For decades, microbiologists have been studying Crocosphaera watsonii, a type of algae abundant in tropical and subtropical ocean waters. During the day, they convert carbon dioxide into sugar, and at night convert nitrogen into protein. Using these abundant gases allows them to fertilize the ocean, contributing to its carbon and nitrogen budgets. In a new paper, Takako Masuda, Jan Mares and Ondrej Prasil from Centre Algatech of the Institute of Microbiology CAS with colleague from University of Rhode island provide a long-awaited review and appreciation of this important single-cell organism. Reed more►
