Sludge biochar can be used as bio-carrier to enhance aerobic granular sludge, however, its impact on the formation and especially long-term stability of granules has not been fully investigated. In this paper, sludge was cultivated in two parallel sequencing batch reactors (SBRs), R1 R2, with without addition activated inoculum, respectively. The characteristics, wastewater treatment performanc...

BACKGROUND While aerobic glycolysis is linked to unconstrained proliferation in cancer, less is known about its physiological role. Why this metabolic program that promotes tumor growth is preserved in the genome has thus been unresolved. We tested the hypothesis that aerobic glycolysis derives from developmental processes that regulate rapid proliferation. METHODS We performed an integrated ...

This study evaluates the community structure in nitrifying granules (average diameter of 1600 mum) produced in an aerobic reactor fed with ammonia as the sole energy source by a multivalent approach combining molecular techniques, microelectrode measurements and mathematical modelling. Fluorescence in situ hybridization revealed that ammonia-oxidizing bacteria dominated within the first 200 mum...

Experimental work was carried out to investigate the influence of impeller speed, granulation time, binder mass and their interactions on granule size distribution, mean size and binder content distribution in a conical high shear granulator. It was observed that the response of high shear granulation to changes in process parameters varies significantly from one operating condition to anot...

Abstract The presence of toxic compounds in wastewater can cause problems for organic matter and nutrient removal. In this study, the long-term effect a model xenobiotic, 2-fluorophenol (2-FP), on ammonia-oxidizing bacteria (AOB), nitrite oxidizing (NOB) phosphate accumulating organisms (PAO) aerobic granular sludge was investigated. Phosphate (P) ammonium (N) removal efficiencies were high (&a...

In this study, aerobic granular reactor (AGR) was used to treat landfill leachate by changing the concentrations of chemical oxygen demand (COD) (668 ± 110-1149 93 mg/L), ammonia (NH 3 –N) (30 3.3-48 1.3 and phosphorus (PO 4 –P) (147 18-221 17 mg/L). The average COD removal gradually reduced from 81 75%, increasing 668 110 1149 mg/L. phase I, maximum (94%) NH –N (85%) were observed at influent ...

The characteristics of neurosecretory granules include the presence of an acidic interior, a hyperosmolar concentration of granule solutes, the presence of chromogranin (CG) or CG-like soluble acidic proteins and a high content of nucleotides, predominantly ATP. The identification of "nucleotides" within the neuroendocrine "stem cells" of coelenterates (e.g. Hydra) has raised some interesting e...
