A flavin-based extracellular electron transfer mechanism in diverse gram-positive bacteria
Extracellular electron transfer (EET) describes microbial bioelectrochemical processes in which electrons are transferred from the cytosol to the exterior of the cell1.

Destabilization of α-helical structure in solution improves bactericidal activity of antimicrobial peptides: Opposing effects on bacterial and viral targets [PDF]
We have previously examined the mechanism of antimicrobial peptides on the outer membrane of vaccinia virus. Here we show that the formulation of peptides LL37 and magainin-2B amide in polysorbate 20 (Tween-20™) results in greater reductions in virus ...

Bioactive Products From Plant-Endophytic Gram-Positive Bacteria
Endophytes constitute plant-colonizing microorganisms in a mutualistic symbiosis relationship. They are found in most ecosystems reducing plant crops’ biotic and abiotic stressors by stimulating immune responses, excluding plant pathogens by niche ...

Bacteria colonies modify their shear and compressive mechanical properties in response to different growth substrates [PDF]
Bacteria build multicellular communities termed biofilms, which are often encased in a self-secreted extracellular matrix that gives the community mechanical strength and protection against harsh chemicals. How bacteria assemble distinct multicellular structures in response to different environmental conditions remains incompletely understood. Here, we

Effect of motility on the transport of bacteria populations through a porous medium [PDF]
The role of activity on the hydrodynamic dispersion of bacteria in a model porous medium is studied by tracking thousands of bacteria in a microfluidic chip containing randomly placed pillars. We first evaluate the spreading dynamics of two populations of motile and non-motile bacteria injected at different flow rates.

In-vitro analysis of potential antibacterial activity of three medicinal plants [PDF]
The present study was aimed to examine and compare the antibacterial activity of hot methanolic extract of medicinal plants viz. Portulaca oleracea (purslane), Syzygium cumini (L.) (jamun), Psidium guajava (L.) (guava). Antibacterial activity was carried

The Tat system of Gram-positive bacteria
The twin-arginine protein translocation (Tat) system has a unique ability to translocate folded and co-factor-containing proteins across lipid bilayers. The Tat pathway is present in bacteria, archaea and in the thylakoid membranes of chloroplasts and, depending on the organism and environmental conditions, it can be deemed important for cell survival,
