Abstract
A new method of producing a mixture of gibberellins which is predominantly GA,and GA,but also contains GA,has the steps of providing a seed of,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,Strain LTB-1027 from the culture broth, and extracting the gibberellins to produce a gibberellin mixture which is at least 50% GA,and GA,. The method produces a gibberellin mixture in which the combined titer of GA,and GA,exceeds 800 mg/liter. The production method also produces a gibberellin mixture with approximately equal titers of gibberellins GA,and GA,. A variation of the method produces a gibberellin mixture which contains over 40% GA,.
