Abstract
Numerous microbes reside in the rhizosphere having plant growth promoting activity, and enhancing the property by increasing plant yield. Plant growth promoting rhizobacteria (PGPR) has gradually increased in agriculture and offers an attractive way to replace chemical fertilizers, pesticides and supplements. Soil was collected from the rhizosphere of an agricultural farm and the psychrotrophic bacterial strains STA3 (KY888133) and RM2 (KY888134) were successfully isolated, and screened on the basis of phosphate solubilization. Further characterization was carried out by morphological, biochemical, and 16S rDNA characterization methods. The unique nature of psychrotrophic Pentoea ananatis and a suitable combination with Pseudomonas fluorescens regarding plant growth promotion activity has not been studied before to our knowledge. An assessment of various parameters of plant growth promoting activity, such as IAA, phosphate solubilization, bio-control activity, HCN and siderophore production, has been carried out. Both strains were found to be positive in various parameters except HCN and Biocontrol activity, which were positive only for the strain RM2. Also, shelf life and efficacy was d...
