Optimization of gibberellic acid production by immobilized Gibberella fujikuroi mycelium in fluidized bioreactors.


An orthogonal experimental design L9 (3(4)) was used to investigate effects of temperature, pH, C:N ratio (glucose-C, NH4Cl-N) and concentrations of rice flour on production of gibberellic acid by Gibberella fujikuroi in 3.5 l fluidized bioreactors. The gibberellic acid production in a fluidized bioreactor could reach 3.90 g l(-1), more than 3-times greater… (More)
