Microbiology (in Greek micron = small and biologia = studying life) is the study of microorganisms, including unicellular (single-celled) eukaryotes and prokaryotes, fungi, and viruses. ... Nitrification is the biological oxidation of ammonia with oxygen into nitrite followed by the oxidation of these nitrites into nitrates. ...
Winogradsky graduated from the University of Saint Petersburg. He discovered chemoautrophy, the process by which organisms derive energy from inorganic compounds and obtain carbon in the form of carbon dioxide.

Previously, the only known autotrophic organisms obtained energy from light, and not from chemical compounds. Winogradsky was one of the first researchers to attempt to understand microorganisms outside of the medical context, making him among the first students of microbial ecology and environmental microbiology.

Sergei Nikolaievich Winogradsky (or Vinogradskii; Russian: Сергей Николаевич Виноградский) (September 1, 1856- February 25, 1953) was a Russian microbiologist, ecologist and soil scientist who pioneered the cycle of life concept and discovered the biological process of nitrification, the first known form of chemoautotrophy.
Winogradsky was born in Kiev, in what was then the Russian Empire, and attended the University of Saint Petersburg in 1881, studying natural sciences and receiving a degree of master of science in botany in 1884.
Winogradsky is best known for discovering chemoautotrophy, the process by which organisms derive energy from a number of different inorganic compounds and obtain carbon in the form of carbon dioxide.
