Diversity and dynamics of Archaea in an activated sludge wastewater treatment plant.

ABSTRACT:

Background

The activated sludge process is one of the most widely used methods for treatment of wastewater and the microbial community composition in the sludge is important for the process operation. While the bacterial communities have been characterized in various activated sludge systems little is known about archaeal communities in activated sludge. The diversity and dynamics of the Archaea community in a full-scale activated sludge wastewater treatment plant were investigated by fluorescence in situ hybridization, terminal restriction fragment length polymorphism analysis and cloning and sequencing of 16S rRNA genes.

Results

The Archaea community was dominated by Methanosaeta-like species. During a 15 month period major changes in the community composition were only ob
