| cytochrome and ubiquinone patterns during growth of azotobacter vinelandii. | after synthesis during the early log phase, the concentrations of ubiquinone and cytochromes did not vary during the growth cycle of azotobacter vinelandii, when grown with either high or low aeration on nitrogen-free or urea-containing media. the level of aeration had no effect on the concentrations of the electron carriers synthesized, but affected the growth rate. on urea-containing medium, the concentration of cytochrome a(2) was low, but it was synthesized at a linear rate when the bacteria ... | 1969 | 5773028 |

| hydrogenase measurement with photochemically reduced methyl viologen. | methyl viologen was reduced photochemically in the presence of proflavine and ethylenediaminetetraacetic acid. the reduced methyl viologen was oxidized by hydrogenase from vibrio succinogenes. h(2) and oxidized methyl viologen were the products. hydrogenase activity was determined by spectrophotometric measurement of the disappearance of reduced methyl viologen at 600 nm. the extinction coefficient of reduced methyl viologen was determined and is 8.25 mm(-1) x cm(-1) at 600 nm. optimal condition ... | 1969 | 5781586 |
| 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 |

| correlation of ultrastructure in azotobacter vinelandii with nitrogen source for growth. | azotobacter synthesizes an extensive internal membranous nework when grown with air (n(2)), i.e., under conditions when these bacteria fix nitrogen. very slight quantities of internal membrane, concentrated mainly about the cell periphery, are formed when azotobacter grows with fixed nitrogen, i.e., ammonia and amino acids. compared to cells growing with ammonia, cells utilizing atmospheric nitrogen as the sole nitrogen source are smaller in size and volume, grow one-third slower, and lack detec ... | 1970 | 5411753 |
