Differentiation of Alcaligenes faecalis from Brucella bronchisepticus by biochemical and nutritional methods.
BruceUa bronchisepticus has been variously claified and at present is usually included either in the genus Brucella or the genus Hemophilus. Szturm and Bourdon (1948) have pointed out their inability to differentiate this organism from Alcaligewe faecalis, and we experienced the same difficulty in our laboratories. Reference to Bergey's Manual of Determinative Bacteriology, edition 6, offered n...
متن کاملThe First Study of Investigation of Clinical Isolates of Alcaligenes Xylosoxidans and Alcaligenes Faecalis by Phenotypic and Genetic Methods in Iran
Background and Objective: Alcaligenes sp. is a non-fermentative Gram-negative bacillus, which causes nosocomial infections, including urinary tract infections, pneumonia, sepsis, and may be confused with Pseudomonas aeruginosa. Alcaligenes infections usually are not well identified and due to possible errors and similarities with Pseudomonas, their diagnosis with phenotypic tests is not suffici...
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; ...
