillus niger AT-3, were found to produce maximum cellulase production. The CMCase activities of A. flavus AT-2 and A. niger AT-3 under state solid fermentation (SSF) conditions were of 42.69 and 40.08%, respectively, which was higher than those obtained under submerged fermentation (SmF) conditions. A fungal i...

Concentrations of cellulose, lignin and nutrients in the stemwood of four clones of 7-year-old hybrid aspen (Populus tremula L. x P. tremuloides Michx.) were studied on 50 permanent experimental plots established for the afforestation of abandoned agricultural lands in Estonia. Quantitative evaluation of hybrid aspen chemical components indicated a relatively high cellulose and low acid-insolub...

The objective of this project is to develop a process for the parallel production of ethanol and cellulose in a pulp mill, by applying a prehydrolysis step to softwood chips to extract hexose sugars for their subsequent fermentation in ethanol. Two kinds of pretreatments were compared, an acid hydrolysis and a two-step treatment composed of an autohydrolysis and a post-hydrolysis of the resulti...

-1,4-Glucans having oligosaccharide appendages (O-/N-linked -maltoside and O-/N-linked -lactoside) at 6C positions of all repeating units can be readily prepared from cellulose through a two step strategy composed of: (1) regio-selective and quantitative bromination/azidation to afford 6-azido-6-deoxycellulose; and (2) the subsequent Cu + -catalyzed coupling with oligosaccharides having term...
