【 摘 要 】

Gibberellic acid (GA3) is an important hormone, which controls plant's growth and development. Solid State Fermentation (SSF) allows the use of agro-industrial residues reducing the production costs. The screening of strains (four of Gibberella fujikuoroi and one of Fusarium moniliforme) and substrates (citric pulp, soy bran, sugarcane bagasse, soy husk, cassava bagasse and coffee husk) and inoculum preparation study were conducted in order to evaluate the best conditions to produce GA3 by SSF. Fermentation assays were carried out in erlenmeyers flasks at 29°C, with initial moisture of 75-80%. Different medium for inoculum production were tested in relation to cells viability and GA3 production by SSF. F. moniliforme LPB 03 and citric pulp were chosen for GA3 production. The best medium for inoculum production was citric pulp extract supplemented with sucrose. GA3 production by SSF reached 5.9 g /kg of dry CP after 3 days of fermentation.
