Gellan Gum Powder

High Transparency Microbiological Gel Media

Gellan gum 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 culture work and is a substitute for agar. Gels produced with gellan gum are clearer in comparison to agar; however, the gel can be 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.
