Innovative Bioreactors for Contaminated Air and Water Treatment: From Nano to Field Demonstration

Lyman Handy Colloquium SeriesPresentsMarc A. DeshussesDepartment of Chemical and Environmental Engineering, University of California RiversideAbstractBiological systems have a fantastic potential for the biotransformation of a wide range of substances including treatment of numerous man made pollutants. This provides opportunities for the development of novel and environmentally friendly bioprocesses for pollution control. In this seminar, recent research in the area of bioreactors for air and groundwater pollution control conducted in Deshusses' group will presented and discussed. This will includes the simple synthesis of reactive nanomaterials for environmental application, the use of molecular methods and establishment of relationships between pollutant removal and DNA or RNA fingerprints, high performance biotrickling filters treating H2S at a gas contact time as low as 1.5 seconds, and the treatment of perchlorate contaminated groundwater by bacteria deriving energy from iron particles on which they are attached. The discussion will include lab and field data and a brief assessment of the sustainability of some of these novel developments. BiographyDr. Deshusses' broad research interests are related to the design, analysis and application of systems for bioremediation of wastes in air, water and soils. One area of on-going research is air pollution control in gas-phase bioreactors. Results from this work have resulted among others in a better fundamental understanding of how VOCs and odors are biodegraded in biofilters and biotrickling filters. The research has also shown how to convert odor control chemical scrubbers to high-efficiency biotrickling filters at wastewater treatment plants. Other areas of research include bioremediation of groundwater contaminated with the gasoline additives (MTBE and TBA) or with perchlorate, the development of gas phase nanosensors, and reactive nanomaterials for environmental applications. Other research interests include biofilms, application of molecular tools for monitoring complex cultures, combined chemical and biological treatment of wastes, membrane bioreactors, and modeling of environmental bioprocesses.http://www.engr.ucr.edu/~mdeshuss/

Translocon-Assisted Folding of Membrane Proteins: New insights into Lipid-Protein Interactions
Thu, Mar 27, 2008 @ 12:45 PM

Mork Family Department of Chemical Engineering and Materials Science Distinguished Lecture SeriespresentsProfessor Stephen H. White,
Dept. of Physiology and Biophysics,
University of California at Irvine, Irvine, CA 92697AbstractRecent studies of the translocon-assisted folding of membrane proteins have revealed two unexpected findings about the insertion of transmembrane helices across the endoplasmic reticulum membrane. First, the so-called S4 voltage-sensor helix of potassium channels, comprised of hydrophobic residues and four arginine residues, can be inserted. Second, polyleucine helices as short as 10 residues are readily inserted. Exploration of these observations using physical studies of synthetic peptides in model membranes and molecular dynamics simulations provide new insights into lipid-protein interactions. They reveal that the lipid bilayer is far more complexand interestingthan its usual lollypop cartoon suggests. The biological, physical, and molecular dynamics data to be presented demonstrate the extreme adaptability of phospholipids that arises from the privileged relationship between their phosphate groups and lysine and arginine residues. This adaptability makes possible the transmembrane insertion of very short helices and the independent stability of potassium channel voltage-sensor domains in membranes.
