Simultaneous Removal of High-Strength Ammoniumand Phosphorus by Alcaligenes faecalis No. 4

Alcaligenes faecalis No. 4 (No. 4), which conducts heterotrophic nitrification and aerobic denitrification, removed 800 mg-N/l of highstrength ammonium and 100 mg-P/l of phosphorus, both in a synthetic medium and in an anaerobically digested municipal sludge solution. The estimated N2 conversion ratio from ammonium-nitrogen was approximately 50%. When the initial phosphorus concentration was re...

Removal of High-Strength of Ammonium and Phenol from Coking Wastewater by Alcaligenes Faecalis No.4

Alcaligenes faecalis No.4, which is capable of heterotrophic nitrification and aerobic denitrification was used to treat coking wastewater (CW) to remove high-strength of ammonium and phenol. First, the phenol-degrading ability of No.4 was verified and a synthetic medium containing lactate and phenol as carbon sources was subsequently applied to the No.4 culture. Both carbon materials were enti...

Heterotrophic Nitrification and AerobicDenitrification of a Wastewater from a ChemicalCompany by Alcaligenes faecalis No.4

A wastewater from a chemical company (abbreviated as WC) containing approximately 5000 mg NH4-N/L ammonium and a slight amount of BOD was treated with Alcaligenes faecalis No.4 (No.4),which is capable of heterotrophic nitrification and aerobic denitrification. The repeatedbatch operation was conducted at 30°C for 900 h at controlled dissolved oxygen concentration (DO) of 2-3 mg/L in the presenc...

Nitrogen compounds utilized by Alcaligenes faecalis.

Conn (1942) observed that Alcaligenes faecalis required organic nitrogen, but as observed by Porter (1946) no report was found of a study of nitrogen compounds suitable for continued growth of A. faecalis. It was reported, however, that this organism grew in a medium containing NH4 lactate as a source of nitrogen and carbon (Braun and Cahn-Bronner, 1921), and used NH4NO3, asparagine, cysteine, ...

Microbial Enhanced Oil Recovery Using Biosurfactant Produced by Alcaligenes faecalis

A bacterial strain (designated as Alcaligenes sp. MS-103) isolated from oil sample of the Aghajari oilfield in the south of Iran, was able to produce an effective extracellular lipopolysaccharide biosurfactant (1.2±0.05 g/l) on molasses as a sole carbon source. The highest surface tension reduction to level 20 mN/m was achieved by biosurfactant produced by cells grown on molasses under optimum ...
