Extracellular matrix chemistry tunes bacterial biofilm metabolism and optimizes fitness

The paper shows how matrix chemistry in bacterial biofilms affects metabolism and fitness by modulating pyocyanin retention and electron transfer efficiency.

Starvation enhances bacterial survival through drying and rewetting at the single cell level

This study shows that pre-starvation enhances Pseudomonas synxantha's ability to survive desiccation by improving recovery from osmotic stress, despite reduced osmolyte synthesis.

Real-time high-resolution microscopy reveals how single-cell lysis shapes biofilm matrix morphogenesis

The paper uses real-time microscopy to show that single-cell lysis in Pseudomonas aeruginosa biofilms is spatially restricted and driven by nutrient gradients, shaping eDNA matrix morphogenesis.

SpoIIE drives asymmetric cell division in B. subtilis by sequential modulation of the cytokinesis machinery

This study shows SpoIIE modulates cytokinesis machinery in B. subtilis to drive asymmetric cell division by interacting with MinCD and DivIB, and regulating FtsZ filament length.

Designing efficient genetic code expansion in Bacillus subtilis to gain biological insights

This paper demonstrates efficient genetic code expansion in Bacillus subtilis using non-standard amino acids to enable chemical biology tools for studying bacterial biology.
