Plant Growth Promoting Rhizobacteria (PGPR) are a group of rhizospheric bacteria, found in association with plant roots and enhance the growth of plant directly or indirectly. To isolate multi-trait PGPR, total 7 soil sample were collected from sugarcane rhizosphere with diverse previous cropping pattern. Total 38 distinct isolates were obtained in pure culture from above collected samples, were screened for their ability of plant growth promoting characters in in vitro conditions. Out of this, 100% showed antagonistic potential, 55.26%, 42.11% and 52.63% were positive for protease, amylase and lipase secretion respectively. In terms of increase in nutrient availability, 18.42%, 39.47%, 26.32% and 31.58% were showing positive phosphate solubilization, potash mobilization, zinc solubilization and nitrogen fixation respectively. Indole-3-acetic acid production was detected in 31.58% isolates. Least per cent of isolates i.e. 13.16% were found positive for ACC deaminase activity. Two multi-trait and most potent PGPR isolates were screened and identified as Myroids profundi and Proteus mirabilis on the basis of 16s r-RNA sequencing method.
