Plant Gel (Gellan Gum) A.C.S. <90%

Plant Gel is the brand name for the Gellan Gum of Marine Hydrocolloids. Gellan Gum is a High Molecular weight (formula weight approximately 500,000) Poly saccharide gum produced by fermentation of a carbohydrate by pseudomonas Elodea, purified, dried and powdered.

Gellan Gum will disperse in cold water. Dispersion is aided by use of warm/hot water. Gellan gum can be used as a replacement for Agar Agar for many applications. Plant Gel can be used for making clear gel, with rigidity, thermal stability, compatible with natural additives. Hence ideal for preparation of nutrient media for most microbial application and plant tissue culture work.
