Summary Volumetric mass transfer coefficients (kLa) were measured by a steady state method in a twin bubble column to characterize the coalescence behaviour of the medium. Employing Hansenula polymorpha cultivation broths, kLa values were compared with those measured in model media in the presence and absence of antifoam agents. The ratio of the volumetric mass transfer coefficient in the system investigated to that in water, $${\text{m = k}}_{\text{L}} {\text{a/(k}}_{\text{L}} {\text{a)H}}_{\text{2}} {\text{O}}$$ , was employed to characterize the cultivation medium.
