Earth's hidden carbon recyclers: Sulfur bacteria team up to break down organic substances in the seabed

Sulfate-reducing bacteria break down a large proportion of the organic carbon in the oxygen-free zones of Earth, and in the seabed in particular. Among these important microbes, the Desulfobacteraceae family of bacteria stands out because its members are able to break down a wide variety of compounds—including some that are poorly degradable—to their end product, carbon dioxide (CO2).

Water salinity affects diatom structure and metabolism, study shows

Scientists have found that an increase in water salinity in the cells of the marine diatom Nitzschia weakens the connections between the components of the photosynthetic apparatus and disrupts the formation of the cell shell.
