Description
Pikovskaya’s Agar is recommended for detection of phosphate solubilizing soil microorganisms.
Yeast extract in the medium provides nitrogen and other nutrients necessary to support bacterial growth.
Dextrose acts as an energy source. Different salts and yeast extract supports the growth of organisms.
Phosphate-solubilizing bacteria will grow on this media and form a clear zone around the colony, formed due to phosphate solubilization in the vicinity of the colony.
Aspergillus brasiliensis, Pencillium notatum and Pseudomonas aeruginosa shows positive reaction, clear zone surrounding the colony.
