Phenanthrene-degrading phenotype of Alcaligenes faecalis AFK2.
A phenanthrene-degrading bacterium that assimilated a wide range of organic compounds was isolated from a soil sample and identified as Alcaligenes faecalis strain AFK2. The strain degraded phenanthrene through protocatechuate, but did not utilize naphthalene. The phenanthrene-degrading phenotype (Phn+) of AFK2 disappeared after 20 successive subcultures in a mineral salts medium containing o-p...
متن کاملNitrogen 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, ...
متن کاملMicrobial 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 ...
متن کاملOxidation of arsenite to arsenate by Alcaligenes faecalis.
Alcaligenes faecalis, resistant to the toxic effects of 0.01 M sodium arsenite, was isolated from raw sewage and shown to be capable of oxidizing arsenite to arsenate. When the organisms were grown in chemically defined medium, this conversion was due to the appearance at stationary phase of an intracellular, oxygen-sensitive, inducible enzyme and/or component of the electron transport system; ...
متن کاملD-erythrose metabolism in a strain of Alcaligenes faecalis.
Except for the oxidation of erythritol to L-erythrulose by Acetobacter (Bertrand, 1900) little is known of the metabolism of tetroses in microorganisms. Barker and Lipmann (1949) found erythritol to be esterified and oxidized by Propionibacterium pentosaceum, although a tetrose intermediate was not identified. The utilization of D-erythrose by mammalian liver slices has been reported by Abraham...
