Ask Assistant Professor of Chemical Engineering Camilla Kao to describe a bacterium, and shell compare it to a factory capable of producing antibiotics, immunosuppressants and anti-cancer drugs that no chemist can synthesize. Bacteria normally produce antibiotics to inhibit other bacterial strains competing for resources. Pharmaceutical companies exploit this property to manufacture drugs, but the process of cultivating bacteria is slow and costly. By hijacking molecular synthesis with the latest advances in biotechnology--and inducing bacteria to overproduce antibiotics--Kao aims to greatly speed up drug development.
"Companies have proprietary mutant [bacterial] strains that have been worked on for more than 20 years, but many of the mutations still are unknown," Kao said. "Theres no knowledge you can gain from these overproducers to turn around and make others."
Thats where Kao comes in. On Sunday, she will present her latest progress at the 229th annual meeting of the American Chemical Society in San Diego, focusing on research that earned her the 2004 Jay Bailey Young Investigator Award, which recognizes the best paper in the journal Metabolic Engineering.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
