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. Gellan gum melts 80°C to 100°C and gels at 10 to 50°C. Gellan Gum – Gel is clear and no synerisis or weeping. Gellan Gum is pH tolerant from 3 to 10. Plant gel gelation is promoted by calcium chloride (fused). 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.
