Abstract:

Endophytic bacteria exhibit a complex web of interactions with host plants and have been extensively studied over the last several years as prolific sources of new bioactive natural products. The present study was conducted for isolation of endophytic bacterial population of Ocimum sanctum and Aloe vera and their evaluation for enzymatic activity and plant growth promotion. Morphological characteristics of the bacterial endophytes confirmed that all the bacterial isolates were either gram positive or gram negative rods and cocci. The biochemical study of the bacterial isolates confirmed their abilities to show extracellular enzymatic activity for urease, pectinase, cellulose, catalase, lipase, casienase, gelatinase and chitinase enzymes. Bacterial isolates were also able to show plant growth promoting traits like phosphate solubilization, IAA, siderophore and ammonia production. On the basis of plant growth promoting traits four potential bacterial endophytes were screened and further evaluated for their plant growth promotory (PGP) potential through seed vigour assay with green gram var. Pant Moong- 4. The results of the seedling vigour assay confirmed that bacterium AVJR7II showed highest influence on seed germination and subsequent seedling growth followed by TNR15, TKR2II and AVJL6II bacterial treatment. Therefore, these bacterial strains could be developed as potential PGP candidates for sustainable agriculture and might be utilized as bioinoculant for organic farming after further evaluation.
