Gradually supply of isoamyl alcohol increases the isoamyl acetate production in solid-state fermentation.

Nowadays, isoamyl acetate production is carried out by chemical synthesis with a recent interest in developing biological producing processes, mainly based on microorganisms in submerged fermentation. This work assayed producing isoamyl acetate through solid-state fermentation (SSF), feeding the precursor in the gas phase. Polyurethane foam functioned as the inert support to contain 20 ml of a solution of molasses (10% w/v, pH 5.
