CAS 71010-52-1 — Gelrite gellan gum

Gelrite gellan gum is a low-acyl (deacetylated), microbial-derived polysaccharide that forms firm, brittle, highly transparent gels and is widely used as a gelling agent in plant tissue culture and microbiological media. It replaces agar in many applications due to its superior performance at lower concentrations and broader pH tolerance. This non-toxic, neutral-tasting gum forms gels at concentrations as low as 0.04% without syneresis, even under refrigeration or freezing. It is soluble in hot water and resists degradation, making it ideal for sterile environments. Molekula supplies Gelrite gellan gum from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
