Optimizing the product of the wow factor and the beneficial mutation supply rate

This post follows up on my post from yesterday, which was about choosing a dilution factor in a microbial evolution experiment that avoids the loss of too many beneficial mutations during the transfer bottleneck. 274 more words

If

Every day, we propagate the E. coli populations in the long-term evolution experiment (LTEE) by transferring 0.1 ml of the previous day’s culture into 9.9 ml of fresh medium. 1,436 more words

Cue-Based Hedging

Usually a contrast is made between bet hedging and adaptive plasticity. What makes adaptive plasticity different from hedging is that organisms respond adaptively to environmental cues. 807 more words

Asking for a Skeptic Friend

I sometimes get email from people asking, in one way or another, whether our long-term evolution experiment (LTEE) with E. coli provides evidence of evolution writ large – new species, new information, or something of that sort. 421 more words

Paper out: No effect of natural transformation on the evolution of resistance to bacteriophages in the Acinetobacter baylyi model system

A long time coming, but the results obtained in NERC-funded research on evolutionary benefits (or lack thereof) of bacterial transformation have now been published. The work was carried out mainly by research tech… 298 more words

Colistin resistance evolution

The wide spread use of antibiotic has lead to evolution and spread of bacteria resistant to drugs. Multi-resistant strains tend to circulate in hospitals with a high density of people on antibiotic therapy. 704 more words
