Advances in microbial delignification

Biotechnology Advances, 1984
Microbial delignification is a new field of applied research. The progress will therefore run parallel to the development of new basic knowledge on the physiological demands of white-rot fungi to degrade lignin and on new knowledge on enzyme mechanisms involved in lignin degradation.

Using cavitation for delignification of wood

Bioresource Technology, 2012
The Kraft process is the most widely used chemical process for the removal of lignin and other polymers from wood to obtain cellulosic pulp fibres. In the present study, the effect of cavitation (growth and violent collapse of vapour bubbles in a liquid) on delignification of wood was investigated.

Selective solvent delignification for fermentation enhancement

Biotechnology and Bioengineering, 1983
AbstractCellulose and hemicellulose in renewable biomass resources such as cornstover and wheat straw have been examined as substrates for the production of ethanol. A mixed culture of selected strains of Clostridium thermocellum and Clostridium thermosaccharolyticum are used to accomplish both the hydrolysis and fermentation of these carbohydrates in ...

The Kinetics of Oxygen Delignification of Reed Kraft Pulp (I)-Kinetics of Delignification

Advanced Materials Research, 2011
The kinetics of reed kraft pulp oxygen delignification process is studied, suitable kinetics model determined is -dk/dt=Aexp(-E/RT) [OH-]b[PO2]cKa, and the parameters in the model is calculated. The function for estimation of the kappa number at different reaction time is established for the reed kraft pulp oxygen delignification process.

Xylanase effects on pulp delignification

Chemical Engineering Communications, 2002
Xylanase effects on softwood pulp delignification were investigated experimentally and using mathematical models. The effect of xylanase molecular size on pulp delignification was investigated. As xylanase molecular weight decreased from 67 kDaltons to 20 kDaltons, lignin removal from pulp increased from 30 wt% to 48 wt%, respectively.

Gas dispersion in the oxygen delignification process

TAPPI Journal, 2021
There has been very little knowledge about the state of gas dispersion in the oxygen delignification process, even though this has a major impact on the performance of the reactor. This paper presents a new continu-ous inline method for measuring oxygen bubble size distribution in the reactor, as well as results from studies con-ducted in softwood and ...
