Abstract
The effect of kaolin particles on the growth of a bacterium, which was isolated as a dominant one from a continuous culture charged with natural lake water and kaolin particles, was analyzed by means of growth kinetics in batch culture. The presence of kaolin particles brought μm increase and Ks decrease, as compared with the absence of kaolin particles. Such change in the growth parameters was due to concentration of a substrate (histidine) on kaolin particles and attachment of the cells on the particles. This study suggests the possibility that effect on bacterial growth in the presence of the particles is analyzed by means of growth kinetic approach.
