New model reveals adaptations of world's most abundant ocean microbe

Researchers from David Karl's laboratory at the University of Hawai'i at Mānoa (UHM) and from Professor Jens Nielsen's laboratory at Chalmers University of Technology in Göteborg, Sweden, developed a computer model which takes into account hundreds of genes, chemical reactions, and compounds required for the survival of Prochlorococcus, the most abundant photosynthetic microbe on the planet. They found that Prochlorococcus has made extensive alterations to its metabolism as a way to reduce its dependence on phosphorus, an element that is essential and often growth-limiting in the ocean.
