Evaluation of Rhizospheric Bacteria from Ocimum sp. as Potential Pgpr

Baljeet Singh Saharan and Shuchita Verma

In the present investigation, 24 rhizospheric soil samples of Ocimum sp. were collected from different vicinities of Delhi, Kurukshetra and Haridwar (India). A total of 266 bacterial strains were isolated and screened for in vitro plant growth promoting trait. About 86.46% bacterial isolates showed ammonium production, 89.09% exhibited phosphate solubilization and 87.59% for catalase production whereas only 7.14% showed positive reaction for HCN production. Five isolates viz., CHII(II)K7, CHIII(I)Y6, DDI(I)1, UHI(II)7 and CHII(I)NA4 were found to exhibit maximum number of plant growth promoting traits.
