Production of high titers of gibberellins, GA4 and GA7, by Gibberella fujikuroi strain LTB-1027 |
摘要 |
A new method of producing a mixture of gibberellins which is predominantly GA4 and GA7 but also contains GA3 has the steps of providing a seed of Gibberella fujikuroi Strain LTB-1027 or mutants derived therefrom, inoculating the seed into a culture medium rich in carbohydrate and relatively low in nitrogen, incubating the culture for at least four days, separating the Gibberella fujikuroi Strain LTB-1027 from the culture broth, and extracting the gibberellins to produce a gibberellin mixture which is at least 50% GA4 and GA7. The method produces a gibberellin mixture in which the combined titer of GA4 and GA7 exceeds 800 mg/liter. The production method also produces a gibberellin mixture with approximately equal titers of gibberellins GA4 and GA7. A variation of the method produces a gibberellin mixture which contains over 40% GA4.
