DNA modified papermaking materials

Zencea of ​​the United Kingdom cooperated with Nippon Paper Co. of Japan to carry out research and use genetic recombination technology to control the lignin biosynthesis system during the growth of trees. Zencea has isolated a gene inhibitor of cinnamyl-alcohol dehydrogenase that inhibits the growth of lignin in trees. This particular gene enzyme has been implanted in the fast-growing poplar and eucalyptus varieties that they developed to cultivate new ones. A generation of pulp and paper. The wood is easy to dissolve out during the cooking process, which can save the amount of chemicals and energy consumption, reduce the damage and degradation of the fibers, thereby improving the pulp yield and quality, saving fiber raw materials, reducing the pollution load of wastewater and reducing the cost of wastewater treatment Wait.
