Marine Pseudomonas: diving into the waves of blue biotechnology

From marine to terrestrial environments, Pseudomonas spp. exhibit a remarkable ability not only to adapt but also thrive even amidst adverse conditions. This fact turns Pseudomonas spp. into one of the most prominent candidates for novel biotechnological solutions. Even though terrestrial isolates have been extensively studied, there is still an almost untapped source to be explored in marine Pseudomonas. Harnessing such strains offers an opportunity to discover novel bioactive compounds that could address current global challenges in healthcare and sustainable development. Therefore, this minireview aimed to provide an overview of the main recent discoveries regarding antimicrobials, antifouling, enzymes, pigments, and bioremediation strategies derived from marine isolates of Pseudomonas spp. Future research perspectives will also be discussed to foster forthcoming endeavors to explore the marine counterparts of such a prolific bacterial genus.
