Gram-negative bacteria are bacteria that, unlike gram-positive bacteria, do not retain the crystal violet stain used in the Gram staining method of bacterial...

The Gram stain is used by microbiologists to place bacteria into two main categories, Gram-positive (+) and Gram-negative (−). Gram-positive bacteria have...

threshold triggers altered gene expression. Performed by both Gram-negative and Gram-positive bacteria, detection of autoinducers allows them to sense one another...

reduced permeability in bacteria, the mechanisms are different between Gram-positive and Gram-negative bacteria. In Gram-positive bacteria, blockage of penicillin...

peripheral enzyme E1 is an alpha2beta2 heterotetramerin eukaryotes. In Gram-negative bacteria, e.g. Escherichia coli, PDC consists of a central cubic core made...

bacterial outer membrane called the periplasmic space in Gram-negative (more accurately "diderm") bacteria. Using cryo-electron microscopy it has been found...

80 species of bacteria were known to be capable of transformation, about evenly divided between Gram-positive and Gram-negative bacteria; the number might...

bacterial cell walls, those of Gram-positive bacteria and those of Gram-negative bacteria, which are differentiated by their Gram staining characteristics....

Both gram-positive and gram-negative bacteria use quorum sensing, but there are some major differences in their mechanisms. For the bacteria to use...

Atypical bacteria are bacteria that do not get colored by gram-staining but rather remain colorless: they are neither Gram-positive nor Gram-negative. These...

Poly(ethylenimine) is also an effective permeabilizer of the outer membrane of Gram-negative bacteria. Both linear and branched polyethylenimine have been used for CO2...
