Hans Buchner was a pioneer in the field of immunology. He was the first to discover a substance in blood serum that was capable of destroying bacteria. He called the substance "alexin", which was later named "complement" by Paul Ehrlich (1854–1915).[1]
In 1888 he introduced the pyrogallic method for cultivation of anaerobic bacteria.[2][3] Along with Martin Hahn, he assisted his brother, Eduard Buchner, with the isolation of zymase. Their findings were published in a 1903 treatise titled『Die Zymasegärung』(Zymase fermentation).[4]
