Product Description
AU-PE89
Xylanase for Improved Bleaching of Paper Pulps
AU-PE89 Xylanase is an enzyme that degrades xylan. AU-PE89 is specific for xylan and does not degrade cellulose. Xylanases produced by different microorganisms operate optimally over a range of pH and temperature. AU-PE89 was developed from a proprietary strain of bacterium for the paper pulp industry. AU-PE89 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.
TECHNOLOGICAL ADVANTAGE
AU-PE89 acts as a pre-bleaching aid for paper pulps. AU-PE89 has specific advantages in that it is stable and active at the alkaline pH and elevated temperatures typical of kraft pulps.
The main driving factors for acceptance of this technology in pulp mills have been the economic and environmental advantages over chemical bleaching.
AU-PE89 used as a pre-bleaching agent for wood and non-woody pulps can reduce chemical bleach consumption from between 15 to 50%.
APPLICATION
AU-PE89 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 fibre furnish, pulping technology and bleach sequence. The optimal dosage can also depend on the temperature, pH and consistency of the pulp. Application protocols for AU-PE89 can be tailored to best suit the specific process. However, the following general application optimal conditions apply.
Dosage: 135-150g/ T pulp (o. D. Basis)
Pulp properties: PH between 6.5 and9.5
Temperature: Between 45 and 55c
Pulp consistency: Between 6 and 10% (recommended 8%)
Residence time: Above 1 hour
STORAGE
AU-PE89 maintains its stated activity for at least six months when stored at temperatures below 25c. The product maintains its activity for considerably longer when stored at lower temperatures. The product should not be frozen.
HANDLING PRECAUTIONS
AU-PE89 is non-toxic and biodegradable. However, unnecessary contact with the product should be avoided. Long term exposure to protein based products such as AU-PE89 may sensitise certain individuals to the product
