About Sergei Winogradsky

  • Sergei Nikolaievich Winogradsky (or Vinogradskiy; Ukrainian: ?????? ??????????? ?????????????; 1 September 1856 – 25 February 1953) was a Russian microbiologist, ecologist and soil scientist who pioneered the cycle-of-life concept.Winogradsky discovered the first known form of lithotrophy during his research with Beggiatoa in 1887.
  • He reported that Beggiatoa oxidized hydrogen sulfide (H2S) as an energy source and formed intracellular sulfur droplets.
  • This research provided the first example of lithotrophy, but not autotrophy. His research on nitrifying bacteria would report the first known form of chemoautotrophy, showing how a lithotroph fixes carbon dioxide (CO2) to make organic compounds.
