Isolation, characterization and screening of phosphate (P) solubilizing actinomycetes and exploring its potency in finger millet (Eleusine coracana L.).

ABSTRACT:

Background

Phosphorus (P) bioavailability, a major problem in acidic agro-ecosystem due to its fixation in clay lattices. Bioavailability of insoluble P is enhanced by phosphate solubilizing microorganisms (PSMs). Therefore, the current study was carried out to evaluate the phosphate solubilizing efficiency of isolated actinomycetes from different acid soils.

Methods

Isolation of actinomycetes from native soils and its potency was studied in a pot experiment with fourteen treatments, laid out in completely randomized design.

Results

A total of 54 actinomycetes strains were isolated out of which six strains showed the ability of P solubilization and tested positive for biochemical tests like urease, methyl red, ammonia production and decomposition of esculin, starch, c
