标题 :Modification of lignin synthesis in plants
发明人：BOUDET ALAIN MICHEL; INZE DIRK GUSTAAF; SCHUCH WOLFGANG WALTER
权利人:ZENECA LTD
摘要:The synthesis of lignin by plants is controlled by transformation of the plant genome with a recombinant gene construct which contains the gene specifying an enzyme critical to the synthesis of a lignin precursor, which gene may be in antisense orientation so that it is transcribed to mRNA having a sequence complementary to the equivalent mRNA transcribed from the endogenous gene thus leading to suppression of lignin synthesis. If the recombinant gene has the lignin enzyme gene in normal, or 'sense' orientation, increased production of the enzyme may occur when the insert is the full length DNA but suppression may occur it only a partial sequence is employed.

标 题 :New preparation process of resole resin with activated kraft lignin
发明人：Žibret Nina; BUKOVEC PETER; Žibret Slavko; VERDEL NADA

摘要:The subject of the invention is a novel process for the preparation of resole resin with activated Kraft lignin, wherein the lignin activation reaction is carried out in a first step and the synthesis of a new lignin-containing resole resin is carried out in a second step, all in the same reactor. A proportion of phenol is replaced by lignin, thus reducing the use of phenol as a feedstock, and the resole resin synthesised has a low molar mass and lower tetradimer values than existing resole resins used as binders in the manufacture of thermally insulating glass wool and rock wool. The new process for the preparation of resole resin with activated Kraft lignin increases the resin's unlimited solubility and stability up to 30 days. When using the resole resin according to the present invention as a binder for a thermal insulation panel, lower formaldehyde and phenol emissions are demonstrated.

标题:Eco-friendly process for the isolation of biopolymers from agricultural residues

摘要:Agricultural residues (biomasses) have come-up as potential valuable renewable resources for transformation into many bio-products. To achieve this goal, the isolation of major biopolymers in their purest form through an economical process is demanded for synthesis of the target fine chemicals without impurities. However, the difficulty of fractionating the biomass into cellulose, hemicellulose and lignin by a simple method has greatly limited their isolation from agricultural residues. Also, the lipids and waxes present on the surface of the agricultural residues protect it from external chemical and microbial agents. To overcome this issue, the lipids and waxes have been isolated from the biomass through two step organic solvents extraction. Thereafter lignin, hemicellulose and cellulose are isolated successively from the de-waxed biomass.
