Kinetic method for the study of xylan hydrolysis by xylan hydrolases

Monatshefte f�r Chemie Chemical Monthly, 1989
The Somogyi-Nelson colorimetric method was used in a new manner more suitable for evaluating the kinetics of the enzyme hydrolysis of xylan catalyzed by xylan hydrolases. The values of the Michaelis parameters (Km=5.56 g l−1 andV=2.94 · 10−5M s−1) were determined.

Modular synthesis of non-charged and ionic xylan carbamate derivatives from xylan carbonates

Carbohydrate Polymers, 2019
Novel non-charged and ionic xylan carbamate (XC) derivatives were synthesized in a modular approach from xylan phenyl carbonates (XPC) as reactive intermediates. XPC with varying degrees of substitution (DS) from 0.5 to 1.9 were converted with different non-ionic primary and secondary amines in different molar ratio to obtain the corresponding XC with ...

Xylan spectroscopy and spectrophotometry

Biotechnology Techniques, 1990
An iodine-iodide reagent containing saturated calcium chloride was used for quantitation of larchwood xylan in solution and for improved visualization of xylanase activity on solid media. This spectroscopic methodology is applicable to hemicelluloses from other sources and can differentiate hemicelluloses from other polysaccharides such as amylose ...

Xylan and Xylan Derivatives – Basis of Functional Polymers for the Future

2011
This review highlights xylan and xylan derivatives. It depicts the occurrence and structural diversity of the biopolymer, followed by a presentation of different ways of isolation from biomass. The determination of characteristics, i.e., molecular weight, interaction with other polysaccharides, thermal behaviour, and the biological activity of xylan ...
