Zinc-aluminium layered double oxide (Zn-Al-LDO) catalysts derived from layered double hydroxides (LDHs) were prepared and used for the catalytic fast pyrolysis of cellulose to selectively produce 1-hydroxy-3,6dioxabicyclo[3.2.1]octan-2-one (LAC), which is a valuable anhydrosugar derivative. Analytical pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) experiments were performed to invest...

there are many reports on the application of different hydrocolloids in the production of leavened breads; most of which show positive effects on bread quality. however, there is little information to prove such effect on flat breads. the main aim of this study was to improve the quality of barbari dough and bread (iranian flat bread) in terms of texture, taste and general acceptability of fres...

Primary dermal and eye irritation tests of hydrophobically modified hydroxypropyl methylcellulose (HM-HPMC, hydroxypropyl methylcellulose modified with stearylglycidylether), a new cellulose derivative used as a thickener for topical pharmaceuticals and cosmetics, were conducted in rabbits. A dispersion of HM-HPMC (3%) was applied to intact and abraded skins and reactions were observed. A very ...

The high-affinity calcium-mediated type II cohesin-dockerin interaction is responsible for the attachment of the multi-enzyme cellulose-degrading complex, termed the cellulosome, to the cell surface of the thermophilic anaerobe Clostridium thermocellum. A trimodular 40 kDa complex comprising the SdbA type II cohesin and the the CipA type II dockerin-X module modular pair from the cellulosome of...

We describe a new, rapid, and convenient procedure for purifying 2',5'-oligoadenylate synthetases, employing precipitation with ammonium sulfate, fractionation by gel filtration, rapid binding to poly(I) X poly(C) cellulose, and elution with 0.35 M KCl. Unlike previously published methods, the procedure does not require sedimentation of the enzyme at 200,000 X g. Therefore, it is more general a...

Xyloglucan (XG) is the predominant hemicellulose in primary cell wall of superior plants. It has a fundamental role controlling stretching and expansion plant wall. There are five types enzymes known to cleave linear chain xyloglucan, most well-known xyloglucanase (XEG). The immobilization process can be used solve problems related stability, besides economic benefits brought by possibility its...
