Abstract
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 μg of kinetin per liter.
