Abstract
A variety of bacterial genera coexists in natural environments and engages in mutualistic relationships that aid in their development and survival. The objective of this study was to prepare effective microbial consortia comprising potential endophytic bacteria that promote the growth of multiple plant species. These bacteria were isolated from the nodules and roots of Cicer arietinum. Five isolates, namely, CPJN13, CPSN8, CPHN4, CPHN2, and CPReR11, were selected to form the consortia. Compatibility tests were conducted to ensure the suitability of all isolates for consortia formation. Growth profile analyses indicated that the isolates exhibited rapid growth and were compatible. The consortia produced substantial amounts of indole-3-acetic acid, siderophores, and solubilized inorganic phosphate. In the pot experiment, there was significant enhancement in various plant growth parameters, including shoot and root length, as well as fresh and dry weight upon coinoculation of these cultures.
