Abstract Klebsiella pneumoniae , a Gram-negative bacterium with a long history of research and diverse applications, has attracted increasing interest in the agricultural field in recent years. This review explores the ability of K. pneumoniae strains to degrade various pollutants, such as pesticides, veterinary drugs, biological toxins, exogenous contaminants, and agricultural wastes (e.g., herbicide, polycyclic aromatic hydrocarbons, dyes, cellulose, and lignin). In addition to its ability to promote plant growth via mineral solubilization, phytohormone production, and nitrogen fixation, K. pneumoniae helps plants mitigate biotic and abiotic stresses through the production of antagonistic substances and the induction of systemic resistance or tolerance. Given these multifunctional capabilities, its considerable promise for use in biofertilization, bioremediation, and biocontrol is increasingly recognized, and with further research, K . pneumoniae is expected to play a more prominent role in sustainable agricultural production.
