Production Method ga3 giberelinas by fermentations with the wild strain of Gibberella fungus imi58289 fujikuroi.

摘要

Production method gibberellin {3} Ga by fermentations with the wild strain Gibberella fujikuroi IMI58289 fungus.; It is object of this invention a method for the production of gibberellins with the wild strain Gibberella fujikuroi IMI58289 of, without previous genetic manipulation of the fungus. First, the strain is inoculated IMI58289 for 6 days in medium rich in nitrogen, conditions under which the production of gibberellins is inhibited. After six days, the cultures are filtered and the mycelium was washed with distilled water and resuspended in a glucose solution with microelements. Subsequent incubation under these conditions results in a mixture of gibberellins with an unusually high proportion of {3} Ga.
