Happy to see this out @NatComm We found that the unicellular coastal cyanobacterium Cyanothece sp uses sodium energetics rather than the typical proton energetics to fix N2. Sodium energetics likely is more widespread and affects the global nitrogen cycle. Congrats Si Tang #microsky t.co/A4lIVcK2V3
