An apparatus has been developed to determine the efficiency by which bacteria scavenged and attached to a bubble are transferred upon bubble bursting to the jet drops. Experiments were done by letting bubbles of 625‐ µ m diameter rise about 27 cm through a suspension of Serratia marcescens. The transfer efficiency varied between 50 and 100% and was an inverse function of the concentration of bacteria in the water through which the bubbles rose.
