The Metabolism of Xanthine-8-carboxylic Acid by Alcaligenes Faecalis.
Alcaligenes jaecalis is capable of growing in response to simple pteridines as the sole source of nitrogen (1). Simple pteridines appear to be metabolized in this organism through the common intermediate, tetraoxypteridine (1, 2)) and cell-free extracts of the organism catalyze the conversion of tetraoxypteridine to xanthine-8-carboxylic acid (1). In these conversions the nitrogen atoms of the ...
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 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 کاملFactors affecting the formation of gum by Alcaligenes faecalis.
Maleic hydrazide (1, 2-dihydropyridazine-3, 6dione) is an organic plant growth regulator which has found use in such varied areas as prevention of sucker formation in tobacco, prevention of sprouting of some stored vegetables, and as a herbicide. In commercial application the diethanolamine salt (diethanolammonium maleic hydrazide or diethanolammonium-1 ,2-dihydropyridazine-3, 6-dione) is often...
