Virtanen, Artturi Ilmari (b. Jan. 15, 1895, Helsinki, Russian Finlandd. Nov. 11, 1973, Helsinki, Fin.), 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.

Virtanen, Artturi Ilmari Virtanen was educated at the university in his native city of Helsinki, where he obtained his PhD in 1919, and at the universities of Zurich and Stockholm. He worked from 1921 to 1931 as director of the Finnish Cooperative Dairies Association Laboratory and from 1924 at the University of Helsinki where, in 1931, he became director of the Biochemical Institute. In 1945 Virtanen was awarded the Nobel Prize for chemistry for his method of fodder preservation. This AIV method, as it became known, named for his initials, was designed to stop the loss of nitrogenous material in storage. By storing green fodder in an acid medium he hoped to prevent spoilage and still retain nutritious fodder. After much experimentation he finally found that a mixture of hydrochloric and sulfuric acid was adequate as long as its strength was kept within certain precise limits. Specifically, this demanded a pH of about four. In 1929 Virtanen found that cows fed on silage produced by his method gave milk indistinguishable in taste from that of cows fed on normal fodder. Further, it was just as rich in both vitamin A and C.

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. Categories 1895 births 1973 deaths Finnish scientists ...
