Prof. Lee"s Team Succeeds in Producing Plastics Without Use of Fossil Fuels
A team of scientists led by Prof. Sang-Yup Lee of the Department of Biological Sciences at KAIST have succeeded in producing the polymers used for everyday plastics through bioengineering, rather than through the use of fossil fuel based chemicals, the university authorities said on Tuesday (Nov. 24).
This groundbreaking research, which may now allow for the production of environmentally conscious plastics, has been published in two papers in the journal Biotechnology and Bioengineering.
Polymers are molecules found in everyday life in the form of plastics and rubbers. The team consisted of scientists from KAIST and Korean chemical company LG Chem focused their research on polylactic acid (PLA), a bio-based polymer which holds the key to producing plastics through natural and renewable resources.
"The polyesters and other polymers we use everyday are mostly derived from fossil oils made through the refinery or chemical process," said Lee. "The idea of producing polymers from renewable biomass has attracted much attention due to the increasing concerns of environmental problems and the limited nature of fossil resources. PLA is considered a good alternative to petroleum based plastics as it is both biodegradable and has a low toxicity to humans."
Until now PLA has been produced in a two-step fermentation and chemical process of polymerization, which is both complex and expensive. Now, through the use of a metabolically engineered strain of E.coli, the team has developed a one-stage process which produces polylactic acid and its copolymers through direct fermentation. This makes the renewable production of PLA and lactate-containing copolymers cheaper and more commercially viable.
"By developing a strategy which combines metabolic engineering and enzyme engineering, we"ve developed an efficient bio-based one-step production process for PLA and its copolymers," said Lee. "This means that a developed E. coli strain is now capable of efficiently producing unnatural polymers, through a one-step fermentation process,"
This combined approach of systems-level metabolic engineering and enzyme engineering now allows for the production of polymer and polyester based products through direct microbial fermentation of renewable resources.
"Global warming and other environmental problems are urging us to develop sustainable processes based on renewable resources," concluded Lee. "This new strategy should be generally useful for developing other engineered organisms capable of producing various unnatural polymers by direct fermentation from renewable resources".

Prof. Woo's Team Discovers Eco-Friendly Solid-Oxide Fuel Cell System
A KAIST research team led by Prof. Seong-Ihl Woo of the Department of Chemical & Biomolecular Engineering has found a method to use glycerol, a byproduct from the production of biodiesel, as fuel for solid oxide fuel cells (SOFC), university authorities said on Tuesday (Oct. 27).
The research finding shows that glycerol can be an environmentally sustainable fuel when it is used for operating SOFCs with internal reforming, instead of hydrogen and methane. The finding was published in the Oct. 14, 2009 online edition of ChemSusChem, a sister journal of Angewandte Chemie, the world"s leading chemistry journal.
Biodiesel is an attractive alternative energy source because of its low sulfur content and demand is growing worldwide as oil price soars. Bio-derived glycerol will not contribute to the greenhouse effect and has the potential to contribute to reducing global warming.
Currently, glycereol is used as a raw material in the cosmetic, pharmacy, food, and tobacco industries. However, its supply exceeds its demand as the volume of biodiesel production increases. The production of 1 ton of biodiesel produces 0.1 ton of glycerol. Many researchers have investigated various routes for the consumption of surplus glycerol.
The research is expected to contribute to sustainable growth by reducing the emissions of carbon dioxide and reusing generated carbon dioxide for the production of biomass. The new method enables manufacturers to use glycerol as a fuel for operating SOFC.

Board Chairman Chung Makes First Visit to Building Named After Him
Moon-Soul Chung, chairman of the KAIST board of trustees, visited the building built with his donation on Monday (Oct. 19) for the first time since he made the deed of gift eight years ago, university authorities said on Monday (Oct. 19).
In 2000, Chung, founder and former CEO of Mirae Corp, manufacturer of semiconductor testing equipment, announced retirement and handed over the presidency of his company to one of his managing directors. One year later in 2001, he donated 30 billion won, then equivalent to $30 million, to KAIST. It was by then the largest amount given by a single donor.
The major part of his donation went to constructing a building for the newly-established Department of Bio and Brain Engineering, and it was named after him. However, Chung did not attend the ground-breaking and dedication ceremonies, saying that he would not enter the building until KAIST achieved a breakthrough technology which can inject a hope to Koreans.
On his first visit to the building, he was briefed on the major research outcomes of the department over the past seven years, which were highlighted by the recent invention of an apparatus for measuring perfusion rate of legs. A KAIST team headed by Prof. Chul-Hee Choi invented a light leakage prevention unit including a light emitting device for radiating light having a certain wavelength onto a living body injected with Indocyanine Green (ICG).
According to Prof. Choi, the invention relates to an apparatus for measuring the perfusion rate of legs. The invention also includes a light leakage prevention housing formed to prevent transmission of external light.
Chung expressing satisfaction with the achievements and encouraged professors, researchers and students working at the Moon-Soul Chung Building.
