Ecophysiology of abundant denitrifying bacteria in activated sludge.
The abundance of potential denitrifiers in full-scale wastewater treatment plants with biological nitrogen and phosphorus removal was investigated by FISH and various oligonucleotide probes. The potential denitrifiers were characterized as probe-defined populations that were able to consume radiolabelled substrate with oxygen, nitrate and nitrite as electron acceptor as determined by microautor...
متن کاملThe significance of denitrifying polyphosphate accumulating organisms in biological nutrient removal activated sludge systems.
In this paper the advantages and disadvantages of denitrifying PAOs (polyphosphate accumulating organisms) in conventional BNRAS (biological nutrient removal activated sludge) and external nitrification BNRAS (ENBNRAS) systems are evaluated, with experimental data exhibiting a range of anoxic P uptake from low (<10%) to very high (>60%). The results indicate that the specific denitrification ra...
متن کاملScreening and Fermentation Characteristics of PHA Bacteria in Activated Sludge
Using sludge at the bottom of Hengshui Lake as samples, and screened out the SJ-9 strain with PHA synthesis capability by enrichment, purification, Nile blue staining, far-infrared spectroscopy and gas qualitative and quantitative analysis. The infrared scanning of SJ-9 bacteria product showed that this product was middle chain PHA. Optimization of SJ-9 fermentation conditions obtained the opti...
متن کاملIsolation and Identification of Anionic Surfactant Degrading Bacteria from Activated Sludge
Linear alkylbenzene sulfonate (LABS) is an anionic surfactant widely used all over the world. They will eventually end-up and accumulate in household or industrial sewage. Due to their high foaming capabilities which can cause numerous problems in sewage treatment facilities as well as direct toxic effects on many different organisms in ecosystem they are generally considered as serious polluta...
متن کاملMicrobial selection of polyphosphate-accumulating bacteria in activated sludge wastewater treatment processes for enhanced biological phosphate removal.
Activated sludge processes with alternating anaerobic and aerobic conditions (the anaerobic-aerobic process) have been successfully used for enhanced biological phosphate removal (EBPR) from wastewater. It is known that polyphosphate-accumulating bacteria (PAB) play an essential role for EBPR in the anaerobic-aerobic process. The present paper reviews limited information available on the metabo...
