Abstract

To study the effect of the cell fraction f on diffusion an artificial biofilm was developed, consisting of an agar matrix contg. monodisperse impenetrable polystyrene particles with the same diam. as bacteria (1 mm). Diffusion of glucose at different polystyrene fractions was measured in two ways: with a micro-electrode the transient response on a concn. step in the well mixed bulk was recorded in time and in a classical diffusion cell the flux through a flat film was measured. Detn. of the diffusion coeff. with a micro-electrode was shown to be accurate and, therefore, a good addn. to the usual macroscopic methods. The decrease of the diffusion coeff. with increasing polystyrene fraction (0-28 % vol./vol.) was larger as expected. This might be related to an inhomogeneous distribution of the polystyrene particles in the agar and is currently under investigation. [on SciFinder (R)]
