the isolation of nitrosomonas and nitrobacter by the single cell technique. 193017799073
the presence of an endogenous respiration in the autotrophic is shown that there exists in the autotrophic bacterium thiobacillus thiooxidans a measurable oxygen uptake in the absence of the specific nutrient (sulfur). this respiration is shown to be due to the utilization of organic materials which must have been previously synthesized by the chemosynthetic process, providing evidence that autotrophic bacteria contain a dissimilatory process which involves the breakdown of organic materials and furnishes energy for the maintenance of the cell during p ...194219873300

the effect of 2,3,6-trichlorophenylacetic and 2,2-dichloropropionic acids on nitrite oxidation.the effects of two herbicides, 2,3,6-trichlorophenylacetic acid, sodium salt, and 2,2-dichloropropionic acid, sodium salt, on nitrite-oxidizing bacteria were studied by the soil perfusion technique. the time of application of 2,3,6-trichlorophenylacetic acid affected its toxicity to the nitrifier. when it was present in the environment as the nitrifier started growth, it was more toxic than if the organisms were allowed to nitrify actively before they were subjected to the herbicide. the herbici ...196214471731

(cornell university, ithaca, n.y.), and m. alexander. permeability of nitrobacter agilis to organic compounds. j. bacteriol. 90:151-156. 1965.-none of a variety of inorganic ions or organic compounds served as a sole energy source for the growth of nitrobacter agilis, and the test substrates were not oxidized by either intact cells or extracts of the obligate chemoautotroph. the organic substances did not serve as sole carbon sources for the bacterium in a synthetic medium, and they fail ...196516562012

(goucher college, baltimore, md.), and helen b. funk. stimulation of nitrobacter agilis by biotin. j. bacteriol. 90:729-733. 1965.-addition of biotin to nitrite-mineral medium greatly stimulated the autotrophic growth of four strains of nitrobacter agilis. comparisons of cultures of the organisms grown in parallel at 30 c in nitrite medium and in the medium supplemented with 150 mmug of biotin per ml showed that the vitamin promoted: (i) 2- to 4-fold greater rates of utilizati ...196516562074

oxygen-nitrogen relationships in autotrophic nitrification.oxygen utilization by the autotrophic nitrifiers nitrosomonas and nitrobacter was studied. experimental evidence is presented which reflects the effect of carbon dioxide fixation on overall oxygen utilization in autotrophic nitrification. measurement of dissolved oxygen and inorganic nitrogen changes indicates that oxygen-nitrogen ratios in inorganic nitrogen oxidation are equal to 3.22 parts (expressed in milligrams per liter) of oxygen per part of ammonia nitrogen oxidized to nitrite nitrogen ...19676077417

spectrophotometric and kinetic study of nitrite and formate oxidation in nitrobacter winogradskyi.the reduction levels of cytochrome c and a(1) in intact nitrobacter cells and cell-free extracts, during and after nitrite or formate oxidation, were examined in combination with the amperometric measurement of oxygen uptake. quite different reduction patterns were observed when comparing nitrite oxidation by intact cells and cell-free extracts. an inverse relationship was observed between the rate of electron flow and the steady-state reduction level of cytochrome a(1). parallel observations on ...19674289808

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 and poly-beta-hydroxybutyrate (phb). cultures grown in the presence of acetate showed a significant inc ...19685643062

nitrite oxidase and nitrate reductase in nitrobacter agilis.nitrite oxidase and nitrate reductase in nitrobacter agilis were shown to be separate enzymes. the best separation of the two systems was achieved by ammonium sulphate fractionation. the effects of various compounds, including antimycin a, 2-n-heptyl-4-hydroxyquinoline n-oxide and chlorate, also clearly distinguish between the two enzyme reactions. the relationship between the two opposing reactions in nitrobacter is discussed.19695807206

ultrastructure of nitrobacter agilis grown under autotrophic and heterotrophic conditions.nitrobacter agilis, grown through seven transfers heterotrophically in the absence of nitrite, was examined in the electron microscope. the ultrastructure of such cells closely resembled that of autotrophically grown n. agilis. it was thus futher established that the organisms growing heterotrophically were indeed n. agilis and, therefore, that n. agilis is a facultative autotroph. acetate incorporation into poly-beta-hydroxybutyrate was confirmed cytologically.19695773036
