Toward ultracentrifugation-free processing and long-term preservation of outer membrane vesicles by culture optimization, tangential flow filtration, diafiltration, and lyophilization

Outer membrane vesicles (OMVs) are bacterial membrane nanoparticles with applications in host–microbe interaction studies, vaccines, molecular delivery, and microbial biotechnology. However, OMV workflows often rely on ultracentrifugation, limiting accessibility and process integration. Here, we evaluated a laboratory-...

Participation of the Transcriptional Regulator Fur in Modulating Biofilm Formation of the Salmonid Pathogen Yersinia ruckeri: Beyond Iron Homeostasis

Fur is identified as an important contributor to the normal progression toward mature and spatially organized Y. ruckeri biofilms and the Fur-dependent pathways and factors identified here provide candidates for future mechanistic studies and may ultimately help identify strategies to interfere with Y. ruckeri persiste...
