2. Acinetobacter baylyi - Wikipedia

   en.wikipedia.org/wiki/Acinetobacter_baylyi

   Acinetobacter baylyi is a nonmotile, gram-negative coccobacillus. It grows under strictly aerobic conditions, is catalase -positive, nitrate-negative, oxidase-negative, and non-fermentative. [ 5 ] [ 6 ] The species is naturally competent , meaning the bacteria can take up exogenous DNA from their surroundings.

3. Crystal violet - Wikipedia

   en.wikipedia.org/wiki/Crystal_violet

   The stain proved popular and in 1884 was used by Hans Christian Gram to stain bacteria. He credited Paul Ehrlich for the aniline-gentian violet mixture. [32] Grübler's gentian violet was probably very similar, if not identical, to Lauth's methyl violet, which had been used as a stain by Victor André Cornil in 1875. [33]

4. Gram stain - Wikipedia

   en.wikipedia.org/wiki/Gram_stain

   A Gram stain of mixed Staphylococcus aureus (S. aureus ATCC 25923, gram-positive cocci, in purple) and Escherichia coli (E. coli ATCC 11775, gram-negative bacilli, in red), the most common Gram stain reference bacteria. Gram stain (Gram staining or Gram's method), is a method of staining used to classify bacterial species into two large groups ...

5. Methyl violet - Wikipedia

   en.wikipedia.org/wiki/Methyl_violet

   It is known in medicine as Gentian violet (or crystal violet or pyoctanin(e) [1]) and is the active ingredient in a Gram stain, used to classify bacteria. It is used as a pH indicator, with a range between 0 and 1.6. The protonated form (found in acidic conditions) is yellow, turning blue-violet above pH levels of 1.6. [4]

6. Gram-positive bacteria - Wikipedia

   en.wikipedia.org/wiki/Gram-positive_bacteria

   Both gram-positive and gram-negative bacteria commonly have a surface layer called an S-layer. In gram-positive bacteria, the S-layer is attached to the peptidoglycan layer. Gram-negative bacteria's S-layer is attached directly to the outer membrane. Specific to gram-positive bacteria is the presence of teichoic acids in the cell wall. Some of ...

7. Cell envelope - Wikipedia

   en.wikipedia.org/wiki/Cell_envelope

   The Gram-positive cell wall is characterized 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 Actinomycetota (or high %G+C Gram-positive organisms) and the Bacillota (or low %G+C Gram ...
