Abstract

Continuous monitoring of a bacterial culture for pH, growth, CO₂, and NH₃ has been accomplished by means of in situ probes. Changes in the metabolic parameters of Proteus cultures generally occurred about an hour before changes in growth were observed. The time of maximum CO₂ production preceded that of NH₃ elaboration by this organism; however, the sequence was reversed when urea was added to the medium. This type of in situ monitoring system has great potential for the study of the metabolism of growing organisms as well as for the early detection of growth in liquid culture.
