Endophytes play a pivotal role in sustainable agriculture due to their capacity to generate numerous agriculturally significant metabolites. This study focuses on isolating a salt-tolerant, fluorescent green pigment-producing endophytic bacterium from the leaf samples of Aronia prunifolia cultivated on 2.5% Sodium chloride (NaCl) supplemented nutrient agar. After thoroughly examining the roots' isolated strain, EB-3, it has been identified as Pseudomonas putida. This identification was based on a detailed analysis of its morphological and biochemical characteristics, coupled with the scrutiny of its 16S rDNA sequence. Extensive biochemical and functional studies have revealed the diverse capabilities of P. putida. This bacterium excels in producing hydrogen cyanide (HCN), siderophore, indole acetic acid (IAA), and demonstrates proficiency in phosphate solubilization. These findings emphasize the potential of P. putida as a valuable bacterial inoculant for sustainable agriculture, especially in challenging environments. The versatility of this strain in producing beneficial metabolites underscores its crucial role in promoting agricultural resilience and productivity. Consequently, P. putida emerges as a promising ally in advancing sustainable agricultural practices, particularly in stressful conditions.
