The deep, light-free zone of the ocean, located between 200 and 1,000 meters below the surface, is surprisingly poor in iron, to the point of limiting the growth of bacteria, which, however, they compensate by producing molecules that facilitate their absorption from the surrounding water:this is what emerges from new research led by scientists from the University of South Florida, subjected to peer review and published in the prestigious scientific journal Nature.The authors explained that the experiment could revolutionize our understanding of microbial processes in the deep oceans and, above all, provide new estimates and parameters regarding carbon uptake by the oceans, which strongly depends on bacterial activity and is essential for mitigating climate change. The analyzed region, called “twilight zone”, is characterized by the fact that sunlight cannot penetrate, thus creating a dark and cold environment.The lack of sunlight therefore limits photosynthesis and, conseq...
