Gellan gum (also known as Phytagel, Gelzan, Gelrite, or Applied gel) is a water soluble anionic polysaccharide produced by fermentation of a carbohydrate by pseudomonas Elodea, purified, dried, and powdered.

Gellan gum is ideal for preparation of nutrient media for in plant tissue culture work and is a substitute for agar. Gels produced with gellan gum are clearer in comparison to agar. However, the gel is more rigid and brittle than agar gel. Gellan gum requires roughly half the amount of agar that is needed. Gellan gum melts at 80°C– 100°C and gels between 10°C-50°C.

Gellan Gum is used as microbial solid culturing media. The substance is often used in doses ranging between 0.2% (2g/L) to 0.4% (4g/L) (w/v) to solidify plant tissue culture media. PPM can be mixed and autoclaved when creating Gellan Gum media.
