Differential impact of cell wall antibiotics on the Rod complex and aPBPs in Bacillus subtilis: Insights into the peptidoglycan elongation machineries
Charlène Cornilleau, Claire-Jing Rouchet, Aurélien Barbotin…·Rut Carballido‐López
This study examines how different cell wall antibiotics affect peptidoglycan synthesis in Bacillus subtilis, revealing distinct morphological outcomes and mechanisms of cell lysis.

Two temperature-dependent membrane fluidity regimes in Gram-positive bacteria
Aurélien Barbotin, Dimitri Juillot, Paprapach Wongdontree, Rut Carballido‐López
The paper measures membrane fluidity in Gram-positive bacteria across temperatures and finds fluidity is maintained at low temperatures but not at higher temperatures.

Transient inhibition of cell division in competent pneumococcal cells results from deceleration of the septal peptidoglycan complex
Dimitri Juillot, Cyrille Billaudeau, Isabelle Mortier‐Barrière…·Rut Carballido‐López
The paper investigates how ComM, a membrane protein in Streptococcus pneumoniae, transiently inhibits cell division during competence by reducing septal peptidoglycan synthesis.
