General description

Bacteriological agar is a colloidal substance and a cell wall component, obtained from Rhodoyceae (marine algae) and Gelidium sp. Agarose combined with agaropectin forms this polysaccharide. It is also called as agar-agar and is a polymer of galactoside. This agar is soluble in boiling water but not in cold water.

Application

Bacteriological agar has been used:
  • as a component of ATCC agar for Escherichia coli culture
  • as one of the experimental diet feed for Atlantic salmon fry, to study the protein and lysine requirements for maintenance and for tissue accretion
  • as component of yeast extract peptone dextrose medium, Luria broth medium and synthetic complete drop out medium for Escherichia coli culture

Biochem/physiol Actions

Bacteriological agar is commonly used as a culture medium for microorganism. It is useful for fermentation process. Agar-agar serves as a preservative in food processing. It also possesses various other applications such as an emulsifier, carrier, lubricant, stabilizer, laxative disintegrant in pharmaceutical and cosmetic industries. Agar-agar is also used in photographic emulsion.

Quality

A purified agar in which the original naturally occurring pigments, salts and miscellaneous matter have been reduced to a minimum.
