Emil Christian Hansen (May 8, 1842 – August 27, 1909) was a Danish mycologist and fermentation physiologist.
Ribe, he financed his education by writing novels. He was awarded a gold medal in 1876 for an essay on fungi, titled De danske Gjødningssvampe. During his days as a university student in [1 ] Copenhagen, he worked as an unpaid assistant to zoologist Japetus Steenstrup (1813–1897). In 1876, with Alfred Jørgensen (1848–1925), he published a Danish translation of Charles Darwin’s " The Voyage of the Beagle"; Rejse om Jorden. From 1879 to 1909, he was director of the physiological department at Carlsberg Laboratory. [2 ]
Employed by the
Carlsberg Laboratory in Copenhagen, he discovered that yeast was composed of different kinds of fungi and that the yeast culture could be cultivated. He isolated a pure cell of yeast, and after combining it with a sugary solution, produced more yeast than was in a yeast bank. It was known as , and is used in Saccharomyces carlsbergensis lager beers. See [3 ] Fermentation, Yeast.
Hansen is the
taxonomic authority of the fungal genus Anixiopsis (1897) from the family Onygenaceae. [4 ]
