Bacterial extracellular vesicles (EVs) are known to mediate intercellular communication, virulence, and immune modulation. Here we show that bacteria can utilise EVs also as recyclable nutrient reservoirs. Using Bacillus cereus as a model organism, we demonstrate that EVs exhibit distin...

Gastrointestinal bacteria interact with the host and each other through various mechanisms, including the production of extracellular vesicles (EVs). However, the composition and potential roles of EVs released by gut archaea are poorly understood. Here, we study EVs produced by four strains of h...

Microbiota-released extracellular vesicles (MEVs) have emerged as a key player in intercellular signaling. However, their involvement in the gut-brain axis has been poorly investigated. In this study, we aimed to investigate the cargo capacity of MEVs for bioactive metabolites and their interacti...

Microbial driven manganese (Mn) reduction influences the geochemical cycling of Mn and the environmental fate of various organic and inorganic substances. Extracellular vesicles (EVs) are known to impact microbial metabolic activities, but their specific role in Mn reduction remains arcane. Here,...

Background Probiotics have attracted considerable interest for ulcerative colitis (UC); however, their efficacy is highly strain-specific and the underlying molecular mechanisms remain incompletely understood.

Results Accumulating evidence indicates that bacterial extracellular vesicles (BE...

Bacteroides thetaiotaomicron (Bt), a key commensal of the human gut microbiota, exhibits robust capacity to degrade dietary polysaccharides via carbohydrate-active enzymes (CAZymes). However, the exact spatial distribution and the functional coordination of these enzymes remain poor...

BACKGROUND: Ochratoxin A (OTA) have made it a serious hazard to food safety worldwide that poses a serious health risk to humans. Our previous research showed that Walnut green husk polysaccharides (WGP) can effectively alleviate intestinal inflammation and intestinal microbiota ...

Extracellular membrane vesicles (EMVs) are produced by many Gram-positive organisms, but information regarding vesiculogenesis is incomplete. We used single gene deletions to evaluate the impacts on Streptococcus mutans EMV biogenesis of Sortase A (SrtA), which affects S. mutans...

18 Bacteroidetes isoaltes were analyzed for their neuroactive potentail using un-targeted and targeted metabolomics. The bacteria were grown to stationary phase, the supernatant was separated and purified using 0.22 um filter. The metabolome from the supernatant was extracted using standard Metha...
