An infusion-filtrate method for a continuous supply of air-borne bacteria is described, using either hay, soil, rice, or alfalfa for the infusion-filtrate bacterial cultures. Four cc of autoclaved infusion filtrate provided 1 cc of available bacteria each day. Three experiments each for hay, rice, soil, and alfalfa filtrate for periods of 31 and 60 days are described.
