Longitudinal sampling of the stool has yielded important insights into the ecological dynamics of the human gut microbiome. However, human stool samples are available approximately once per day, while commensal population doubling times are likely on the

Fig: Different Types of Phases in Growth in Plants 1.Meristematic or formative phase or phase of cell divisionis the phase where active cell division takes place in the root apex, shoot apex, and other regions having meristematic tissue, thereby increasing the numbers. ...
…growth is followed by the stationary phase, in which the size of a population of bacteria remains constant, even though some cells continue to divide and others begin to die. The stationary phase is followed by the death phase, in which the death of cells in the population exceeds the…...
In the stationary phase, growth reaches a plateau as the number of dying cells equals the number of dividing cells. The death phase is characterized by an exponential decrease in the number of living cells. Bacteriarequire certain conditions for growth, and these conditions are not the same for...
Streptomyces are a genus of ubiquitous soil bacteria from which the majority of clinically utilized antibiotics derive1. The production of these antibacterial molecules reflects the relentless competition Streptomyces engage in with other bacteria,
For unicellular microorganisms (the majority of bacteria and yeasts), we use two measures of cellular abundance, the concentration of cell mass (x) and cell number (N). They are related to each other by a simple formula: [1]x=mN where conversion factor m is the average dry mass of a ...
Bacteria respond to changes in their environment with specific transcriptional programmes, but even within genetically identical populations these programmes are not homogenously expressed1. Such transcriptional heterogeneity between individual bacteria allows genetically clonal communities to develop a complex arra...
