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 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...
متن کاملProduction and Characterization of Exopolysaccharide Produced by Alcaligenes Faecalis B14 Isolated from Indigenous Soil
Exo-polysaccharides (EPS) are environment friendly natural polymers secreted by microorganisms in the surrounding medium. Due to the presence of unique structural composition, EPS shows diverse applications such as in food formulations, pharmaceutical, and cement based construction industry, etc. In the present investigation, the bacteria producing higher exopolysaccharide was screened among ba...
متن کاملSiderophore production by Alcaligenes faecalis and its application for growth promotion in Arachis hypogaea
A rhizobacterium isolated from groundnut rhizosphere and identified as Alcaligenes faecalis BCCM 2374 produced siderophore during 24 h submerged growth in modified succinic acid medium (SM) prepared in tap water without deferration. For the optimized production of siderophore in the presence of starch and sucrose, the optimum parameters found were as follows: slight acidic pH (5.5), 35C tempera...
