Summary

Two novel predatory bacteria, Vampirococcus and Daptobacter, were discovered in Spanish lakes. These findings reveal ancient microbial predation predating eukaryotes and offer insights into organelle origins.

Area of Science:

  • Microbiology
  • Evolutionary Biology
  • Ecology

Background:

  • Predatory prokaryotes play a crucial role in microbial ecosystems.
  • Understanding diverse predatory mechanisms is key to evolutionary studies.

Purpose of the Study:

  • To characterize newly discovered predatory bacteria from Spanish freshwater sulfurous lakes.
  • To investigate the evolutionary implications of prokaryotic predation.

Main Methods:

  • Light and electron microscopy for bacterial characterization.
  • Direct cell counts in natural samples to infer ecological roles.

Main Results:

  • Vampirococcus, an anaerobic epibiont, adheres to and destroys phototrophic bacteria.
  • Daptobacter, a facultative anaerobe, invades and grows within prey cytoplasm.

  • Three distinct predatory prokaryote types are now known: epibiotic, cytoplasmic, and periplasmic.

    • Conclusions:

    • Antagonistic microbial relationships evolved before eukaryotes.
    • Prokaryotic predation mechanisms represent preadaptations for the origin of intracellular organelles.
