PGPR Isolated from rhizospheric soil of Zanthoxylum armatum DC. in Garhwal Himalaya

Author(s): Nidhi Srivastava, Vineeta Bhandari and A.B. Bhatt
Abstract: The goal of this report was the identification of PGPR fromZanthoxylum armatum DC. A total of 11 genera were identified from rhizosphere of Z. armatum. A total of 32 isolates produced Indole acetic acid ranging from 0.69 µg/ml to 28.21 µg/ml, highest IAA being produced byPseudomonas sp. A total of 28 (63.63%) bacterial isolates produced ammonia. Qualitatively, 21 (47.72%) isolates belonging to the Pseudomonas sp., Bacillussp., Flavobacterium sp., Klebsiella sp., Enterobacter sp., Serratia sp. andAzotobacter sp genera displayed positive results towards phosphate solubilization and only 20 (45.45%) isolates exhibited positive results of siderophore production on CAS agar medium. The present study hence, provides a potential biofertilizer however, field studies of this isolate as soil inoculants in Z. armatum DC. are required in order to establish its actual performance.
