Identification of gibberellins A1, A3, and iso-A3 in cultures of Azospirillum lipoferum

Gibberellins A1, A3, and iso-A3 were identified from aseptic cultures of Azospirillum lipoferum strain op 33 by capillary gas chromatography-mass spectrometry (GC-MS) and GC-MS-selected ion monitoring. There were 20 to 40 picograms (in GA3 equivalents, estimated from bioassay) of gibberellins A1 and...

Description
Summary:Gibberellins A1, A3, and iso-A3 were identified from aseptic cultures of Azospirillum lipoferum strain op 33 by capillary gas chromatography-mass spectrometry (GC-MS) and GC-MS-selected ion monitoring. There were 20 to 40 picograms (in GA3 equivalents, estimated from bioassay) of gibberellins A1 and A3 per milliliter of cell culture (containing 10(9) cells)
