Enterococci are common, commensal members of gut communities in mammals and birds,
yet they are also opportunistic pathogens that cause millions of human and animal infections …

The capacity of bacteria to survive and grow at alkaline pH values is of widespread
importance in the epidemiology of pathogenic bacteria, in remediation and industrial …

The σS (RpoS) subunit of RNA polymerase is the master regulator of the general stress
response in Escherichia coli and related bacteria. While rapidly growing cells contain very …

Environmental fluctuations lead to a rapid adjustment of the physiology of Escherichia coli,
necessitating changes on every level of the underlying cellular and molecular network. Thus …

The σS (or RpoS) subunit of RNA polymerase is the master regulator of the general stress
response in Escherichia coli. While nearly absent in rapidly growing cells, σS is strongly …

Environmental stress and food preservation methods (eg, heating, chilling, acidity, and
alkalinity) are known to induce adaptive responses within the bacterial cell. Microorganisms …

Bacterial sigma (σ) factors are an essential component of RNA polymerase and determine
promoter selectivity. The substitution of one σ factor for another can redirect some or all of …

Microbial adaptation to environmental stimuli is essential for survival. While several of these
stimuli have been studied in detail, recent studies have demonstrated an important role for a …

Small non-coding RNAs with important regulatory roles are not confined to eukaryotes.
Recent studies have led to the identification of numerous small regulatory RNAs in …

Escherichia coli responds to oxidative stress by activating sets of coregulated genes that
help the cell to maintain homeostasis. Identified previously by genetic and biochemical …
