Mining Microbial Niches: Sources of Bacteria for Enhancing Plant Growth and Resilience to pH, Salinity, Drought and Phytophthora infestans.

ABSTRACT: Enhancing plant resilience is crucial for sustainable agriculture and ecosystem health in an era of climate change and the global spread of plant pathogens. The strategic exploitation of diverse ecological niches to isolate microorganisms that promote plant growth, suppress pathogens and tolerate abiotic stress conditions is paramount. Here, 21 bacterial strains were isolated from three distinct sources: digestate produced from straw feedstock, Quercus ilex roots mycorrhised with Tuber aestivum, and a peperino stone fountain. These isolates were assigned to eight genera, Bacillus, Pseudomonas, Stenotrophomonas, Burkholderia, Acinetobacter, Aeromonas, Exiguobacterium and Sphingobacterium, all linked to plant growth promotion, stress mitigation and pathogen control.
