The quantitative and qualitative fluctuations of benthic microorganisms are indicators of changes in the aquatic ecosystems, especially in sediment reservoirs where microbial diversity is of vital element for the physiological dynamics of such environments. The objective of this project will assess the diversity of benthic microorganisms in the Itupararanga (SP) reservoir through qualitative and quantitative determination of total anaerobic bacteria, reducing bacteria sulfate, denitrifying bacteria and methanogenic archaea. Most probable number (MPN) will be used for quantification of these groups of bacteria and methanogenic archaea, whereas analysis of molecular biology will be used for the identification of such organisms. Therefore, intend to use traditional techniques of microbiology of anaerobes together molecular biology in order to understand the microbial community structure in areas with and without the impact of sewage. That way, it can determine the effect of impact on benthic communities such as allowance for the sustainability of Sorocaba River.
