Thilo Böhm,Claus-Peter Klas,Matthias Hemmje assayed by the acetylene reduction method. Here, we describe the patterns of nitrogen fixation on two tufa forms before, during and after the bloom, as well as those from the planktonic cyanobacteria. We also analyzed the effect of ultraviolet radiation (under 390 nm) on the nitrogen fixation rates
