The invention discloses a mutant strain of Gibberella fujikura with high production of gibberellin GA 3 - rice bakanae GA-251 and its application; , deposited in the China Center for Type Culture Collection, address: Wuhan University, Wuhan, China, zip code 430072, preservation number: CCTCC NO: M 2019201, preservation date March 25, 2019. The strain was obtained by compound mutagenesis of protoplasts with lithium chloride and cobalt 60 radiation, and the gibberellin GA 3 production of this strain was increased by 20%. The method has the advantages of high titer, easy extraction of the final product, etc., and overcomes the shortcomings of low fermentation titer and high cost of the original process. |
