Sergei N. Winogradsky

Born in 1856. Educated in Kiev, St. Petersburg, Strasbourg and University of Zurich. As a Head of Department of General Bacteriology Petersburg. Bacterial Winogradsky work on sulfur and in particular over the nitrifying bacteria were the era of bacteriology. Before Vinogradova considered certain that the bacteria can eat only organic substances. Vinogradov proved that bacteria can eat well and such minerals, which, like the organic, contain a reserve of energy, meaning they can burn. He received nitrifying bacteria in pure culture, feeding them exclusive mineral compounds. Source is a well-burning ammonia. Glucose was for these bacteria poison. For this work, Kharkov University gave Vinohradskц? doctorate honoris causa Botany. Then Vinogradskiy found bacteria that feed on free atmospheric nitrogen. Thanks to his method of feeding minerals were discovered bacteria that feed on free hydrogen, a source of energy is good here burning hydrogen. Major works Winogradsky: "Ueber Schwefelbakterien" ( "Bot. Ztg. "1887, N 31 - 37);" Ueber Eisenbacterien "(" Bot. Ztg. ", 1888, N 17);" Zur Morphologie u. Physiologie der Schwefelbacterien "(Beitrage zur Morphologie und Physiologie der Bacterien", Leipzig, 1888); "Recherches sur les organismes de la nitrification" ( "Ann. de l'Inst. Pasteur ", N 4, 5, 12, 1890; t. 5, 1891).
