a microbial tapestry of very showy white filaments – bacterial trichomes or hair of Venus – that covered almost 2,000 square meters near the top of the Tagoro volcano, at a depth of between 129 and 132 meters, according to the images of an underwater vehicle revealed remotely controlled unmanned (ROV). The experts Galderic Lastras, David Amblàs, Anna Sánchez Vidal, Jaime Frigola, Antoni M. Calafat, Rut Pedrosa and Xavier Rayo, all from the GRC in Marine Geosciences, also participated in the research.from the UB, and Jesús Rivera, from the Spanish Institute of Oceanography ( IEO ), among others. Living in extreme environments at the bottom of the sea The underwater eruption in El Hierro substantially modified the underwater relief

. Initiated at a depth of 363 meters, the eruption originated a UAE WhatsApp Number List new volcanic cone and a cone of deposits that reached more than 1,000 meters deep. This geological episode, which lasted for 138 days, also radically altered the conditions of the ecosystem on a local scale (temperature, oxygen, acidity, turbidity, nutrients, etc.). According to Miquel Canals, head of the GRC in Marine Geosciences and director of the Department of Earth and Ocean Dynamics at the UB, “most of the volcanic activity on our planet takes place at the bottom of the sea.” “Until now,” Canals points out, “most of the bacterial communities related to underwater volcanic activity had been studied in the hydrothermal vents of the mid-ocean ridges. We are talking about

Extremophilic organisms, metabolically adapted to survive in highly limiting conditions for other living beings ». What is the origin of the bacteria discovered in the Tagoro volcano? The bacterium T. venerisIt represents not only a new species, but also a new genus of Extremophilic bacteria that was unknown to the scientific community. Without photosynthetic capacity, the new species shows a remarkable metabolic plasticity to obtain nutrients and energy even though it grows in relatively shallow volcanic beds, at least in the Tagoro. The new bacterium is phylogenetically close to other marine bacteria – specifically, to the genus Thioploca, within the class of gammaproteobacteria – endowed with great metabolic plasticity to adapt to the extreme
