title: [The tenacity of air-borne bacteria. II. Communication: Experimental investigations carried out for determining the kill constant beta biol for cocci (author's transl)].
abstract: The kill constants beta biol. for cocci are determined in a static aerosol chamber. To do this, the particle diminution (living and dead colony-forming units, KE) is determined with a scattered light photometer and the decrease in reseedability of the colony-forming units is measured by a six-stage Andersen collector. The difference is the kill constant beta biol. which is independent of the physical diminution. For use with model calculations it is recommended that limit values should be assumed which realistically express the wide scatter range of the values.
