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 sudden influx of new chemical pollutants entering the plant. Such perturbations elicit stress responses from the microbial community, which may interfere with the treatment plant functions. This talk will investigate the effect of these stress responses on the metabolism of a microbiological population of Pseudomonas aeruginosa. We find that activation of the stress responses diverts carbon and energy resources away from growth, leading to a decrease in biomass yields. However, multiple exposures to the chemical pollutants may lead to development of resilience in the population, mitigating to some extent the harmful effects of the pollutants.
