Paper Making Xylanase GR-M208

Product Profile

GR-M208 Xylanase is an enzyme that degrades xylan. GR-M208 is specific for xylan and does not degrade cellulose. Xylanases produced by different microorganisms operate optimally over a range of pH and temperature. GR-M208 was developed from a proprietary strain of bacterium for the paper pulp industry. GR-M208 is particularly suited to the elevated temperatures and alkaline pH of kraft pulps.

The manufacturing process involves growing a specific proprietary bacterium in bioreactors (fermenters), separating the cells from the broth, and concentrating the clarified liquid. The product is prepared as a concentrated liquid or light brown powder.

Application

GR-M208 xylanase can be added to pulp after cooking or oxygen delignification and prior to bleaching for the improvement of pulp bleachability. Almost every mill has unique conditions of fiber furnish, pulping technology and bleach sequence. The optimal dosage can also depend on the temperature, pH and consistency of the pulp. Application protocols for GR-M208 can be tailored to best suit the specific process.

However, the following general application optimal conditions apply.

Dosage	40-50g/ T pulp (o.d.basis)
Pulp properties	pH between 6.5 and 9.5
Temperature	between 45 and 55°C
Pulp viscosity	between 6 and 10% (recommended 8%)
Appearance:	light yellow powder or liuqid(Note the color does not affect enzyme activity and effects)
Residence time	above 1 hour

Storage

GR-M208 maintains its stated activity for at least six months when stored at temperatures below 25°C. The product maintains its activity for considerably longer when stored at lower temperatures. The product should not be frozen.
