(university of texas, austin), and orville wyss. chelation effects on azotobacter cells and cysts. j. bacteriol. 91:120-124. 1966.-ethylenediaminetetraacetate (edta) is very toxic to azotobacter in the presence of nitrogen compounds that form complexes with it. this appears to be due to stronger chelation of certain metal ions by the complex. when such complexes of edta and nitrogen compound are absent, azotobacter cysts can be ruptured by chelation without being killed ... | 1966 | 4955245 |
central body of the azotobacter cyst. | parker, laura t.

conversion of ddt to ddd by pathogenic and saprophytic bacteria associated with plants. | of 27 microorganisms examined, 23 plant pathogenic and saprophytic bacterial species were found to convert p,p' ddt to p,p' ddd under anaerobic conditions. the range of conversion of ddt (10 micrograms per milliliter) during an incubation of 14 days was from a trace to over 5 micrograms per milliliter, with the majority of the bacteria showing the greatest activity during the final 7-day period. there is evidence that metabolites of ddt other than ddd are also produced. | 1967 | 4961613 |

cytochrome c oxidation by the electron transport fraction of azotobacter vinelandii. | the spectrophotometric oxidation of horse heart ferrocytochrome c was examined by use of the particulate electron transport fraction (r(3)) of azotobacter vinelandii strain o. unlike cytochrome c, purified preparations of native azotobacter cytochromes c(4) + c(5) were oxidized only slowly by the electron transport fraction. the oxidation of mammalian cytochrome c proceeded at an appreciable rate and displayed "apparent" first-order kinetics at a ph optimum of 9.0 with tris(hydroxymethyl)aminome ... | 1968 | 4967774 |
effect of ion concentration on the rupture and survival of azotobacter cysts. | the ability of ethylenediaminetetraacetic acid (edta) and dipicolinic acid (dpa) to rupture azotobacter cysts was directly related to the molarity of the reaction mixture. cysts were not ruptured at concentrations above 0.15 m (nacl or phosphate). these higher salt concentrations prevented the formation of metallo:edta (or dpa) chelate complexes. sudden shifts in the tonicity of nacl or phosphate mixtures induced cyst rupture in the absence of edta. the effect of these mechanisms on the survival ... | 1968 | 4969661 |

l-malate oxidation by the electron transport fraction of azotobacter vinelandii. | the membrane-bound l-malate oxidoreductase of azotobacter vinelandii strain o was found to be a flavoprotein-dependent enzyme associated with the electron transport system (r(3)) of this organism. the particulate r(3) fraction, which possessed the l-malate oxidoreductase, carried out the cyanide-sensitive oxidation of l-malate, d-lactate, reduced nicotinamide adenine dinucleotide and nicotinamide adenine dinucleotide phosphate, succinate, cytochrome c, tetramethyl-p-phenylenediamine, and p-pheny ... | 1969 | 4977982 |
preparation and ultrastructure of the outer coats of azotobacter vinelandii cysts. | cysts of azotobacter vinelandii were ruptured with 3.0 mm ethylenediaminetetraacetate in 0.05 m tris(hydroxymethyl)aminomethane buffer (ph 7.8) and fractionated by differential centrifugation in density gradients of sucrose or ficoll (polysucrose) at 10,000 x g for 2 hr at 4 c. the average densities of the cyst exine, the cyst central body, the vegetative cell, and the intact cyst were found to be 1.13, 1.26, 1.28, and 1.31 g/cm(3) in sucrose, and 1.08, 1.12, 1.13, and 1.17 g/cm(3) in ficoll, re ... | 1969 | 4977988 |

nitrogenase activity in cell-free extracts of the blue-green alga, anabaena cylindrica. | cell-free extracts with high nitrogenase activity were prepared by sonic oscillation and french press treatment from the blue-gree alga anabaena cylindrica. extracts were prepared from cells grown on a 95% n(2)-5% co(2) gas mixture followed by a period of nitrogen starvation under an atmosphere of 95% argon-5% co(2). no increase in the specific activity of extracts was achieved by breaking heterocysts. activity (assayed by acetylene reduction) was found to be dependent on adenosine triphosphate ... | 1971 | 4994040 |

effect of nitrogenase components from mutant and wild-type strains of azotobacter on the dilution effect of nitrogenase. | nitrogenase activity exhibits a dilution effect. evidence is presented that the reason for the dilution effect is that one of the component proteins of nitrogenase is limiting in preparations of this enzyme. the limiting component appears to be the non-haem-iron-containing protein (also called fraction ii, iron protein, azoferredoxin), which is equivalent to the enhancement factor for nitrogenase activity present in extracts of nitrogenaseless mutant 22r1. a mathematical function of specific act ... | 1971 | 5118103 |
