New insights on the roles of bacteria and protozoa in activated-sludge processes

Wastewater treatment is one of the most important biotechnological processes in the world. Nevertheless, the highly complex microbial communities in wastewater treatment plants (WWTP) are barely understood, remaining, most of the time, as a “black box”. Even though many microbiological methods are available to study the activated-sludge communities, many recent questions on the role of a significant number of m...

Prokaryotic and eukaryotic populations in activated-sludge

Protozoa play a direct role by reducing through grazing the amount of freely-suspended and loosely-attached bacterial cells. Also, filamentous bacteria, although endangering the performance of wastewater treatment plants (WWTP), should be considered as normal components of the activated-sludge microbial community.Correlations between plant performance and the abundance of certain species have been studied, bein...
