Why is Pikovskaya medium used?

Why is Pikovskaya medium used?

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.

Which bacteria is responsible for phosphate solubilization?

Diversity of Phosphate Solubilizing Microorganisms Among these PSMs, strains from bacterial genera (Bacillus, Pseudomonas, and Rhizobium), fungal genera (Penicillium and Aspergillus), actinomycetes, and arbuscular mycorrhizal (AM) are notable (Table 1).

How do you identify phosphate solubilizing bacteria?

For P-solubilizing ability determination, the isolates were screened by culturing at 28°C on the media supplemented either lecithin (Po culture medium) or Ca3(PO4)2 (Pi culture medium). When the colonies appeared in 4–5 days, those causing a clear phosphate-solubilizing zone were selected out for further calculation.

What are phosphate solubilising fungi and why are they important?

Phosphate-solubilizing fungi (PSF) play an important role in increasing the bioavailability of phosphorus in soils for plants. Thirteen fungal strains, one collected from air and 12 from soil, were screened and described here in detail.

What is Pikovskaya medium?

Pikovskaya’s Broth is a modification of Pikovskayas agar medium originally modified by Sundara Rao and Sinha (1) for culturing phosphate solubilizing microorganisms. Both inorganic and organic phosphates exists in soil.

What is PSB fertilizer?

PSB can be used for all crops including paddy, millets, oilseeds, pulses and vegetables. Methods recommended for application are: ☛ Seed treatment ☛ Seedling dipping ☛ Soil application Seed treatment: Same as described for Rhizobium.

How do you use PSB bacteria for plants?

The use of PSB as inoculants increases P uptake by plants. Simple inoculation of seeds with PSB gives crop yield responses equivalent to 30 kg P2O5 /ha or 50 percent of the need for phosphatic fertilizers. Alternatively, PSB can be applied through fertigation or in hydroponic operations.

How do you use phosphate solubilizing bacteria?

What is PSB Biofertilizer?

What is phosphate mobilization?

Phosphate mobilizing microorganisms are the microbes that participate in the mobilization of phosphorus in the soil. The majority of phosphate mobilizing microbes are phosphate solubilizing microorganisms. They release phosphorus from the insoluble and fixed forms of phosphorus in the soil.

Is PSB good for aquarium?

PSB helps improves the quality of water in an aquarium. It helps decompose many toxic matters such as nitrous acid, organic materials, ammonia, pond sludge, and hydrogen sulphide. It enhances the disease resistance capacity of an aquarium.

What is PSB Fertiliser?

PSB can be used for all crops including paddy, millets, oilseeds, pulses and vegetables.

What is significance of phosphate solubilizing bacteria in soil fertility?

Phosphate solubilizing bacteria (PSB) are the main contributors of plant nutrition in agriculture and could play a pivotal role in making soluble phosphorus available to plants (Khan et al., 2010). From: Beneficial Microbes in Agro-Ecology, 2020.
