Conditions that sustain constant bacterial growth are seldom found in nature. Oligotrophic
environments and competition among microorganisms force bacteria to be able to adapt …

Oxidative stress, through the production of reactive oxygen species, is a natural
consequence of aerobic metabolism. Escherichia coli has several major regulators activated …

During evolution of biodegradation pathways for xenobiotic compounds involving Rieske
nonheme iron oxygenases, the transition toward novel substrates is frequently associated …

In a growth-restricting environment, mutants arise that are able to take over bacterial
populations by a process known as adaptive mutation or stationary-phase mutation. This …

The rate at which mutations are generated is central to the pace of evolution. Although this
rate is remarkably similar amongst all cellular organisms, bacterial strains with mutation …

Background Soil bacteria typically thrive in water-limited habitats that cause an inherent
matric stress to the cognate cells. Matric stress gives rise to accumulation of intracellular …

Under growth-restricting conditions bacterial populations can rapidly evolve by a process
known as stationary-phase mutagenesis. Bacterial nonhomologous end-joining (NHEJ) …

Nitrogen oxides (NO x) and chromium can cause harm to human health and ecological
environment. An aerobic denitrifying biotrickling filter (DBTF) for simultaneous removal of NO …

Aims To investigate how the growth stage of Enterococcus faecalis affects its
photoinactivation in clear water. Methods and Results Enterococcus faecalis were grown in …

Homologous recombination (HR) has a major impact in bacterial evolution. Most of the
knowledge about the mechanisms and control of HR in bacteria has been obtained in fast …
