Nitrogen fixation in a nonheterocystous cyanobacterial mat from a mountain river [PDF]

open access: yes, 2016
In situ nitrogen fixation was investigated in a cyanobacterial mat growing on the bed of rocks of the Muga River, Spain. The filamentous non-heterocystous cyanobacterium Schizothrix dominated the mat, showing nitrogenase activity in the light at similar ...
