Layer-by-Layer (LbL) self-assembly encapsulation is a promising technology for the protection and delivery of lactic acid bacteria. However, laboratory-scale encapsulation is often time-consuming, involves intensive protocols tailored for small-scale operations, requires substantial amounts of energy and water, and results in a low yield of encapsulated biomass. Scaling-up this process to a bench-bioreactor scale is not simply a matter of increasing culture volume as different key parameters (not particularly relevant at lab scale) become critical, including biomass production, the number of polymer layers, and the biomass-to-polymer mass ratio.

Efflux pumps play crucial roles in mediating antimicrobial resistance, motility, and virulence. In this study, we present the identification and characterization of the new efflux pump SxtP belonging to the MFS superfamily (ajor acilitator uperfamily), along with its associated activator ysRtype ranscriptional egulator (LTTR) SxtR, demonstrating their roles in sulfamethoxazole/trimethoprim (also known as co-trimoxazole or SXT) resistance, surface-associated motility and virulence.

Our objective was to evaluate the frequency of VSS in PWM and to analyze if symptoms of VSS happened in a permanent or episodic manner (eVSS) in this population.
Methods: We conducted a multicenter observational cross-sectional study.
