Response of Nodularia spumigena to pCO2 – Part 2: Exudation and extracellular enzyme activities

Autor: Endres, Sonja, Unger, J., Wannicke, N., Nausch, M., Voss, M., Engel, Anja

Publikováno v: Biogeosciences, Vol 10, Iss 1, Pp 567-582 (2013)
Biogeosciences (BG), 10 . pp. 567-582.

The filamentous and diazotrophic cyanobacterium Nodularia spumigena plays a major role in the productivity of the Baltic Sea as it forms extensive blooms regularly. Under phosphorus limiting conditions Nodularia spumigena have a high enzyme affinity

New perspectives on nitrogen fixation measurements using N-15(2) gas

Autor: Wannicke, N., Benavides, Mar, Dalsgaard, T., Dippner, J. W., Montoya, J. P., Voss, M.

Recently, the method widely used to determine N-15(2) fixation rates in marine and freshwater environments was found to underestimate rates because the dissolution of the added N-15(2) gas bubble in seawater takes longer than theoretically calculated

Atmospheric CO2 availability does not equate to increased nodularin production in diazotrophic cyanobacteria, but does induce varying responses in net photosynthesis and N2 fixation rates

Autor: Michelle M. Gehringer, Wannicke N

Increasing levels of CO2in the atmosphere are suggested to favour increased incidences of cyanobacterial blooms in water bodies, with a potential concomitant increase in toxin production. As nitrogen fixing cyanobacteria are independent of nitrate an

Response of Nodularia spumigena to pCO2 – Part 1: Growth, production and nitrogen cycling

Autor: Wannicke, N., Endres, S., Engel, A., Grossart, H.-P., Nausch, M., Unger, J., Voss, M.

Heterocystous cyanobacteria of the genus Nodularia form extensive blooms in the Baltic Sea and contribute substantially to the total annual primary production. Moreover, they dispense a large fraction of new nitrogen to the ecosystem when inorganic n

Response of Nodularia spumigena to pCO2 - Part 3: Turnover of phosphorus compounds

Autor: Unger, J., Endres, Sonja, Wannicke, N., Engel, Anja, Voss, M., Nausch, G., Nausch, M.

Publikováno v: Biogeosciences (BG), 10 . pp. 1483-1499.

Diazotrophic cyanobacteria often form extensive summer blooms in the Baltic Sea driving their environment into phosphate limitation. One of the main species is the heterocystous cyanobacterium Nodularia spumigena. N. spumigena exhibits accelerated up
