Sergey Nikolayevich Winogradsky

Died 25 Feb 1953 at age 96 (born 1 Sep 1856).Russian microbiologist who helped to establish bacteriology as a major biological science. He was first to isolate the bacteria responsible for nitrification and nitrogen fixation by soil bacteria (1890).Winogradsky also studied bacteria that recycle other vital elements for use by other organisms - including ‘iron bacteria', and those which metabolize sulfur (1887-9) - deriving metabolic energy from inorganic nutrients. Previously, only organic substrates were considered suitable for microbes. The "Winogradsky column" is still used as an enrichment culture that simulates the muddy habitat of anoxygenic photosynthetic bacteria.[Name also spelled Sergei or Sergius.]
