Studies on the adsorption of four kinds of bacteria,Staphylococcus aureus, Sarcina lutea, Escherichia coli andSerratia marcescens by activated Korean kaolins have been carried out to innovate utilization as adsorbent preparations. In connection with particle size and size fraction, the adsorption was examined by colony counting and spectroscopy. Korean kaolin was purified from Hadong white species of preminum grade and three size fractions were derived from passage through BS# 100, #200 and #325 mesh sieves, respectively. These were activated at 105° or 280° for three hours and at 550 °C for one hours. The results indicated that the adsorbing power of Korean kaolin was superior forS. aureus andS. lutea, butE. coli andS. marcescens were not adsorbed by clays. The smaller the particle size, the greater was adsorbing power for Gram-positive bacteria. There appears to be justification for its further investigations as an ingredient in intestinal adsorbent preparations.
