Methane oxidation coupled to oxygenic photosynthesis in anoxic waters
Jana Milucka,Mathias K. Kirf,Lu Lu,Andreas Krupke,Phyllis Lam,Phyllis Lam,Sten Littmann,Marcel M. M. Kuypers,Carsten J. Schubert +8 more
TL;DR: The combined results from molecular, biogeochemical and single-cell analyses indicate that methane removal at the anoxic chemocline of Lago di Cadagno is due to true aerobic oxidation of methane fuelled by in situ oxygen production by photosynthetic algae.
Major role of planktonic phosphate reduction in the marine phosphorus redox cycle
B. A. S. Van Mooy,Andreas Krupke,Sonya T. Dyhrman,Helen F. Fredricks,Kyle R. Frischkorn,Justin E. Ossolinski,Daniel J. Repeta,Mónica Rouco,J. D. Seewald,Sean P. Sylva +9 more
TL;DR: Using simple incubation and chromatography approaches, the rate of the chemical reduction of phosphate to P(III) compounds in the western tropical North Atlantic Ocean is measured, suggesting the existence of a vast oceanic phosphorus redox cycle.

The effect of nutrients on carbon and nitrogen fixation by the UCYN-A–haptophyte symbiosis
Andreas Krupke,Wiebke Mohr,Julie LaRoche,Bernhard M. Fuchs,Rudolf Amann,Marcel M. M. Kuypers +5 more
TL;DR: The results reveal a direct linkage between the marine carbon and nitrogen cycles that is fuelled by the atmospheric deposition of dust and indicates an obligate symbiosis of this globally important diazotrophic association.
In situ identification and N2 and C fixation rates of uncultivated cyanobacteria populations
Andreas Krupke,Niculina Musat,Julie LaRoche,Wiebke Mohr,Bernhard M. Fuchs,Rudolf Amann,Marcel M. M. Kuypers,Rachel A. Foster +7 more
TL;DR: Two common co-occurring unicellular groups are identified and quantified and their cellular activities are measured by nanoSIMS, a globally important process often mediated by diazotrophic cyanobacteria in the open ocean.

Responses of the coastal bacterial community to viral infection of the algae Phaeocystis globosa.
Abdul Sheik,Corina P. D. Brussaard,Gaute Lavik,Phyllis Lam,Niculina Musat,Andreas Krupke,Sten Littmann,Marc Strous,Marcel M. M. Kuypers +8 more
TL;DR: Findings reveal a novel role of viruses in the leakage or excretion of algal biomass upon infection, which provides an additional ecological niche for specific bacterial populations and potentially redirects carbon availability.
