Dimensions of Escherichia coli at various growth rates: model for envelope growth.

The duplication of Escherichia coli B/r is described based on two independent sequences, the replication of the genome and the growth of the envelope. It is proposed that (i) new envelope growth zones are activated coincident with the initiation of new rounds of chromosome replication; (ii) each zone is active in envelope synthesis from the time of its inauguration to the division which follows...

Alteration of phospholipid at various growth phases of Escherichia coli.

By inoculating E. coli B into the semisynthetic medium we conducted shaking culture, and observed alterations of the total phospholipid contents and the amounts of individual phospholipid components in various stages of growth. The results are briefly summarized as follows. 1. The total phospholipid content has been found to be greater during early culture period, while it decreases as the grow...

Ribosome patterns in Escherichia coli growing at various rates.

The distribution of ribosomes, 30 and 50S subunits and polysomes, at three different growth rates of Escherichia coli strains B and K-12 has been studied. The usual percentage of subunits is about 20%. However, at the lowest growth rate (mu = generations/hour), mu = 0.45 at 30C, the proportion of subunits is about 30%. An exceptional situation exists in K-12 strains growing at maximum growth ra...

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 ...

A new logistic model for Escherichia coli growth at constant and dynamic temperatures

A new logistic model for bacterial growth was developed in this study. The model, which is based on the logistic model, contains an additional term for expression of the very low rate of growth during a lag phase, in its differential equation. The model successfully described sigmoidal growth curves of Escherichia coli at various initial cell concentrations and constant temperatures. The model ...
