Growth rate of Escherichia coli

Fed-batch Cultivation of Recombinant Escherichia coli Producing Human Interferon-γ Under Controlled Specific Growth Rate

Response of Escherichia coli growth rate to osmotic shock.

It has long been proposed that turgor pressure plays an essential role during bacterial growth by driving mechanical expansion of the cell wall. This hypothesis is based on analogy to plant cells, for which this mechanism has been established, and on experiments in which the growth rate of bacterial cultures was observed to decrease as the osmolarity of the growth medium was increased. To disti...

Growth rate control of periplasmic product retention in Escherichia coli

The recombinant product is secreted to the periplasm in many processes where E. coli is used as host. One drawback with secretion is the undesired leakage of the periplasmic products to the medium. The aim of this work was to find strategies to influence the periplasmic retention of recombinant products. We have focused on the role of the specific growth rate, a parameter that is usually contro...

Bacteriophage T4 development in Escherichia coli is growth rate dependent.

Three independent parameters (eclipse and latent periods, and rate of ripening during the rise period) are essential and sufficient to describe bacteriophage development in its bacterial host. A general model to describe the classical "one-step growth" experiment [Rabinovitch et al. (1999a) J. Bacteriol.181, 1687-1683] allowed their calculations from experimental results obtained with T4 in Esc...

Robust Growth of Escherichia coli

The quantitative study of the cell growth has led to many fundamental insights in our understanding of a wide range of subjects, from the cell cycle to senescence. Of particular importance is the growth rate, whose constancy represents a physiological steady state of an organism. Recent studies, however, suggest that the rate of elongation during exponential growth of bacterial cells decreases ...
