gram-negative bacteria
Gram-negative bacteria have a thin cell wall with a single-layered murein. They therefore absorb no dye during Gram staining, and appear reddish under the microscope. Gram-negative bacteria are primarily rod bacteria and are endotoxic. Well-known members of this family are Legionella, the pseudomonads, and Borrelia.
-
gram-positive bacteria
Gram-positive Bakterien färben sich bei der Gramfärbung dunkelblau. Ursache ist eine dicke Zellwand mit mehrschichtigem Murein, welches bis zu 50% der Hüllentrockenmasse ausmachen kann. Grampositive Bakterien kommen hauptsächlich als Kokken vor und sie wirken exotoxisch. Beispiele: Listerien, Clostridien, Streptokokken und Staphylokokken.

gram staining
Developed by the Danish bacteriologist Hans Christian Gram, Gram staining is a method for rendering bacteria more visible under the microscope with the aid of a special dye. Depending on differences in their cell-wall structures, bacteria can basically be divided into two groups: Gram-positive and Gram-negative bacteria.
-
guanine
Guanine (C5H5N5O) is one of the four coding nucleobases of DNA and RNA. Guanine always base-pairs with the complementary cytosine, forming three hydrogen bonds with the latter.
