The Formation of a Model Floc Able to Decompose Phenol by the Mixed Culture C)f Bacteria Isolated from Activated Sludge
نویسندگان
چکیده
Several floc-forming bacteria and phenol-decomposing bacteria were isolated from a phenol-adapted activated sludge. Strain No. 12 was the best floc-former and the ratio of flocculated cells to total cells was 90 or more. A model floc was formed by the mixed culture of the strain No. 12 and No. 3, which was one of representative strains of phenoldecomposing bacteria. This model floc can successfully decompose such a high concentration of phenol as 700 ppm, though the strain No. 3 in pure culture did not show any detectable phenol decomposition or did not even grow at that concentration of phenol.

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...

Although the activated sludge process for stabilizing liquid organic wastes is primarily a biological process, very little research has been conducted on the pure biological phases of this process. Until the work of Butterfield (1935), activated sludge was considered by some as a physio-chemical process and by others as a bio-chemical process. Butterfield isolated a bacterium, Zoogloea ramigera...

Activated sludge is widely used to treat municipal and industrial wastewater globally and the formation of activated sludge flocculates (flocs) underpins the ability to separate sludge from treated water. Despite the importance of activated sludge flocs to human civilization there have been precious few attempts to rationally design fit for purpose flocs using a bottom-up approach based on a so...

This paper indicates that activated sludge under certain conditions can achieve levels of polyhydroxyalkanoates (PHA) accumulation which would enable the economic recovery of this precursor of biodegradable plastics. The effects of C/N ratio and temperature on polyhydroxyalkanoates production were evaluated. Acetate uptake, ammonium consumption, oxygen uptake and PHA production were studied und...

DNA was isolated from phenol-digesting activated sludge, and partial fragments of the 16S ribosomal DNA (rDNA) and the gene encoding the largest subunit of multicomponent phenol hydroxylase (LmPH) were amplified by PCR. An analysis of the amplified fragments by temperature gradient gel electrophoresis (TGGE) demonstrated that two major 16S rDNA bands (bands R2 and R3) and two major LmPH gene ba...
