Bacterial chemotaxis to saccharides is governed by a trade-off between sensing and uptake

N. Norris, U. Alcolombri, J. M. Keegstra, Y. Yawata, F. Menolascina, E. Frazzoli, N. M. Levine, V. I. Fernandez, R. Stocker

This paper shows E. coli limits maltose uptake via porins to enhance chemotactic sensitivity to micromolar maltose gradients despite having a high-affinity transport system.

Mechanistic model of nutrient uptake explains dichotomy between marine oligotrophic and copiotrophic bacteria

N. Norris, N. M. Levine, V. I. Fernandez, R. Stocker

The paper develops a mechanistic model showing that oligotrophic bacteria use binding proteins to achieve low KM values for nutrient uptake, despite their slow diffusion, which limits growth rates compared to copiotrophs.

Synthesis and degradation of FtsZ determines the first cell division in starved bacteria

K. Sekar, R. Rusconi, T. Fuhrer, E. Noor, J. Nguyen, V. I. Fernandez, M. F. Buffing, M. Berney, R. Stocker, U. Sauer

The paper shows that FtsZ synthesis and degradation determine the first division of starved bacteria in response to nutrient pulses.
