标题 :Method and compositions for improved polynucleotide synthesis
发明人：YANG SHUWEI
权利人:GENECOPOEIA INC
摘要:The sensitivity and specificity of polynucleotide synthesis is increased by protecting the 3'-end of an oligonucleotide used as a primer in the synthesis of the polynucleotide. Protection of the 3'-end of an oligonucleotide prevents non-specific chain elongation. Removal of blocking group an elevated temperature, using a thermostable enzyme, permits template-specific polynucleotide synthesis. The present invention also provides oligonucleotides with a 3' end protected by a blocking group and a thermostable enzyme capable of removing the blocking group at an elevated temperature. The compositions and methods of the invention are very useful in a variety of techniques for DNA/RNA amplification and analysis, including medical genetics research and diagnosis, pathogen detection, forensic, and animal and plant genetics applications, among others.

标题 :Electro-autotrophic synthesis of higher alcohols
发明人：LIAO JAMES C; CHO KWANG MYUNG

摘要:The disclosure provides a process that converts CO 2 to higher alcohols (e.g. isobutanol) using electricity as the energy source. This process stores electricity (e.g. from solar energy, nuclear energy, and the like) in liquid fuels that can be used as high octane number gasoline substitutes. Instead of deriving reducing power from photosynthesis, this process derives reducing power from electrically generated mediators, either H 2 or formate. H 2 can be derived from electrolysis of water. Formate can be generated by electrochemical reduction of CO 2 . After delivering the reducing power in the cell, formate becomes CO 2 and recycles back. Therefore, the biological CO 2 fixation process can occur in the dark.

摘要:Disclosed are recombinant yeast strains and a use thereof in the production of a benzylisoquinoline alkaloid. The recombinant yeast strains comprise berberine bridge enzyme. De novo synthesis of scoulerine and a benzylisoquinoline alkaloid is achieved through multiple strategies, and the yield thereof is significantly increased. The recombinant yeast strains provided by the present invention can produce scoulerine and other benzylisoquinoline alkaloids at high efficiency, and has important value in applications.

标 题 :Synthesis method of polycarboxylic acid water-reducing agent
发明人：FANG JIAN
权利人:FANG JIAN; SHANGHAI TAIJIE CHEMICAL CO LTD
摘要:A method for synthesizing concrete polycarboxylic acid water-reducing agent at room temperature under non-stirring situation is disclosed, which comprises dissolving reactive materials, initiator, chain transfer agent and promoter into a solvent, reacting on standing at 0-50° C.; then adding neutralizing agent at the end of reaction. The method makes use of oxidation-reduction system reacting at low temperature, and can adapt to a variety of reactive material monomers. It does not need to control feeding speed or provide extra heating, does not need to stir during the reaction, and remarkably simplifies operation steps in traditional process, which makes it possible to not only produce in large scale, but also produce in small scale in concrete construction site at any moment.
