✦ Synopsis
The use of the bacterial cell for the investigation of the energetics of cellular metabolism may lead to valuable observations in two fields of research. First, the results obtained contribute to the knowledge of the physiology of the organism under investigation, and secondly, the data may be considered as a contribution to the field of general cellular physiology. This fact was recognized in the early days of metabolic research and Rubner ( '02, '03, '04, '06) investigated the production of heat by bacteria, using both the direct and the indirect methods. Bayne-Jones ('29) and Bayne-Jones and Rhees ( '29) have summarized the results obtained by those investigators who, following the way pointed out by Rubner, have studied the production of heat by bacteria.
Bayne-Jones ( '29) described a modification of the differential micro-calorimeter of Hill ( '11-'12) allowing the sterilization of the apparatus and the maintenance of a pure culture during the course of an experiment. Bayne-Jones and Rhees ('29) reporting the relation of heat production to the phases of growth of bacteria, were the first to enumerate the number of cells present a t given time intervals and thus obtain suffi- cient data for the analysis of heat production in relation to 'Based on portions of a thesis submitted by Clarence F. Schmidt, Jr., to the Faculty of the Graduate School of the University of Rochester in partial fulfillment of requirements for the degree of Doctor of Philosophy.
