OXIDATIVE ASSIMILATION BY AZOTOBACTER AGILIS

Induced biochemical mutants to Azotobacter agilis.

Oxidative assimilation by Bacillus subtilis.

It is a common observation that the oxidation of many substrates is not carried to completion by various species of microorganisms and that instead a portion of the substrate is assimilated by the cells. In those species possessing a high level of endogenous respiration and in which the rate of respiration is not increased markedly following the addition of a utilizable substrate, oxygen consum...

Metabolic Studies of Azotobacter Agilis by the Use of a Mutant Deficient in Pyruvic Oxidase*

An account has been given elsewhere of the successful isolation of physiological x-ray mutants of Azotobacter agilis with genetic blocks in the substrate oxidation mechanisms (1). The present paper deals in greater detail with a mutant strain, designated A13, that was isolated as a variant unable to grow on glucose, and gives the methods used to characterize the particular deficiency responsibl...

Acetate assimilation by Nitrobacter agilis in relation to its "obligate autotrophy".

Acetate (1 to 10 mm) had no effect on the rate of nitrite oxidation or exponential growth by Nitrobacter agilis. However, acetate-1-(14)C and -2-(14)C were both assimilated by growing cultures, and acetate carbon contributed 33 to 39% of newly synthesized cell carbon. Carbon from acetate was incorporated into all of the major cell constituents, including most of the amino acids of cell protein ...

Oxidative Assimilation of Glucose by Pseudomonas Aeruginosa.

Duncan, Margaret G. (The University of British Columbia, Vancouver, British Columbia, Canada) and J. J. R. Campbell. Oxidative assimilation of glucose by Pseudomonas aeruginosa. J. Bacteriol. 84:784-792. 1962-Oxidative assimilation of glucose by washed-cell suspensions of Pseudomonas aeruginosa was studied using C(14)-labeled substrate. At the time of glucose disappearance, only small amounts o...
