Abstract

The evolution of volatile compounds produced during solid substrate cultivation (SSC) of Gibberella fujikuroi on wheat bran was tracked looking for volatile metabolites related with GA(3) production. Ethyl acetate and isoamyl acetate gave identical profiles and sharp increases that abated as the production of GA(3) began, while ent-kaurene displayed a profile matching that of the development of GA(3). ent-Kaurene is a precursor in the synthesis of gibberellins and was the most abundant compound found.
