Chemotaxis allows bacteria to follow gradients of nutrients and other environmental stimuli.
The bacterium Escherichia coli performs chemotaxis via a run-and-tumble strategy in which …

To succeed, many cells must alternate between life-styles that permit rapid growth in the
presence of abundant nutrients and ones that enhance survival in the absence of those …

Optical density (OD) measurements of microbial growth are one of the most common
techniques used in microbiology, with applications ranging from studies of antibiotic efficacy …

Protein synthesis by ribosomes takes place on a linear substrate but at non-uniform speeds.
Transient pausing of ribosomes can affect a variety of co-translational processes, including …

ABSTRACT Luria-Bertani broth supports Escherichia coli growth to an optical density at 600
nm (OD600) of 7. Surprisingly, however, steady-state growth ceases at an OD600 of 0.3 …

Bacterial persisters are phenotypic variants that form from the action of stress response
pathways triggering toxin-mediated antibiotic tolerance. Although persisters form during …

Bacterial chemotaxis, the directed movement of cells along gradients of chemoattractants, is
among the best-characterized subjects in molecular biology,,,,,,,,–, but much less is known …

Escherichia coli DH10B was designed for the propagation of large insert DNA library clones.
It is used extensively, taking advantage of properties such as high DNA transformation …

We present a comprehensive overview of the hierarchical network of intracellular processes
revolving around central nitrogen metabolism in Escherichia coli. The hierarchy intertwines …

Biofuels are currently produced from carbohydrates and lipids in feedstock. Proteins, in
contrast, have not been used to synthesize fuels because of the difficulties of deaminating …
