Low Acyl Gellan Gum

  • This Low Acyl Gellan Gum is designed for use in microbiological and tissue culture media. This water-soluble, biopolymer, which is in the form of a white powder, is used as a gelling agent. It forms a hard gel at low concentrations in the presence of an electrolyte.

    Appearance: White powder

    Easy to disperse in water

    Low viscosity

    Forms a gel that doesn’t melt at high temperatures

    Gellan Gum content (%): 85.0—108.0

  • Low Acyl Gellan Gum Applications in Biotechnology Industry

    Low Acyl Gellan Gum can be used as an alternative to agar for microbiological media and as a bacterial growth media. It is also an ideal medium for plant tissue cultivation. It is particularly useful for the culture of thermophilic microorganisms, as the gels are thermostable and can withstand prolonged incubations at high temperatures. In addition, acceptable gel strengths can be obtained using gellan gum at a lower level than agar, and spreader colonies do not become too large. In these microbiological media applications, the high purity of Low Acyl Gellan Gum and the water-like clarity of the gels are distinct additional advantages.

    In plant tissue culture, Low Acyl Gellan Gum offers a promising alternative to agar because of its purity. Low Acyl Gellan Gum used at one-fifth the agar use level, resists contamination by moulds, is easily washed from the plant tissue for transplanting, and allows clear observation of root and tissue development.
