In 1945 Virtanen became Nobel Prize Laureate in Chemistry, for his research in agricultural and nutrition chemistry, especially for his fodder preservation method (AIV Fodder). The method – which he had published 1943 - improved the storage of green fodder that is important during long winters. Process includes adding dilute hydrochloric or sulfuric acid to newly stored grain. Increased acidity stops harmful fermentation and has no adverse effect on the nutritive value of the fodder or animals that eat it. This article is from Wikipedia .

Artturi Ilmari Virtanen Artturi Ilmari Virtanen Finnish biochemist whose investigations directed toward improving the production and storage of protein-rich green fodder, vitally important to regions characterized by long, severe winters, brought him the Nobel Prize for Chemistry in 1945. As a chemistry instructor at the University of Helsinki (1924-39), where he became professor of biochemistry (1939-48), Virtanen studied the fermentation processes that spoil stores of silage. Knowing that the fermentation product, lactic acid, increases the acidity of the silage to a point at which destructive fermentation ceases, he developed a procedure (known by his initials, AIV) for adding dilute hydrochloric or sulfuric acid to newly stored silage, thereby increasing the acidity of the fodder beyond that point. In a series of experiments (1928-29), he showed that acid treatment has no adverse effect on the nutritive value and edibility of the fodder and of products derived from animals fed the fodder. Virtanen was also a professor of biochemistry at the Helsinki University of Technology (1931-39) and director of Finland's Biochemical Research Institute, Helsinki, from 1931. He did valuable research on the nitrogen-fixing bacteria in the root nodules of leguminous plants, on improved methods of butter preservation, and on economical, partially synthetic cattle feeds. His AIV System as the Basis of Cattle Feeding appeared in 1943.

Artturi Ilmari Virtanen 1. Johdanto Artturi Ilmari Virtanen on edelleen tunnetuin suomalainen kemisti niin kotimaassaan kuin ulkomaillakin. Häntä pidetään tieteellisen sekä opetustyönsä ansiosta Suomen biokemian isänä. Virtasen tutkimustoiminta oli harvinaisen laajaa: kuuluuhan hänen nimiinsä noin 1400 tieteellistä julkaisua, jotka koskevat orgaanista ja analyyttista kemiaa, biokemiaa, mikrobiologiaa, kasvifysiologiaa, meijerioppia, maataloutta sekä ravitsemus- ja lääketiedettä. Parhaiten hänet tunnetaan AIV-rehustaan, jonka johdosta hän vuonna 1945 sai kemian Nobel-palkinnon. 2. Artturi Ilmari Virtasen henkilöhistoria Artturi Ilmari Virtanen syntyi 15.1.1895 Helsingissä, joskin hän muutti jo pienenä Viipuriin. Hän kävi Viipurin lyseon, jonka suoritti erinomaisin arvosanoin. Lyseon jälkeen hän aloitti opinnot keisarillisessa Aleksanterin yliopistossa Helsingissä, missä opiskeli kemiaa, biologiaa ja fysiikkaa. Hän suoritti kandidaatintutkinnon vuonna 1916 pääaineenaan kemia, ja tohtoriksi hän valmistui vuonna 1919 jo 24-vuotiaana väitellen pinabietiinihapon rakenteesta (ks. myös Liite 1 Virtanen työskenteli Ossian Aschanin alaisuudessa. Hän toimi Valion kemistinä pari vuotta ja opiskeli sinä aikana muun muassa fysikaalista kemiaa Zürichissä, rasvakemiaa Münsterissä ja bakteriologiaa Tukholmassa. Laboratorion johtajaksi hän ryhtyi vuonna 1921. Virtanen pysyi koko tutkijanuransa aikana valiolaisena. Hänet nimitettiin 1931 teknillisen korkeakoulun biokemian professoriksi, ja 1939 Helsingin yliopiston biokemian professoriksi. Virtanen siirtyi Suomen Akatemian esimieheksi 1948 ja koko ajan hän johti Valion tutkimuksia. Hän loi laajat suhteet ulkomaisiin tiedeyhteisöihin jo nuorena tutkijana, mikä avasi ulkomaat myös muille suomalaisille opiskelijoille. Virtanen oli erittäin monipuolinen biokemisti.

Artturi Ilmari Virtanen was born in Helsinki on the 15th of January, 1895, as the son of Kaarlo Virtanen and Serafiina Isotalo. He was educated at the Classical Lyceum at Viipuri, Finland. After finishing school, he studied chemistry, biology, and physics at the University of Helsinki , where he took his M.Sc. in 1916 and obtained his D.Sc. in 1919. Subsequently he studied physical chemistry in Zurich in 1920 under G. Wiegner, bacteriology in Stockholm in 1921 under Chr. Barthel, and enzymology in Stockholm during 1923-1924 under H. von Euler . Since 1923, his interest turned to biochemistry. He was first-assistant of the Central Laboratory of Industries at Helsinki during 1916-1917, and chemist in the Laboratory of Valio, Finnish Cooperative Dairies' Association, during 1919-1920. In 1921 he became Director of this laboratory, and in 1931 of the Biochemical Research Institute at Helsinki. After having been docent in chemistry at the University of Helsinki since 1924, he was appointed Professor of Biochemistry at the Finland Institute of Technology at Helsinki in 1931, and at the University of Helsinki in 1939. Since 1948 he has been member and President of the State Academy of Science and Arts in Finland. Professor Virtanen is a member of the Finnish, Norwegian, Swedish, Flemish, Bavarian, and Pontifical Academies of Science, and of the Swedish and Danish Academies of Engineering Sciences. He is an honorary member of learned societies in Finland, Sweden, Austria, Edinburgh, and the U.S.A., and holds honorary degrees of the Universities of Lund, Paris
