BACKGROUND Ultrafine grinding is an environmentally friendly pretreatment that can alter the degree of polymerization, the porosity and the specific surface area of lignocellulosic biomass and can, thus, enhance cellulose hydrolysis. Enzyme adsorption onto the substrate is a prerequisite for the enzymatic hydrolysis process. Therefore, it is necessary to investigate the enzyme adsorption proper...

Rice straw is a very abundant lignocellulose agricultural waste in Indonesia. This generally used as much 31% for animal feed, 7% industrial purposes, and 62% burned rice fields. burning can cause respiratory disorders such ARI cancer. Lignocellulose itself polysaccharide consisting of lignin, cellulose, hemicellulose. The lignin content be the production edible film, so to increase its usefuln...

Abstract Herein, two new polymers designated as Cs-EATT and Cs-BATT have been synthesized via linking the chitosan with 1,3,4-thiadiazole compounds. They were characterized using 1 H, 13 C-NMR, FT-IR, TGA, Elemental analysis, Mass spectrum, UV–vis spectrophotometer. The exhibit high activity to control growth of pathogenic bacteria ( S. aureus , B. subtilis E. coli, P. aeruginosa ), unicellular...

The Ektachem story starts in 1970 at the Eastman Kodak Co. in Rochester, NY. For some time, Eastman Organic Chemicals had supplied reagents to the clinical laboratory. Al Baitsholts, product manager for a thin-layer chromatographic system of impressive analyte sensitivity, became convinced that some kind of thin-layer format might form the basis for a new approach to routine clinical chemistry ...
