What Is Gellan gum
Gellan gum is an almost white powder, odorless and tasteless substance. Its most important feature is that it can form a gel at a low concentration (0.05%). Generally, it is firstly dispersed in water (insoluble in cold water), heated to 75°C for hydration, then added with appropriate cationic chemical booklets, heated to 80-90°C, and forms a gel after cooling. The gel is reversible to heat, but if the type and concentration of cations are properly controlled, the gel can still maintain a gel state at a relatively high temperature (100°C).

Application
Biochemical research. Gelling agent. Phytagel is a substitute for agar secreted from Pseudomonas. It is a mixture of glucuronic acid, rhamnose and glucose. It is colorless, transparent and high-toughness. It is used to prepare plant Chemicalbook tissue culture medium and The main component of microbial culture medium. Because it overcomes the inherent defects of traditional agar in plant tissue culture and brings a new revolution to botany research, it has become an internationally recognized product of choice for plant tissue culture.
