Description

A high molecular weight polysaccharide gum produced by a pureculture fermentation of a carbohydrate with Pseudomonas elodea, and purified by recovery with isopropyl alcohol, dried, and milled. It is a heteropolysaccharide comprising a tetrasaccharide repeating unit of one rhamnose, one glucuronic acid, and two glucose units. The glucuronic acid is neutralized to mixed potassium, sodium, calcium, and magnesium salts. It may contain acyl (glyceryl and acetyl) groups as the O-glycosidically linked

Gellan gum Use and Manufacturing

Methods of Manufacturing

Pseudomonas elodea (ATCC 31461) was cultured in a liquid medium composed of glucose, corn syrup, phosphate, protein, nitrate and trace elements for 2 days. What is obtained at this time is a natural, high-acetyl gel cold glue, which has half an acetyl group and half a glyceric acid group on its glucose base. The presence of acetyl groups will seriously affect its gel properties, so It is necessary to add potassium hydroxide to the resulting mash to make it alkaline to remove the acetyl and glycerol groups to obtain low-acetyl clean cold gum. Then it is heated, filtered, and precipitated with isopropanol to obtain deacetylated clarified gellan gum.

Uses

Biochemical research. Gelling agent. Phytagel is a kind of agar substitute secreted from Pseudomonas. It is a mixture of glucuronic acid, rhamnose and glucose. It has the characteristics of colorlessness, transparency and high toughness. It is a plant tissue culture medium and microorganism. The main component of the culture medium. Because it overcomes the inherent defects of traditional agar in plant tissue culture, it brings a new revolution to botanical research and has become an internationally recognized product for plant tissue culture.

Material

Potassium hydroxide
