ABSTRACT

 

Rhizospheric bacteria are known to be effective for plant growth by direct and indirect mechanisms. Oxalate metabolizing bacteria have the great interest for the phytopathogenic fungal inhibition and kidney stone management purposes. A total of 27 oxalotrophic phosphate solubilizing bacteria were isolated from rhizosphere soil of oxalogenic plant. These isolates were studied for their plant growth promoting factors like indole acetic acid production , cell wall degrading enzyme activities, cellulase, chitinase and proteolytic enzyme. The results showed that rhizospheric oxalate utilizing bacteria could be a promising source for plant growth promoting agent in agriculture.
