KAIST, GS Caltex Jointly Develop New Bacteria to Produce Biobutanol
KAIST and GS Caltex, Korea"s second-largest refiner, have jointly developed a new strain of bacteria to produce biobutanol, which is regarded as a promising next-generation biofuel, KAIST authorities said on Monday (June 2). A research team led by Prof. Sang-Yup Lee of the Chemical and Biomolecular Engineering Department and researchers of GS Caltex succeeded in developing an improved strain of bacteria which enables to produce a large amount of biobutanol in the process of fermenting biomass. The research team has applied for international patent for the new technology. Biomass refers to living and recently dead biological material that can be used as fuel or for industrial production. It usually refers to plant matter grown for use as biofuel, but it also includes plant or animal matter used for production of fibers, chemicals or heat. In the 1970s and 1980s when scientists began researching the possibilities of alternative fuels, bacteria were used in the process of fermenting biomass. This ABE (acetone, butanol, ethanol) fermentation process yields butanol, acetone, and ethanol in a ratio of 6:3:1, respectively. Acetone produced in this process is not usable. The newly developed technology to produce biobutanol has an advantage of lowering production cost by eliminating the process to separate acetone from butanol. This has been made possible by improving the bacteria used for the fermentation in metabolic engineering terms, and producing butanol and ethanol only in a ratio of 6:1, while curbing the generation of acetone. In comparison with bioethanol, also a biofuel mixture which is currently under widespread use in some countries, butanol is more easily transported with gasoline and diesel through pipelines because of its lower tendency to separate from the fuel when contaminated with water. Butanol is also less corrosive than ethanol, another reason its transport through pipeline is preferable. Global interest in full utilization of biomass and development of other alternative energy including biobutanol has deepened in recent years, as crude oil prices have skyrocketed to record levels and climate changes resulting from the excessive use of fossil fuel have been causing various problems around the world.

President Suh and Vice President Soon-Heung Chang presented degrees to each of the 1,321 graduates (200 doctors, 725 masters and 396 bachelors) instead of just to representatives. Since its inception in 1971, KAIST has produced 7,067 Ph.D. graduates, 18,636 master"s degree holders and 8,998 bachelor"s degree holders. This year, 40 percent of the Ph.D. graduates, 79, were in their twenties upon graduation. President Suh called on the graduates to return the favor they received from society by making their share of contributions to humanity. "You were chosen to be students of this unique university because the Korean people -- not only KAIST professors and staff, but also ordinary taxpayers -- believe that outstanding young people like you can change the world in which we live for the better. Now it is time for you to pay back their support," he said. Notable graduates of this year include So-Yeon Yi, 29, the first Korean female astronaut candidate, who earned her doctorate degree in bio and brain engineering. She was granted a special award in recognition of her role in advancing space science in Korea but she could not attend the graduation ceremony due to her training schedule in Russia which will continue until April. Eun-Gyu Oh, 26, was the youngest doctorate recipient in the ceremony and Won Hye-jeong, 21, recorded the top undergraduate GPA with a score of 4.20 over 4.3. Civil and environmental engineering major Seung-Hee Park, 28, published a total of eight papers in major international journals while attending KAIST and two more papers are currently under review. So-Yeon Yi said: ``I frequently stayed up all night to research and write the paper. It was tough experience for me. Thanks to ceaseless support from professors and colleagues, however, I was able to complete the task,"" she said. ``I have done my best in studying, exercising and so on. I"m sure that my active, participatory attitude brought about this honorable moment."" She is now training at Gagarin Cosmonaut Training Center near Moscow as a replacement astronaut in case Koh San, 31, who is to be the first Korean astronaut, is unable to go into orbit.

KAIST Students Wins Gold Prize at Technical Idea Contest
KAIST Students Wins Gold Prize at Technical Idea Contest - Receive the gold prize at the 3rd High-Tech Daejeon Technical Idea Contest for Company Establishment- For the development of a new system to convert complex web page addresses to short and meaningful addresses Sang-Hoon Kim, Song-Hwa Chae and Dong-Hun Lee of Chemical and Biomolecular Engineering won the gold prize at the prospective company establishment part in the 3rd High-Tech Daejeon Technical Idea Contest for Company Establishment on May 21 for their valuable development of ‘Web Page Address Clipping System’. So far, simplified web page addresses include special characters, which make the addresses long and complex. That is, the current address simplification service combines meaningless random words and numerals to create addresses when web page addresses are entered. In this case, the addresses are not easy to share with others and reuse several times since they are difficult to memorize. However, the ‘Web Page Address Clipping System’ shortens meaningless long addresses. In addition, the improved address simplification service will provide user’s own addresses, and statistics and ranking to clipping addresses frequently used. Based on this technology, Kim and Chae are now preparing to open a company called ‘URLClip’ under the auspice of Professor Tae-Yong Yang and Researcher In-Soo Kim, KAIST Entrepreneurship Center. They are also expanding their service areas onto clipping library for individual users, host name services for enterprises, etc. and developing tool bar, RSS service (RSS is an acronym of RDF (or Rich) Site Summary. It refers to a service that automatically and easily provides frequently updated contents such as news and blogs to users), etc. to improve users’ conveniences. URLClip (http://www.urlclip.net) is a next generation portal site, which is expected to provide a variety of individualized services based on Web Page Address Clipping Service and to be used by many enterprises as well as individual users who wish to enhance their access to useful contents. “Chemical & Biomolecular Engineering Professor Sun-Won Park has offered lots of helps and supports, so I could decide to commercialize the developed technologies. The application of this technology to real life will allow further comfortable uses of internet to users,” Kim said. Narae Team received the best prize last April at the 2nd Pre-Star Venture Company-Opening Contest hosted by KAIST and Hanbat Univeristy, and the technology is pending a patent application.

Maximum Yield Amino Acid-Producing Microorganism Developed with use of System Biotechnology A team led by Sang-Yup Lee, a distinguished professor of Chemical and Biomolecular Engineering and chair professor of LG Chemical, has succeeded in developing maximum yield L-valine-producing microorganism by using System Biotechnology methods. The research results will be published at the April fourth week (April 23 - 27) edition of the Proceedings of the National Academy of Sciences (PNAS) of the USA. Prof. Lee’s team has developed maximum yield amino acid-producing microorganism (target substance of L-valine, an essential amino-acid) by using microorganism E cell system and simulation methods. His team produced initial producing microorganism by selectively operating necessary parts in colon bacillus genome and excavated preliminary target gene which is to newly be operated through transcriptome analysis using DNA chips. Then they performed a great amount of gene deletion experiment on computer by using MBEL979, E-cells of colon bacillus, and excavated secondary engineering targets. And they finally succeeded in developing maximum yield valine-producing microorganism that can extract 37.8 grams of valine from 100 grams of glucose by applying experiment results to the actual development of microorganism so as to achieve the optimization of metabolic flux in cells, Prof. Lee said, “Since successfully used for the development of microorganism on a systematic system level, system biotechnology methods are expected to significantly contribute to the development of all biotechnology-relevant industries. At the beginning, we had huge obstacles in fusing IT and BT, but my team mates cleverly overcame such obstacles, hence I’m very proud of them.” The producing microorganism and its developing methods are pending international applications (PCT).

The both recently reached an accord on the implementation of DDP and will exchange maximum five students each year, starting this year. The DDP allows each school involved to exchange students who meet the counterpart’s requirements one-by-one with prior consensus of departments to accept the students and to confer its own diplomas on students who complete the prescribed graduation requirements. TU Berlin, established in 1770, currently holds 28,344 enrolled students, among which 5,829 students are from abroad (over 20%) and provides lectures for more than 50 subjects in the fields of Humanities, Social Sciences, Economics and so on with its emphases on Natural Science and Engineering. TU Berlin has fostered a multitude of distinguished scientists, including 1986 Nobel Prize Recipient in Physics Ernst Ruska who developed an electronic microscope for the first time in the world. KAIST has now been eagerly promoting the DDPs with many distinguished foreign universities. It is on the final stage of the DDP negotiation with Georgia Institute of Technology (GIT) and University of California Santa Barbara (UCSB), and has already agreed with Tsinghua University in China to implement the DDPs in several advanced fields. Also, an agreement with Tokyo Institute of Technology (TIT) is soon to be made. With Ecole Polytechnique and INSA Lyon of France, and University of Karlsruhe of Germany, the negotiation is underway at department levels, and the DDPs are also being promoted with Milan Technical University of Italy, Delft University of Technology of Netherlands, Royal Institute of Technology (KTH) of Sweden, Technical University of Denmark (DTU), Norwegian University of Science and Technology (NUNT). “As global interests in East Asia arise, interests in KAIST by many foreign universities also increase. We are planning to expand the scope of this program to provide KAIST students with more opportunities of studying abroad and to attract more outstanding foreign students,” KAIST Dean of Academic Affairs Kwang-Hyung Lee explained. - Dual Degree Program (DDP)In DDP, schools involved can maintain their own curriculums and confer their own degrees on students who complete the graduation requirements. Therefore, students can receive degrees from both schools involved. Meanwhile, DDP is not the same concept with Joint Degree Program (JDP), in which schools involved establish a joint curriculum and confer a single joint degree on students.
