Stationary phase is the stage when growth ceases but cells remain metabolically active.
Several physical and molecular changes take place during this stage that makes them …

Oxidative stress is strongly implicated in a number of diseases, such as rheumatoid arthritis,
inflammatory bowel disorders, and atherosclerosis, and its emerging as one of the most …

Bacteria are nutritionally starved most of the time and maintain fast growth rates during
availability, surviving prolonged periods of starvation as a result of elaborate physiological …

During carbon‐starvation‐induced entry into stationary phase, Escherichia coli cells exhibit
a variety of physiological and morphological changes that ensure survival during periods of …

Abstract Iron–sulfur (Fe–S) clusters are ancient, ubiquitous cofactors composed of iron and
inorganic sulfur. The combination of the chemical reactivity of iron and sulfur, together with …

Bacteria cope with many environmental challenges by activating coregulated groups of
genes in so-called global responses, which affect diverse cellular functions. This ability …

It is now well established that the σS subunit of RNA polymerase is a master regulator in a
complex regulatory network that governs the expression of many stationary‐phase …

The novel sigma factor (sigma S) encoded by rpoS (katF) is required for induction of many
growth phase-regulated genes and expression of a variety of stationary-phase phenotypes …

A remarkable feature of bacterial species is their capacity for rapid growth when nutrients
are available and conditions are appropriate for growth. Perhaps even more remarkable is …
