Gellan Gum CAS 71010-52-1

Gellan gum tissue is a water-soluble anionic polysaccharide generated by Sphingomonas Elodea (formerly referred to as Pseudomonas Elodea according to the taxonomic category at the time of its discovery). In 1978, the former kelco department of Merck discovered and separated microorganisms generating gellan periodontal from lily plant tissue in a natural fish pond in Pennsylvania. It is made use of to change agar as a strong coagulant to dramatically lower the growth level of numerous bacteria. Its original industrial item, gelrite gellan periodontal, was later identified as an ideal agar replacement as a gelling agent in numerous clinical bacteriological media.

Gellan gum was originally made use of as a gelling representative in microbial culture instead of agar. It can hold up against a high temperature of 120 ° C. It has been identified as an especially helpful gelling representative in the society of thermophilic bacteria. Only about fifty percent of gellan periodontal can be used as agar to accomplish the very same gel strength, although the precise appearance and also top quality depend upon the focus of both valent cations. Gellan periodontal is also made use of as a gelling representative in plant cell culture, due to the fact that it gives an extremely clear gel to help with the evaluation and organization of cells by optical microscopy. Although marketed as inert, experiments on bryophytes have revealed that the selection of gelling agent (agar or gelrite) does influence the phytohormone level of sensitivity of plant cell societies.
