Overview

Rudolf Amann is affiliated with the Max Planck Institute for Marine Microbiology in Germany. Their research primarily focuses on environmental science, particularly within subfields such as ecology, molecular biology, environmental chemistry, oceanography, and global and planetary change. The work strongly emphasizes microbial community ecology and physiology as well as genomics and phylogenetic studies.

Their research outputs reflect consistent contributions across several themes including methane hydrates and related phenomena, marine and coastal ecosystems, protist diversity and phylogeny, marine biology and ecology research, and bacteriophages and microbial interactions.

Rudolf Amann has published extensively in prominent scientific venues. Frequent publication outlets include:

  • bioRxiv (Cold Spring Harbor Laboratory)
  • The ISME Journal
  • Systematic and Applied Microbiology
  • Environmental Microbiology
  • Nature Communications

The scientist has collaborated regularly with several co-authors, featuring repeated partnerships with Bernhard M. Fuchs (39 publications), Ramon Rosselló-Mora (21 publications), Carol Arnosti (18 publications), Tomeu Viver (18 publications), and Jan-Hendrik Hehemann (17 publications).

Some notable recent papers authored or co-authored by Rudolf Amann include:

  • The Biogeochemistry of Marine Polysaccharides: Sources, Inventories, and Bacterial Drivers of the Carbohydrate Cycle (2020) published in Annual Review of Marine Science
  • Verrucomicrobiota are specialist consumers of sulfated methyl pentoses during diatom blooms (2021) published in The ISME Journal
  • Roadmap for naming uncultivated Archaea and Bacteria (2020) published in Nature Microbiology
  • An ANI gap within bacterial species that advances the definitions of intra-species units (2023) published in mBio
  • Diatom fucan polysaccharide precipitates carbon during algal blooms (2021) published in Nature Communications

The research fields covered by Rudolf Amann broadly intersect with both environmental science and biochemistry, genetics, and molecular biology. The sub-disciplines and research topics reflect a strong interdisciplinary approach blending ecological, molecular, and chemical perspectives relevant to marine microbiology and microbial ecology.

In 1979, Rudolf Amann was recognized with the Animal Physiology and Endocrinology Award from the American Society of Animal Science.
