Abstract

Five strains of Gibberella fujikuroi and Fusarium moniliforme were screened to select G.fujikuroi-52, a strain capable of giving consistent production of gibberellin by solid state fermentation (SSF). The comparative production of GA3 by SSF and Submerged fermentation (SmF) indicated better productivity with the former technique. The accumulation of GA3 was 47.0% higher in SSF than SmF technique. Use of coarse wheat bran of the particle size of 0.3–0.4 cm resulted in 2.5 times increase of the yield of GA3. Consistent and improved yield to a tune of 1.05 g GA3 per kg DMB proved the superiority of SSF technique for the production of GA3 by G. fujikuroi-52.
