Improved GA1 production by Fusarium fujikuroi

Recent studies into gibberellin A(1) (GA(1)) showed it to be physiologically more active than GA(3) in plants of great agricultural interest, such as tomatoes, rice, peas, and sweet cherries. We describe here a simple procedure for obtaining large quantities of GA(1) (1,500 mg/l) by incubating the F...

Description
Summary:Recent studies into gibberellin A(1) (GA(1)) showed it to be physiologically more active than GA(3) in plants of great agricultural interest, such as tomatoes, rice, peas, and sweet cherries. We describe here a simple procedure for obtaining large quantities of GA(1) (1,500 mg/l) by incubating the FKMC1995 strain of Fusarium fujikuroi in a standard complex medium (SCM). We also compare the GA production of this strain with that of two other wild-type strains of F. fujikuroi (IMI58289, m567) in SCM and low-nitrogen medium and discuss the possible biogenetic mechanisms involved in the over-accumulation of GA(1) by FKMC1995.
