Metal homeostasis is fundamental for optimal performance of cell metabolic pathways. Over the course evolution, several systems emerged to warrant an intracellular metal equilibrium. When exposed growth-challenging copper concentrations, Gram-negative bacteria quickly activate copper-detoxification mechanisms, dependent on transmembrane-protein complexes and metallochaperones that mediate efflux. Here, we show vesiculation also a common bacterial response mechanism high extracellular...
Summary Aquaculture has been one of the fastest‐growing food industry sectors, expanding at pace consumers' demands. To promote safe and effective fish growth performance strategies, to stimulate environmentally friendly solutions protect against disease outbreaks, new approaches are needed safeguard welfare, as well farmers consumers interests. Here, we tested use cyanobacterial extracellular vesicles (EVs) a novel nanocarrier system heterologous proteins for applications in fish. We...
Cyanobacteria are a diverse group of photosynthetic, Gram-negative bacteria that play critical roles in global ecosystems and serve as essential biotechnology models. Recent work has demonstrated both marine freshwater cyanobacteria produce extracellular vesicles - small membrane-bound structures released from the outer surface microbes. While likely contribute to biological processes, their specific functional cyanobacterial biology remain largely unknown. To encourage advance research this...
Hospital-acquired infections are still a major concern worldwide, being frequently related to bacterial biofilm formation on medical devices, and thus difficult eradicate with conventional antimicrobial treatments. Therefore, infection-preventive solutions based natural polymers investigated. Recently, marine cyanobacterium-derived polymeric coating (CyanoCoating) has demonstrated great anti-adhesive potential when immobilized onto gold model substrates. In this work, we took technology step...
Disease outbreaks are a common problem in aquaculture, with serious economic consequences to the sector. Some of most important bacterial diseases affecting aquaculture caused by Gram-negative bacteria including Vibrio spp. (vibriosis), Photobacterium damselae (photobacteriosis), Aeromonas (furunculosis; haemorrhagic septicaemia) or Tenacibaculum maritimum (tenacibaculosis). Lipopolysaccharides (LPS) components outer membrane and have been linked strong immunogenic responses terrestrial...
Cyanobacteria are a group of photosynthetic prokaryotes that contribute to primary production on global scale. These microorganisms release vesicles the extracellular environment, spherical nanosized structures, derived essentially from outer membrane. Even though earlier works in model Gram-negative bacteria have hypothesized membrane stability is crucial vesicle formation, mechanisms determining biogenesis cyanobacteria remain unknown. Here, we report identification six candidate genes...
