Recently, several different types of devices have been developed which automatically record oxygen consumption of biological cultures. This article describes one of these devices and discusses its application.
Oxygen utilization is defined in this investigation as the terminal use of oxygen in respiration, i.e., the formation of water. A culture of Pseudomonas fluorescens was allowed to respire in an atmosphere of O(18). The production of H(2)O(18) was measured during two test runs of 124 and 232 min each. During the first run, 0.505 mmole of H(2)O(18) was produced. The second run produced 0.460 mmole of H(2)O(18). H(2)O(18) production took place throughout the course of each of the runs.
