In general the following characteristics are present in gram-positive bacteria: 1. Cytoplasmic lipid membrane 2. Thick peptidoglycan layer 3. Teichoic acids and lipoids are present forming lipoteichoic acids which serve as chelating agents and also for certain types of adherence. The gram-positive cell wall is characterised by the presence of a very thick peptidoglycan layer which is responsible for the retention of the crystal violet dyes during the Gram staining procedure. It is found exclusively in organisms belonging to the Actinobacteria (or high %G+C gram-positive organisms) and the Firmicutes (or low %G+C gram-positive organisms). Bacteria within the Deinococcus-Thermusgroup may also exhibit gram-positive staining behaviour but contain some cell wall structures typical of gram-negat… Penicillin molecules are small enough to pass through the spaces of glycoproteins in the cell wall. For this reason Gram-positive bacteria are very susceptible to penicillin (as first evidenced by the discovery of penicillin in 1928). Penicillin or any other molecule enters Gram-negative bacteria in a different manner. The bacteria have thinner cell walls but the external surface is coated with an additional cell … Cell envelope - Wikipedia Actinobacteria - Wikipedia Quorum sensing - Wikipedia Penicillin - Wikipedia Mon Dec 22 2003 13:30:00 GMT-0500 (Eastern Standard Time) · Crystal violet stains both Gram positive and Gram negative organisms. Treatment with alcohol removes the crystal violet colour from gram negative organisms only. Safranin as counterstain is used to colour the gram negative organisms that got decolorised by alcohol. While ex vivo many cells continue to live and metabolize until they are "fixed". Gram-positive pathogens. The spectrum of activity of the carbapenems against gram-positi...
