Abstract

BACKGROUND: Oxygen mass transfer can be described and analyzed by means of the mass transfer coefficient k(L)a, which is the most important parameter involved in the design and operation of mixing-sparging equipment for bioreactors. In the present study, the effect of biomass support materials on the gas-liquid mass transfer coefficient was studied in a bioreactor under variable process conditions. The biomass support materials used were activated carbon, pumice and loofa sponge.
