T.P. Straatsma is leading a team of researchers modeling the lipopolysaccharide outer membrane of P. aeruginosa to learn how themembrane responds to its environment. This research is addressing the question of how this microbe adsorbs to mineral surfaces and what the mechanism is for the uptake and reduction of heavy metals. This has significant implications for bioremediation applications if these metals are radioactive and are reduced to insoluble form to prevent further spreading of the contamination.
Advances in the molecular modeling and simulation of complex biological systems are enabling researchers to study how certain microbial systems may play an important role in the remediation of contaminated soils. One target is Pseudomonas aeruginosa, a common microbe in sediments and the subsurface. This bacterium is also an important opportunistic pathogen that can cause fatal infections in people with a weakened immune systems.
In another project, the team also is addressing the health related issues concerning this microbe. Again focusing on the outer membrane,Straatsma and his coworkers are studying the role of a range of proteins embedded in the membrane, as well as the mechanism of action of certain antibiotics that are effective in treating P. aeruginosa infections that plaguecystic fibrosis patients, burn victims and patients with compromised immune systems.
