摘要： The present invention relates to an improved process for producing chemical cellulose pulp wherein biopolymers are added immediately before, during or after a bleaching step, depending on pulp characteristics and on process conditions used. The biopolymers according to the present invention are starch by an etherification reaction. This treatment results in a differentiated pulp having improved physical, chemical and mechanical properties when compared with cellulose pulps obtained by traditional processes. The use of said biopolymer alters the relations between important pulp properties rendering their application in papermaking process advantageous. This differentiation increases the possibilities of use and also of new applications, including for the substitution of pulps produced from other cellulose sources. Thus, the present invention also relates to a process for the preparation of paper, such as printing, writing, decorative, special or tissue-type papers, through the use of the cellulose pulps modified by the above process.

摘要： Polynucleotide, DNA constructs and methods are disclosed for the modification of cellulose content in plant tissues. Plants are transformed with constructs encoding either an active Anabaena sp. sucrose synthase gene or a soybean nodule sucrose synthase gene, which leads to increased cellulose content when over-expressed under the control of a cambium/xylem preferred promoter. Plant transformants harboring an Anabaena sp. or a soybean nodule sucrose synthase gene demonstrated increased content of cellulose, a trait that is thought to improve woody trees for cellulose extraction during pulping and papermaking.
