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
