Serpentinite is a metamorphic rock resulting in the formation of serpentine minerals [1]. These minerals contain high levels of heavy metals, which provides a distinctive ecological niche for endolithic microbial communities. The endolithic bacteria found in serpentinite demonstrate a high resistance to heavy metals, the capacity to produce siderophores, and represent a valuable resource for understanding extremophile biology and for developing innovative biotechnological applications.

Endolithic bacteria have evolved unique adaptations to survive under extreme conditions, such as desiccation and nutrient limitation. The utilization of these bacteria for the improvement of soil in arid regions represents a promising strategy for the improvement of soil fertility and crop productivity. Pseudomonas chlororaphis is well known for its potential application in bioremediation, agriculture, and industrial biotechnology [2]. This bacterium produces different secondary metabolites, including pigments, antibiotics, and siderophores.

Thus, this study outlines the isolation and comprehensive characterization of serpentinite-derived strain Pseudomonas chlororaphis S15.
