 ABSTRACT

In present investigation isolation and characterization of native Providencia vermicola was attempted form rhizospheric soil of sickplot, Model farm, AAU, Vadodara, Gujarat. From the overall morphological, biochemical and 16S rDNA sequencings, the isolate was identified and designated as Pr. vermicola AAU PR1. The isolate showed positive PGPR traits viz. phosphate solubilisation, potash solubilisation, IAA production and ACC deaminase production. Moreover, the isolate also showed inhibition of hatching of M. incognita eggs after 24, 48 and 72 hrs. of exposure. The isolate was also showed inhibition of multiple fungal pathogens viz. A. alternate (ITCC-5503), A. alternate (ITCC-6134), A. alternate (ITCC-7067), A. niger (ITCC-6202), A. niger (ITCC-6738), M. phaseolina (ITCC-6734), M. phaseolina (ITCC-6749), P. aphanidermatum (ITCC-5488), F. solani (ITCC-6846), F. udum, F. oxysporum. The mechanism behind the biocontrol potential of the strain includes its ability to produce siderophores, cell wall degrading enzymes viz. and cellulose, chitinase and lipase as well as volatile compound hydrogen cyanide. To the best of our knowledge this is the first time report wherein both biocontrol and plant growth promoting traits were found positive a strain of Pr. Vermicola.

Keywords: Providencia vermicola, PGPR, Meloidogyne incognita, biocontrol, chitinase, hydrogen cyanide.
