General description

Agar or Agar-agar is one of the major components found in the cell wall of red algae. It is a polysaccharide complex, comprising about 70% agarose and 30% agaropectin.

Application

Washed agar has been used:
  • as a supplement (0.9% w/v) to Murashige and Skoog basal medium for plant growth
  • in the preparation of cocultivation medium for Agrobacterium tumefaciens mediated transformation in maize (Zea mays) hybrid Hi-II
  • as a component in the complete medium to regenerate protoplasts of Piriformospora indica
  • as a clean agar medium to culture Synechococcus WH7803 strain

Biochem/physiol Actions

Agar is an ester of sulfuric acid in a linear galactan form, that makes it soluble in hot water and insoluble in cold. Washed agar contain less impurities and low level of nutrients.

Water is arguably the most important constituent of microbial microhabitats due to its control of physical and physiological processes critical to microbial activity. In natural environments, bacteria often live on unsaturated surfaces, in thin (micrometric) liquid films. Nevertheless, no experimental
