What is Pikovskaya Agar?
What is Pikovskaya Agar? Pikovskayas Agar was modified by Sundara Rao and Sinha (2) for detection of phosphate-solubilizing bacteria from soil. Yeast extract in the medium provides nitrogen and other nutrients necessary to support bacterial growth. Dextrose acts as an energy source. Why is Pikovskaya medium used? Pikovskaya (1948) was the first person to develop a medium for the detection of PSB using calcium phosphate and dextrose based on the visual detection of clear zones. Furthermore, these authors recommended the use of rock phosphate for alkaline soils and iron phosphate and aluminum phosphate compounds for acidic soils. What is PSB...
