in this research, the characteristics of cmp dioxane lignin (hardwood origin) and soda bagasse lignin (ethanol soluble fraction) and dioxane lignin of bagasse were studied using gel permeation chromatography, gas chromatography-mass spectrometry and 13c nmr spectroscopy and dfrc degradation procedure. the results indicated that the main structural units in lignins are phenyl propane skeletons b...
The extracellular endo-1,4-beta-glucanase components of Ruminococcus flavefaciens FD-1 were analyzed by high-performance liquid chromatography (HPLC) by using DEAE ion-exchange, hydroxylapatite, and gel filtration chromatography and polyacrylamide gel electrophoresis (PAGE). Two endo-1,4-beta-glucanase peaks were resolved by DEAE-HPLC and termed endoglucanases A and B. Carboxymethyl cellulose (...
