[Glucose consumption and dehydrogenase activity of the cells of the arsenite-oxidizing bacterium Pseudomonas putida].
The rates of glucose assimilation and dehydrogenase activity were studied in Pseudomonas putida oxidizing arsenite. The rate of glucose utilization by the cells decreased in the presence of arsenites in the medium at the beginning because of the microbial adaptation to arsenite. The activity of dehydrogenase fell down when the cells were cultivated in the medium with arsenite. An inverse correlation existed between the rate of glucose assimilation and arsenite oxidation. Apparently, arsenites were oxidized under the action of metabolites produced by P. putida in the process of its heterotrophous growth.
