Description

Descrição geral

Agar chemically consists of two fractions: agarose, a neutral polymer of high gel strength and agaropectin, a non-gelling fraction with sulfated β-1,3-glycosidically linked D-galactose units.

Agar is a hydrophilic colloid obtained from marine algae (Rhodophyceae). It is soluble in boiling water and is of significance to the microbiological area.

Aplicação

Agar has been used in the plant growth media.
Typical working concentration: 6-12g/L.

Agar has been used:

• as a reference standard commercial agar to compare the physio-chemical, gelling properties of alkali-treated agar from Gracilaria tenuistipitata
• as a component in the seed germination medium and rooting medium for commercially available soybean (Glycine max (L.) Merr) seeds
• as a component of growth media for B. subtilis mutant strain MTC871 based biofilm colonies
• as a bacteriological agar component to prepare half strength Murashige-Skoog (MS 50%) medium for Echinocactus platycanthus seeds culture

Ações bioquímicas/fisiológicas

Agar is gel forming polysaccharide used as a gelling and stabilizing agent. Its serves as a cryoprotectant in processed foods, pharmaceuticals and cosmetics products.
