Total eighteen bacteria were isolated using different nutrient media from rhizospheric soil of medicinal plants viz. Safed musli (Chlorophytum borivillianum), Shankh pushpi (Convolvulus pluricaulis) and Kalmegh (Andrographis paniculata) from Anand Agriculture University, Gujarat. The isolates were characterized morphologically and biochemically. Amongst all, three isolates A5, A7 and A18 proved to be the best for their plant growth promoting efficiency viz. solubilization/mobilization of insoluble phosphate and potash, production of siderophore, cellulase and ACC deaminase enzyme and growth hormone indole acetic acid (IAA) as well as showed inhibition of plant pathogenic fungi Macrophomina phaseolina and Aspergillus flavus by 27% to 55%, respectivelyenAgricultural MicrobiologyCharacterizationIsolation and characterization of rhizospheric bacteria from medicinal plants and their efficacy for plant growth promotion in Kalmegh (Andrographis paniculata)Thesis
