Description: Gellan Gum is a bacterial exopolysaccharide, prepared commercially by aerobic submerged fermentation from Sphingomonas elodea.
Soluble in water, it is used primarily as an alternative to agar as a gelling agent in microbiological culture.
Its largest advantages over agar are its almost perfect visual clarity and its strength; it is able to withstand 120 degree Celsius heat, making it especially useful in culturing thermophilic organisms.
One needs only approximately half the amount of gellan gum as agar to reach an equivalent gel strength, though the exact texture and quality depends on the concentration of divalent cat ions present.
