The Effects Of Ph On Enhanced Biological Phosphorus Removal (ebpr) With Propionic Acid As The Dominant Volatile Fatty Acid (vfa)
… thereby creating conditions where phosphorus-accumulating organisms (PAOs) are able to take up acetate faster than glycogen-accumulating organisms (GAOs). They explained this observation by comparing the growth rate of phosphorus-accumulating organisms (PAOs) and glycogen-accumulating …

The effects of acetate concentrations on competition between microbial populations in enhanced biological phosphorus removal from wastewater
… the bacteria responsible for EBPR, polyphosphate accumulating organisms (PAOs), have an advantage over their competitors, the glycogen accumulating organisms (GAOs). Because research EBPR systems have been primarily sequencing batch reactors (SBRs), which include rapid feed addition and relatively …

Metagenomic characterization of Candidatatus Defluviicoccus tetraformis TFO71, a tetrad-forming organism, predominant in an anaerobic-aerobic membrane bioreactor with deteriorated biological phosphorus removal
… (EBPR), Defluviicoccus-related tetrad-forming organisms (DTFO) were observed to predominate in the microbial community. Using metagenomics, a partial genome of the predominant DTFO, “Candidatus Defluviicoccus tetraformis TFO71,” was successfully constructed and characterized. Examining the …

Bioplastics from C1 Gases - Substitute Sustainable Products for Polymer Coated Steel
… into acetate. It was then proposed to use glycogen-accumulating organisms (GAOs), which are bacteria obtained from wastewater treatment plants, to produce mixes of biopolymers called polyhydroxyalkanoates (PHA). With acetate as the sole carbon source and by varying several culture …

Evaluation of Glycerol and Waste Alcohol as Supplemental Carbon Sources for Denitrification
… generalist population of ordinary heterotrophic organisms (OHO) that use substrate, glycerol in this case, less efficiently, producing low yields and slow growth rates, to a specialist population that use glycerol more efficiently, with higher yields and slightly faster growth rates, was …

METABOLIC SHIFT AND NICHE DIFFERENTIATION DURING DENITRIFYING PHOSPHORUS REMOVAL IN A TROPICAL CLIMATE
This work aims to increase current knowledge of microbial communities and their metabolic underpinnings in EBPR processes under tropical conditions. Aerobic granulation and alternating carbon sources were used to obtain Accumulibacter enrichment at 30&176C. It was surmised that involvement of …

The Effects of Temperatures on System Performance and Bacterial Community Structure in a Biological Phosphorus Removal System
… results in an increased population of phosphate accumulating organisms (PAOs) relative to non-PAOs and, therefore, greater EBPR efficiency even though the reaction rates are slower. The proliferation of PAOs relative to non-PAOs at cold temperature indicates that some of the PAOs are …
