An air bubble rising through a bulk suspension of bacteria can be made to rise into a tube containing sterile water, which can then be cultured to determine the number of bacteria carried by the bubble. If the distance of bubble rise is varied, data are obtained from which one can calculate both the attachment rate of bacteria to the bubble and the collection efficiency. For a bubble of about 1‐mm diameter rising through a suspension of Serratia marcescens, the collection efficiency is about 0.1%.
