'Engineered Bacterium Produces 1,3-Diaminopropane'
A research team led by Distinguished Professor Sang Yup Lee of the Department of Chemical and Biomolecular Engineering at KAIST reported, for the first time, the production of 1,3-diaminopropane via fermentation of an engineered bacterium.
1,3-Diaminopropane is a three carbon diamine, which has a wide range of industrial applications including epoxy resin and cross-linking agents, as well as precursors for pharmaceuticals, agrochemicals, and organic chemicals. It can also be polymerized with dicarboxylic acids to make polyamides (nylons) for use as engineering plastics, medical materials, and adhesives.
Traditionally, 1,3-diaminopropane is derived from petroleum-based processes. In effort to address critical problems such as the depletion of petroleum and environmental issues inherent to the petroleum-based processes, the research team has developed an Escherichia coli (E. coli) strain capable of producing 1,3-diaminopropane. Using this technology, 1,3-diaminopropane can now be produced from renewable biomass instead of petroleum.
E. coli as found in nature is unable to produce 1,3-diaminopropane. Metabolic engineering, a technology to transform microorganisms into highly efficient microbial cell factories capable of producing chemical compounds of interest, was utilized to engineer the E. coli strain. First, naturally existing metabolic pathways for the biosynthesis of 1,3-diaminopropane were introduced into a virtual cell in silico to determine the most efficient metabolic pathway for the 1,3-diaminopropane production. The metabolic pathway selected was then introduced into an E. coli strain and successfully produced 1,3-diaminopropane for the first time in the world.
The research team applied metabolic engineering additionally, and the production titer of 1,3-diaminopropane increased about 21 fold. The Fed-batch fermentation of the engineered E. coli strain produced 13 grams per liter of 1,3-diaminoproapne. With this technology, 1,3-diaminopropane can be produced using renewable biomass, and it will be the starting point for replacing the current petroleum-based processes with bio-based processes.
Professor Lee said, “Our study suggested a possibility to produce 1,3-diaminopropane based on biorefinery. Further study will be done to increase the titer and productivity of 1,3-diaminopropane.”
This work was published online in Scientific Reports on August 11, 2015.

KAIST Develops Fiber-Like Light-Emitting Diodes for Wearable Displays
Professor Kyung-Cheol Choi and his research team from the School of Electrical Engineering at KAIST have developed fiber-like light-emitting diodes (LEDs), which can be applied in wearable displays. The research findings were published online in the July 14th issue of Advanced Electronic Materials.
Traditional wearable displays were manufactured on a hard substrate, which was later attached to the surface of clothes. This technique had limited applications for wearable displays because they were inflexible and ignored the characteristics of fabric.
To solve this problem, the research team discarded the notion of creating light-emitting diode displays on a plane. Instead, they focused on fibers, a component of fabrics, and developed a fiber-like LED that shared the characteristics of both fabrics and displays.
The essence of this technology, the dip-coating process, is to immerse and extract a three dimensional (3-D) rod (a polyethylene terephthalate fiber) from a solution, which functions like thread. Then, the regular levels of organic materials are formed as layers on the thread.
The dip-coating process allows the layers of organic materials to be easily created on the fibers with a 3-D cylindrical structure, which had been difficult in existing processes such as heat-coating process. By controlling of the withdrawal rate of the fiber, the coating's thickness can also be adjusted to the hundreds of thousandths of a nanometer.
The researchers said that this technology would accelerate the commercialization of fiber-based wearable displays because it offers low-cost mass production using roll-to-roll processing, a technology applied to create electronic devices on a roll of flexible plastics or metal foils.
Professor Choi said, “Our research will become a core technology in developing light emitting diodes on fibers, which are fundamental elements of fabrics. We hope we can lower the barrier of wearable displays entering the market.”
The lead author of the published paper, Seon-Il Kwon, added, “This technology will eventually allow the production of wearable displays to be as easy as making clothes.”
