Hemicelluloses currently represent the largest polysaccharide fraction wasted in most
cellulosic ethanol pilot and demonstration plants around the world. The reasons are based …

Xylan is the principal type of hemicellulose. It is a linear polymer of β-D-xylopyranosyl units
linked by (1–4) glycosidic bonds. In nature, the polysaccharide backbone may be added to 4 …

Abstract Esterases (EC 3.1. 1. x) represent a diverse group of hydrolases catalyzing the
cleavage and formation of ester bonds and are widely distributed in animals, plants and …

The development of new analytical techniques and the commercial availability of new
substrates have led to the purification and characterization of a large number of xylan …

Several plant polysaccharides are partially esterified with acetic acid. One of the roles of this
modification is protection of plant cell walls against invading microorganisms. Acetylation of …

One of natures most important biological processes is the degradation of lignocellulosic
materials to carbon dioxide, water and humic substances. This implies possibilities to use …

Non-cellulosic cell wall polysaccharides constitute approximately one quarter of usable
biomass for human exploitation. In contrast to cellulose, these components are usually …

A metagenome expression library of bulk DNA extracted from the rumen content of a dairy
cow was established in a phage lambda vector and activity‐based screening employed to …

Natural vanillin is of high interest in the flavor market. Microbial routes to vanillin have so far
not been economical as the medium concentrations achieved have been well below 1 gl− 1 …

Carbohydrate esterases (CEs) catalyze the de-O or de-N-acylation by removing the ester
decorations from carbohydrates. CEs are currently classified in 15 families in the …
