| the kinetics of the reduction of isocyanides, acetylenes and the cyanide ion by nitrogenase preparation from azotobacter chroococcum and the effects of inhibitors. | 1. nitrogen-fixing preparations from azotobacter chroococcum reduced substrates with the following k(m) values: methyl isocyanide, 1.8x10(-4)m; ethyl isocyanide, 2.5x10(-2)m; cyanide ion, 1.4x10(-3)m; acetylene, 1.2x10(-4)m. 2. nitrogen, carbon monoxide or hydrogen competitively inhibited isocyanide reduction with the following k(i) values: hydrogen, 1.3x10(-3)m; carbon monoxide, 6.8x10(-6)m; nitrogen, 4.3x10(-4)m. 3. living nitrogen-fixing bacteria, and isolated clover nodules, formed methane f ... | 1968 | 5642620 |

| taxonomy of azotomonas species. | the ability of two strains of azotomonas insolita and one strain classified only as azotomonas species to use molecular nitrogen was investigated by use of several techniques. molecular (15)n(2) incorporation by growing cultures of azotomonas was inconsistent and limited. in addition, attempts to demonstrate nitrogen fixation in growing cultures by the radioactive (13)n(2) technique were negative. experiments were done in which the total nitrogen content of a culture was determined by a micro-kj ... | 1968 | 5636811 |

| encystment and polymer production by azotobacter vinelandii in the presence of beta-hydroxybutyrate. | cells of azotobacter vinelandii encysted in burk's nitrogen-free liquid media which had been supplemented with n-butyl alcohol, beta-hydroxybutyrate, or crotonate. butyraldehyde and butyrate did not influence the extent of encystment. in the absence of glucose, beta-hydroxybutyrate enhanced the rate and extent of encystment. in the presence of glucose, it promoted abortive encystment, which was manifested by the disorganization of the exine and the release of a highly viscous material into the m ... | 1968 | 5669905 |

| occurrence of poly-beta-hydroxybutyrate in the azotobacteriaceae. | poly-beta-hydroxybutyrate (phb) from various representative strains of the genera azotobacter, beijerinckia, and derxia was isolated and characterized. during growth in shake culture, with glucose as a carbon and energy source, and molecular nitrogen as a nitrogen source, increase in dry weight appeared linear, and phb formed a constant percentage of the dry weight. in a medium containing 1% (w/v) glucose, phb declined with the onset of the stationary phase of growth; with 2% (w/v) glucose, an i ... | 1968 | 5650085 |

| 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 |

| regulation of nitrogen fixation in azotobacter vinelandii op: the role of nitrate reductase. | a number of chlorate-resistant mutants were selected, and one of these, clr68-5, was studied in detail. this mutant cannot utilize nitrate in vivo to overcome the effect of nonmetabolizable repressors of nitrogenase. the reason for this inability was that strain clr68-5 lacked nitrate reductase. nitrate inhibited the activity of nitrogenase but did not act as a corepressor of nitrogenase in strain clr68-5 as it does in the wild type. ammonia seemed to act as corepressor of nitrogenase in both st ... | 1969 | 5781587 |
