Soil contamination by heavy metals and polycyclic aromatic hydrocarbons (PAHs) poses a significant threat to food safety, soil fertility and sustainable agricultural productivity. Plant growth-promoting rhizobacteria (PGPR) provide eco-friendly strategies for enhancing crop growth while mitigating environmental pollutants. Legume associated rhizobacteria are particularly valued for their adaptive resilience under stress conditions. This study evaluated PGPR isolated from the rhizosphere of pea (Pisum sativum L.) for heavy metal tolerance and pyrene biodegradation under in-vitro conditions. A total of twenty bacterial isolates were obtained and screened for plant growth promoting traits including indole-3-acetic acid (IAA) production, phosphate solubilization, ammonia production, siderophore production, hydrogen cyanide production and nitrogen fixation potential. Among them, isolates P2B and P3A demonstrated superior multifunctional performance. Isolate P2B exhibited higher IAA production (59.25 µg mL⁻¹ at 144 h) and strong siderophore production (88.26% SU), whereas P3A showed enhanced ammonia production and broader metabolic versatility. Both isolates displayed substantial tolerance to Ni, Co, Cr and Cd, with P3A showing greater resistance to cobalt and cadmium. Growth in pyrene amended media revealed concentration dependent adaptation and efficient biodegradation, achieving 99% and 98% pyrene degradation after 21 days by P2B and P3A, respectively. Biochemical characterization and 16S rRNA gene sequencing identified the isolates as Pseudomonas glycinae (P2B) and Priestia aryabhattai (P3A). The combined expression of plant growth promoting traits, multi-metal tolerance and pyrene degradation capacity highlights these strains as promising multifunctional bioinoculants for sustainable bioremediation of contaminated agricultural soils.
