The present work includes an exhaustive study about gas–liquid interfacial area between gas phase and liquid heterogeneous medium generatedin an airlift bioreactor. The system studied is composed by water, methyl ricinoleate (MR), and Tween-80, since it is the base of the medium usedfor the production of γ-decalactone, a peach-like aroma compound of industrial interest that can be produced biotechnologically through thebiotransformation of ricinoleic acid, by the yeast Yarrowia lipolytica. Experimental results allowdescribing the hydrodynamic behaviour of the gasphase into the biphasic medium.
