Bacteriological Agar - Type A & E
Bacteriological Agars act as solidification agents in the preparation of solid culture media at concentrations between 12 and 20 g / L. Bacteriological agar type A is an American type agar which presents a gel strength less than that of the type E European agar.
- Agar is comprised essentially of agaraose (70 %) and of agaropectin (30 %) which form together a solid gel after heating and cooling.
- Agarose is a linear polysaccharide entirely comprised of D-galactose and of 3-6 anhydro-L-galactose linked at alpha 1-3 and beta 1-4.
- Agaropectin, which is similar to that of agarose, also contains groups of anionic esters linked to calcium and to magnesium as well as organic acids (glucuronic and pyruvic).
- The 3-6 anhydro-α-L-galactoside link is very sensitive at low pH, so much so that it is necessary to avoid prolonged heating of acid media, which could lead to the depolymerization of the agar and consequently a loss of gel strength.
