Use of plant growth promoting rhizobacteria (PGPR) is recently being studied for their ability to enhance growth of various plant species. Native bacteria with multiple PGPR attributes and ACC deaminase activity could be added advantage for making an isolate more potential PGPR. Five isolates with multiple PGPR traits and ACC deaminase activity were evaluated for their ability to show increase in plant growth. Results indicate that isolates IS-7 and IS-74 identified as Bacillus halotolerans (Accession No. OR593309) and Enterobacter hormaechei respectively were efficient compared to control plants and other isolates. Also, ability of these isolates in accumulation of total soluble sugars, proline and increased relative water content (RWC) of chilli indicate that they could be potential agents for alleviation of stress conditions
