Purdue University School of Chemical Engineering - Graduate Seminar Series

Purdue University School of Chemical Engineering Graduate Seminar Series Dr. John A. Morgan Associate Professor, School of Chemical Engineering Purdue University "Determination of Metabolic Fluxes in Green Organisms" November 23, 2010 3:30 - 4:30 p.m. FRNY G140 Abstract: Photosynthetic microorganisms are of prime importance in the global carbon cycle, the current source of nutrients and a promising source of biofuels. A major thrust of our research is a systems level understanding of metabolism that will enable the rational manipulation of metabolic networks in photosynthetic organisms. Evaluation of the rates and yields of metabolic pathways under different environmental and genetic conditions provides the basis for effective metabolic engineering strategies. To accomplish this goal, a key tool is the measurement of metabolic rates also as known as metabolic fluxes. We have been a leading group developing the mathematical models and measurement techniques resulting in the first metabolic flux maps for cyanobacteria (blue-green algae) and microalgae. Significant progress will be reported on the formulation of stoichiometric models of photosynthetic microbes including details of light harvesting. Constraint based models were constructed and tested for the cyanobacteria Synechocystis PCC6803, and a genome scale model for the photosynthetic algae, Chlamydomonas reinhardtii. Predictions of metabolic fluxes were calculated by specifying an objective function, such as maximizing biomass synthesis, and performing linear programming to determine optimal fluxes satisfying stoichiometric constraints. We will present our findings for predicted metabolic flux distributions under hetero-, mixo-, and autotrophic growth conditions. Experimental validation by 13C metabolic flux analysis will be detailed for the two model organisms and the results compared with the predictions. Each of these studies demonstrates the powerful insight that mathematical analysis provides on systems of complex reaction networks. Bio: John Morgan received a B.S. and M.S. in Chemical Engineering from University of Kansas and a Ph.D. from Rice University in Chemical Engineering. He then completed postdoctoral studies with Professor Douglas Clark at the University of California, Berkeley. John began his academic career as an assistant professor in the School of Chemical Engineering at Purdue University in 2000, and was promoted to Associate Professor in 2006. His research focuses on metabolic engineering of plants and microbes, with a particular focus on photosynthetic organisms. Advances in the techniques of metabolic flux analysis are integral to Prof. Morgan's research efforts. Debbie Luedtke Deborah P.

Server downtime 11/22, missing notebook, and slight 'change' to mail 'alias' lists.
by Harrington, Michael P 19 Nov '10

19 Nov '10

Hi everyone, Three quick notes. First the machine room in Civil that houses several ChE servers will have the A/C system maintenance performed on Tuesday 11/22 from 6:30 to 8:30am. While Atom and the print server VPS4 will remain on, the following servers will be down during that time: catalyst, faucet, tipstream, gibbs0, gibbs1, gibbs2, mx05, ion and molecule. Also I believe I misplaced my notebook (a blue 'steno' pad) last Thursday. I don't think my name is on it anywhere however it does mostly have things written down that are computer related such as computer names, programs, etc. If you have found it or happen to see it sitting in your area please let me know and I will come pick it up! Lastly this past week I made a slight change to the way the 'mail alias' lists works and all mail sent to chme, chefaculty, chmegrad, etc now goes through ECN's 'mailman' server which means it goes through an additional level of spam processing. Hopefully some of you have noticed a bit less 'spam' showing up in your inbox. Now only people sending mail from a purdue.edu or a @gmail.com address (the most popular non @purdue address people use) will have their mail sent on automatically when sending mail to the mail alias addresses, all others will be delayed. If you have a email account that is not a purdue.edu (including ecn.purdue.edu) or gmail.com address and you wish to send mail to any of the mail alias lists please sent a note to cheq(a)ecn.purdue.edu and request that the address be added to the 'white list' so messages won't be held for moderation. Thanks and have a great Thanksgiving! Mike ******************** Mike Harrington Computer Facilities Manager Chemical Engineering Purdue University 765-494-6428 mph(a)purdue.edu
