The separation efficiency of certain substances, such as acetone and isopropanol in a trickle-bed bioreactor, depends strongly on the oxygen concentration. The results obtained can be described by a mathematical model based on the diffusion of oxygen into the biofilm (diffusion regime of the catalyst). The non-stationary operation of the reactor - interruption of the oxygen stream and strong fluctuation in the exhaust gas stream - showed that other components, such as propionaldehyde and n-propanol, could be eliminated for a certain time without oxygen. Propionic acid is formed. Finally a technical biofilter is compared with a trickle-bed bioreactor. 4 refs., 5 figs., 1 tab.
