Aleksandrow agar consists of salts like magnesium sulphate, calcium carbonate, and potassium alumino silicate, ferric chloride which support the growth of potassium-solubilizing bacteria by providing the essential minerals.
Dextrose is a carbon and energy source. The potassium alumino silicates serve as an inorganic source of potassium salts. Potassium solubilizing bacteria utilize and solubilize potassium alumino silicates and form a clear zone around the colony.
Use:
Recommended for isolation and detection of potassium solubilizing bacteria from soil samples in agro and biofertilizer industries.
