Seeks Wenzel

Professor Wenzel Seifert (1862-1942) studied pharmacy and chemistry in Wien and devoted himself to chemistry, bacteriology and microscopy at the University of Wien . In 1890 he became assistant to Professor Leonhard Roesler (1839-1910) - his later father-in-law - at the Oenochemical Institute in the Department of Wine Chemistry at the Klosterneuburger Weinbauinstitut (Lower Austria). In 1893 he made his first experiments with purebred yeasts what became his specialty. In 1895, he set up a state-of-the-art laboratory and applied knowledge gained from brewing yeast to viticulture. Increasingly, he also dealt with chemical and microbiological tasks and published in 1901, a study on acidity in wine and thus refuted the hitherto prevailing opinion on the so-called second fermentation, He identified an acid-degrading bacterium and referred to it as "Micrococcus malolacticus" (see also malolactic fermentation ). In the following years he published on many topics such as the formation of glycerol during fermentation, the formation of acetic acid and about the sulphurous acid, In 1910 he became successor to Dr. Leopold Weigert Director of the Institute, which he headed until 1922. In his honor was created in 1970 in Klosterneuburg red grape variety as Seifert named.
