Abstract

The escalating demand for chemical-free fertilizers in agriculture stems from the adverse impacts associated with chemical fertilizers on both human and animal health, as well as environmental pollution. To address this concern, plant-based microorganisms emerge as a promising solution for the development of environmentally sustainable biofertilizers. Among these microorganisms, endophytic bacteria, residing within plant tissues without causing harm to the host plant, exhibit exceptional attributes conducive to plant growth promotion. Notably, these bacteria demonstrate the production of phytohormones, ammonia, phosphate solubilization, and nitrogen fixation capabilities. Additionally, endophytic bacteria showcase the synthesis of hydrolytic enzymes, the production of siderophores, and antimicrobial activity against pathogens. Such characteristics contribute significantly to the robust growth and development of host plants, fostering tolerance to environmental stresses. This manuscript aims to comprehensively review the plant growth promotion activities of endophytic bacteria, elucidating their diversity and isolation from various plants. Furthermore, it explores the potential future directions in this burgeoning field of research, envisioning the development of endophytic bacterial strains capable of replacing traditional chemical fertilizers. Future research endeavors hold the promise of uncovering novel and effective endophytic bacterial strains, heralding a sustainable paradigm shift in the realm of agricultural fertilization.
