Sugar turns brown algae into good carbon stores: Only highly specialized bacteria can carry out the degradation of brown algae with the help of more than hundred enzymes

Brown algae are important players in the global carbon cycle by fixing large amounts of carbon dioxide and thus extracting this greenhouse gas from the atmosphere. Moreover, because microbial decomposition of dead brown algae is slower than that of other marine plants, carbon dioxide fixed by brown algae remains much longer in the sea.
