摘要: AbstractEnhanced biological phosphorous removal (EBPR) from wastewater has been successfully used for more than three decades and is considered to be an environmentally friendly wastewater-treatment process. Biologically, this process realized by incorporation of phosphate as polyphosphate (polyP) granules in activated sludge bacteria. Important groups bacteria responsible P have identified, but the full microbial diversity involved still unknown. This paper reports on composition communities eight plants (WWTPs) with different sizes modes operation. The accumulating organisms (PAOs) within complex biocenosis were identified fluorescent dye staining classified situ hybridization techniques. Of aerobic basin, 5–13% contained polyP granules. In addition, flow cytometry was quantify PAOs after tetracycline separate these cells. ...
