What type of bacteria has an lipopolysaccharide layer outside the peptidoglycan layer?
Gram-negative bacteria.
What is the function of LPS or Lipopolysaccharide?
The major component of the bacterial cell wall of Gram-negative bacteria is LPS, Lipopolysaccharide. LPS helps protect the membrane from certain kinds of chemical attack and greatly contributes to the structural integrity of the bacteria.
Why would bacteria stain gram variable?
A gram-negative cell will lose its outer membrane and the peptidoglycan layer is left exposed. or it is best to use younger cells ( 12-24hr) because older gram positive bacteria are subject to break down of the cell wall by enzymes that are produced with age which may result ingram variable staining.
What is another name for Lipopolysaccharide?
lps
Why does alcohol decolorize gram negative bacteria?
Gram Negatice bacteria contain a cell membrane made up of thinner peptidoglycan layer plus a lipopolysaccharide layer, unlike gram positves bacteria's thick peptidoglycan layer. Alcohol delcolourizes gram negative bacteria because it disrupts the lipopolysaccharide and the crystal violet-iodine complex is able to now pass through the thin layer of peptidoglycan left leaving no crystal violet colour in the gram negatice bacteria that can now take up the red/pink colour of the safranin introduced be the subsequent counterstaining procedure.
