Description
Saverio Rana and co-authors report a 2026 study of two marine cyanobacteria that can fix nitrogen from the air. Their question was how the supply of nitrogen changes the way these cells share light energy between photosystem II and photosystem I. They grew Crocosphaera watsonii and Crocosphaera subtropica with and without a nitrogen feed.
Growth checks were paired with whole-cell light readings and glow tests run in deep cold. Batches fixing their own nitrogen shifted energy between the photosystems far more strongly than fed batches. One species shifted only while fixing nitrogen. The other also shifted as light levels changed. The work shows how energy spillover and antenna release help these cells stay safe when light runs too strong.
