Cytokinins in Azotobacter vinelandii Culture Medium.
نویسندگان
چکیده
Azotobacter vinelandii OP was grown to stationary phase in defined medium. The cell-free culture medium was analyzed for cytokinin content by XAD-2 and Sephadex LH-20 chromatography, thin-layer chromatography, tobacco callus bioassay, and enzyme immunoassay. Three cytokinin-active fractions were detected and tentatively identified as trans-zeatin, isopentenyladenosine, and isopentenyladenine. The total cytokinin activity was equivalent to 0.75 mug of kinetin per liter.

Presence of 2-methylthioribosyl-trans-zeatin in Azotobacter vinelandii tRNA.
Hydroxylated cytokinin, 2-methylthio-N6-(4-hydroxy-3-methylbut-2-enyl) adenosine, was found in the tRNA of Azotobacter vinelandii. This cytokinin had the trans configuration, unlike the cis configuration reported for that from other bacteria. Culture-condition-dependent changes in the content of this thiocytokinin and a few other thionucleosides in the tRNA of this bacterium have been observed.
متن کاملEffect of peptone on Azotobacter morphology.
Pleomorphism in cultures of Azotobacter vinelandii was induced by addition of Difco peptone to the growth medium. Under the conditions of the study, 5% peptone gave rise to transient forms described as "fungoid cells" which were osmotically fragile. After some 48 hr of culture, they became osmotically stable and resumed a more typical morphology. It was shown that the pleomorphism-inducing prin...
متن کاملSiderophores Produced by Nitrogen-Fixing Azotobacter vinelandii OP in Iron-Limited Continuous Culture.
Azotobacter vinelandii requires a high complement of iron and an efficient iron acquisition system to support nitrogen fixation. To circumvent problems inherent in batch culture trace metal studies, continuous cultures were used to measure the response of A. vinelandii to iron stress. Iron was found to be growth limiting for nitrogen-fixing A. vinelandii at a concentration as high as 12.5 muM; ...
متن کاملFeedback inhibition of nitrogenase.
No inhibition of nitrogenase activity by physiological levels of NH4+ or carbamyl phosphate was observed in extracts of Azotobacter vinelandii. All of the 15N2 reduced by cultures which received no NH4+ was found in the cells. By contrast, more than 95% of the 15N2 reduced by cultures which had been given NH4+ was found in the medium. Failure to examine the culture medium would lead to the erro...
متن کاملEndogenous 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 desiccati...
