| 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 |

| endogenous encystment of azotobacter vinelandii. | when young cells of azotobacter vinelandii are impinged on membrane filters, washed free of carbon substrate, and placed on a mineral salts basal medium, the culture will proceed to encyst although at a slower rate than if n-butanol were supplied as a substrate. the endogenous cysts are depleted in polybeta-hydroxybutyrate and have a narrower intine but show an increased resistance to desiccation and are susceptible to lysis by chelating agents. membrane-supported cells reveal details of the enc ... | 1969 | 5344107 |
| surface structure of azotobactervinelandii cysts as revealed by freeze-cleaving. | micrographs of freeze-cleaved azotobacter vinelandii cysts reveal that the surface is composed of several overlapping layers. this observation is consistent with the previously proposed structure of the outer cyst coat. | 1969 | 5359611 |

| the electron transport system in nitrogen fixation by azotobacter. i. azotoflavin as an electron carrier. | a flavoprotein, named azotoflavin, was isolated from an extract of azotobacter vinelandii cells, which linked the reducing power generated by illuminated spinach chloroplasts to the azotobacter nitrogen-fixing enzyme complex. the photoreduction of the yellow azotoflavin by chloroplasts produced a stable, free-radical semiquinone, blue in color, with properties similar to those described by other investigators for an azotobacter flavoprotein of unknown biological function. | 1969 | 5264138 |

| morphogenesis of cysts in azotobacter vinelandii. | cultures of azotobacter vinelandii were induced to encystment with beta-hydroxybutyrate. the morphological events in the transition from cell to cyst were observed by electron microscopy of thin sections. upon induction of encystment, cells became rounded and nonmotile. the exine coat developed by the continuous excretion of membranous components into the capsule surrounding the cell. | 1970 | 5473905 |
