Over the past four decades, there has been immense progress in every area of lignin
science, ranging from the enzymology of lignin biodegradation, to the delignification of wood …

The pulp and paper industries are attempting to bring changes to the bleaching process to
minimize the use of chlorine to satisfy regulatory and market demands. Xylanases offer a …

Nonylphenol is a metabolic intermediate from the microbial transformation of detergents
used worldwide. While nonylphenol shows some acute toxicity, it is also able to mimic …

Nuclear magnetic resonance (NMR) can be used to provide an independent and intrinsically
reliable determination of chemical purity. Unlike chromatography, it is possible to employ a …

Two methods are used for the isolation of residual lignin: acidolytic and enzymatic
hydrolysis. Recently a two-step procedure that is a combination of enzymatic and acidic …

TMDP (2–chloro–4, 4, 5, 5–tetramethyl–1, 3, 2–dioxaphospholane) is a very powerful
reagent for tagging hydroxy groups as the 31P-NMR active phosphite derivative (Fig. 1) …

The use of a novel “xylanase A” enzyme was found beneficial in the elemental chlorine free
(ECF) bleaching of oxygen delignified Eucalyptus kraft pulps. The application of the enzyme …

The effects of xylanase on pulp properties and fibre morphology in a TCF (totally chlorine
free) bleaching sequence has been studied. Enzymatic treatment is usually applied after …

Extractability and recovery of cellulose from cell walls influences many industrial processes
and also the utilisation of biomass for energy purposes. The utility of genetic manipulation of …

Mannan and xylan present in bleached softwood dissolving pulp were found to be partially
resistant to hemicellulases even after repeated enzyme treatment. Despite the additional …
