Dinitrogen fixation in the unicellular diazotroph Crocosphaera watsonii

Crocosphaera watsonii is an abundant organism in the tropical and subtropical ocean and is considered to be an important contributor to the marine nitrogen cycle due to its ability to fix dinitrogen (N2). Light-dark cycles were used to determine the diel variation in N2 fixation and photosynthesis in...
