Book excerpt: Both municipal engineering and environmental engineering are disciplines aimed at promoting human welfare. The former focuses on establishing life-supporting public infrastructure, while the latter emphasizes treatment and restoration of polluted environment. Typically, the engineers deal with various contaminants (e.g., nutrients, heavy metals and organic contaminants) existing in different environmental media (e.g., soils, water sources, sewage and solid wastes). So far, plenty of technologies and engineering systems have been developed in which microorganisms play important parts. In some cases, microorganisms play a leading role, as their metabolism influences the degradation and transformation of the contaminants. In other cases, as a part of the target environments, microbial communities are forced to change, which reflects the performance of the applied technologies/systems or their impacts on the health of ecosystems and living organisms.
