摘要: Improved pulp strength and brightness of chemically produced pulp can be obtained by treating the pulp with the addition of 0.05-0.5% based on the weight of the dry fiber of certain amine materials in the hypochlorite bleaching stage....
LACCASEBACILLUS (Bacteria)BACILLUS licheniformisRICE branHOT springsBIOSURFACTANTSThe continuous requirement for pre-bleaching processes on kraft pulp, employing a range of compatible enzymes, aims to mitigate the pollution caused by chemical bleaching agents. In the present study, the laccase-p...
Pulp and paper mills can do much in this respect; they represent almost 50% of the energy consumption in Swedish industry. In kraft pulp mills, the greatest energy demand is usually in the evaporation plant. To simulate the plants, an existing tool was developed and used; important parameters...
The effects of 1-hydroxybenzotriazole (HBT) and the natural laccase mediators gallic acid, caffeic acid and p-hydroxybenzoic acid, on the enzymatic bleaching of flax pulp were compared. The treatment was performed under atmospheric air and oxygen pressure, and, for the first time, monitored by ...
The essential feature of the\ninvention is that the pulp is treated, either in conjuction\nwith or before oxidation, with a lignin-modifying oxidation-\nreduction enzyme, such as the laccase produced by the white-\nrot fungus. The oxidating bleaching chemical used in the\nprocedure may be ...
In addition, laccases have also found multiple roles in biotechnological industries, such as in bioremediation of phenolic pollutants, textile industry, food industry, and paper and pulp industry. This chapter discusses the activity of laccase on LCB and its classification. Also, the different ...

Each laccase鈥搈ediator treatment was used in the following TCF bleaching sequence: LQPo (Q denoting a chelating stage and Po a pressurized alkaline peroxide treatment). Also, a xylanase pretreatment was carried out for first time here to assess its effect on flax fibre. Pulp (kappa number, ...
