We have found the following scenario for a typical evolutionary run of our model: A population of cells that starts out ill-adapted goes through a phase of fast adaptation that is initially accompanied by a large increase in genome size and that is generally followed by rounds of adaptive gene loss.
After a rough phase of adaptation, I was overwhelmed with the cordiality that surged up on me.
It was found that the likelihood of this happening was much reduced is only the fundamental component of the harmonic controller was adapted initially, and then the other harmonics were changed in a second phase of adaptation.
This improvement, especially with respect to reduced diauxic lag during sugar transition, was further stabilized, and ethanol tolerance was enhanced and broadened by a second phase of adaptation in ethanol-challenged continuous culture.
Genome size and structure suggest that B. rhizoxinica is in an early phase of adaptation to the intracellular lifestyle (genome in transition).
The higher selective pressures suffered shortly after laboratory foundation could account for the initial lower effective sizes, since family contributions may vary greatly under strong selection in an initial phase of adaptation [ 6].
The cells were cultivated in a 3.6-L Infors HT-Labfors bioreactor in two stages, an initial batch phase in minimal medium, followed by a fed-batch phase of adaptation in a medium of liquid fraction with minimal medium.
In our case, the phase of adaptation to a new host would represent an epoch of strong selection and hence rapid phenotypic innovation.
As mentioned above, the systematic target perturbation of the adaptation paradigm triggers corrective saccades, at least during the initial phase of adaptation time-course.
After materials related to intervention content and process were initially developed based on focus group results, the second phase of adaptation, expert review, took place.
