Overview / Applications

Outline	This product consists of polysaccharides produced by Pseudomonas elodea, deacetylated and purified, and glucose, rhamnose and uronic acid are its active component.[Merits]1. It offers clear solid medium after gelling due to a higher clarity than agar allowing easy observation inside the medium.2. Soluble salts are required for gelling. Therefore, preparation of gels of various hardness is available by selecting the type of salt and amount of its addition as well as the amount of gellan gum used.3. A smaller amount of gellan gum offers gel strength equal to agar.4. It can accelerate growth rate of plant bodies.5. It is heat-resistant, not solating at high temperatures, allowing autoclave sterilization several times.6. Similarly to agar, it melts by heating (90 degrees C minimum) and gelates by cooling (30 to 50 degrees C maximum). This is a dried powder of polysaccharides produced extracellularly by Pseudomonas elodea, deacetylated and purified, and it is used as a gelling agent replacing agar in the culture media for plant tissues and microorganisms. It becomes a transparent gel at a lower concentration of 0.2 to 0.4 % as compared to agar and is said to offer good callus growth.
