Abstract
Deficits in phosphate can hinder plant growth and development because it is essential
to all aspects of plant growth and development. The present study focused on isolation
and evaluation of soil bacterial isolated from 4 different locations. The 21 isolates
recovered were subjected to phosphate solubilization and siderophore productions
assay. As per the results 9 bacterial isolated (V1, V2, V3, V11, V12, V13, CV1,
CV2 and CV11) were found best phosphate solubilizers on the basis of qualitative
phosphate assay. Out of 9 screened bacterial isolated only 3 were best suited for
siderophore production (V2, V11 and V13). The pqq genes responsible for phosphate
solubilization were also checked through amplification and as per the observation,
5 bacterial isolates showed positive amplification (V1, V2, V3, V11, V13 and CV11).
The identified isolates present potential phosphate solubilizing ability of bacterial
isolates which can further be applied in the field of biofertilizer development
and commercialization.
