Microbial experimental evolution

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2009
Microbes have been widely used in experimental evolutionary studies because they possess a variety of valuable traits that facilitate large-scale experimentation. Many replicated populations can be cultured in the laboratory simultaneously along with appropriate controls.

Metabolic and microbial perspectives on the “evolution of evolution”

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, 2019
Abstract Identifying and theorizing major turning points in the history of life generates insights into not only world‐changing evolutionary events but also the processes that bring these events about. In his treatment of these issues, Bonner identifies the evolution of sex, multicellularity, and nervous systems as enabling the ...

An uncertainty law for microbial evolution

Journal of Theoretical Biology, 2020
Medical practice would benefit from a thorough understanding of constraints and uncertainty in microbial evolution. Higher order epistasis refers to unexpected effects of multiple mutations even if both single mutations and pairwise effects have been accounted for.

Elements in microbial evolution

Journal of Molecular Evolution, 1991
Spontaneous mutation, selection, and isolation are key elements in biological evolution. Molecular genetic approaches reveal a multitude of different mechanisms by which spontaneous mutants arise. Many of these mechanisms depend on enzymes, which often do not act fully at random on the DNA, although a large number of sites of action can be observed. Of

Structural Evolution in Microbial Polyesters

The Journal of Physical Chemistry B, 2008
The crystallization behavior of microbially synthesized poly(3-hydroxybutyrate) (PHB) and its copolymers [P(HB-co-HHx)] containing 2.5, 3.4, and 12 mol % 3-hydroxyhexanoate (HHx) comonomer and the melting of the resultant crystals were studied in detail using time-resolved small-angle X-ray scattering and differential scanning calorimetry.
