Molecular advances are revolutionizing biogeochemistry by enabling the discovery of new microbes and metabolic pathways. This shift allows scientists to explore microbial roles in elemental cycles, transforming our understanding of global processes.

Area of Science:

  • Environmental Science
  • Microbiology
  • Geochemistry

Background:

  • Biogeochemistry traditionally studied processes first, then identified mediating microorganisms.
  • Molecular advances allow for a reverse approach, starting with genes and microbes.

Purpose of the Study:

  • To highlight the transformative potential of molecular approaches in biogeochemistry.
  • To advocate for a research focus on functional genes, microorganisms, and their community interactions.

Main Methods:

  • Sequencing functional genes directly from environmental samples.
  • Investigating microorganisms and their metabolic capabilities.

Main Results:

  • Discovery of novel microorganisms with unique metabolic functions.
