DESCRIPTION:Microorganisms are responsible for breaking down organic waste
  in municipal and industrial sewage in treatment plants so that it can be 
 safely disposed of. However\, these organisms may be perturbed by the sudd
 en influx of new chemical pollutants entering the plant. Such perturbation
 s elicit stress responses from the microbial community\, which may interfe
 re with the treatment plant functions. This talk will investigate the effe
 ct of these stress responses on the metabolism of a microbiological popula
 tion of Pseudomonas aeruginosa. We find that activation of the stress resp
 onses diverts carbon and energy resources away from growth\, leading to a 
 decrease in biomass yields. However\, multiple exposures to the chemical p
 ollutants may lead to development of resilience in the population\, mitiga
 ting to some extent the harmful effects of the pollutants.\n
