TLDR
Bacterial growth is considered as a method for the study of bacterial physiology and biochemistry, with the interpretation of quantitative data referring to bacterial growth limited to populations considered genetically homogeneous.Abstract:
The study of the growth of bacterial cultures does not constitute a specialized subject or branch of research: it is the basic method of Microbiology. It would be a foolish enterprise, and doomed to failure, to attempt reviewing briefly a \"subject\" which covers actually our whole discipline. Unless, of course, we considered the formal laws of growth for their own sake, an approach which has repeatedly proved sterile. In the present review we shall consider bacterial growth as a method for the study of bacterial physiology and biochemistry. More precisely, we shall concern ourselves with the quantitative aspects of the method, with the interpretation of quantitative data referring to bacterial growth. Furthermore, we shall considerz exclusively the positive phases of growth, since the study of bacterial \"death,\" i.e., of the negative phases of growth, involves distinct problems and methods. The discussion will be limited to populations considered genetically homogeneous. The problems of mutation and selection in growing cultures have been excellently dealt with in recent review articles by Delbriick (1) and Luria (2). No attempt is made at reviewing the literature on a subject which, as we have just seen, is not really a subject at all. The papers and results quoted have been selected as illustrations of the points discussed.read more

TL;DR: A phenomenological study is described that reveals intrinsic constraints governing the allocation of resources toward protein synthesis and other aspects of cell growth, and may facilitate the understanding and manipulation of complex biological systems before underlying regulatory circuits are elucidated.

TL;DR: The precision and sensitivity of the manometric technique make it ideal for studying adaptation to nonvolatile compounds, but complications arise when such substances as benzaldehyde are tested, and the results cannot be strictly compared to those obtained with the remaining aromatic compounds investigated.

C. D. Kelly,Otto Rahn +1 more
TL;DR: In this article, it was shown that during the period of rapid growth, in a satisfactory culture medium, some bacteria will die in spite of good food and favorable environment, and this assumption was derived from an analogy with populations of higher forms of life, of which a number of individuals are known to die before they reach the reproductive age even with good care.

The Proportion of Viable Bacteria in Young Cultures with Especial Reference to the Technique Employed in Counting
TL;DR: During the course of some work on the morphological changes occurring during the life history of certain bacteria, it became desirable to ascertain the true relationship existing between the number of living organisms and the total number of cells in a young broth culture.
