The fission yeast ''S. pombe'' is a unicellular eukaryote <ref>[https://en.wikipedia.org/wiki/Eukaryote Eukaryote Wiki. Retrieved 10/12/2017.]</ref> that is rod shaped. They measure approximately 2 to 3 microns in diameter and 7 to 14 microns in length. ''S. pombe'' is usually found in sugar-containing fermentations of alcohol from subtropical regions. Even though its origin dates back to quite a long time ago, it was not widely known before the 1890’s. It was discovered in 1893 when a group working in a Brewery Association Laboratory in Germany was looking at sediment found in millet beer imported from East Africa that gave it an unsavory acidic taste. P. Lindner was the first to describe ''Schizosaccharomyces pombe''. He chose as its epithet the Swahili word for beer, pombe. It was identified as yeast, and it became known as the fission yeast because it reproduces by means of fission unlike its relative ''Saccharomyces cerevisiae''. The name ''Schizosaccharomyces'' was assigned to it because "Schizo- " means different"split" <ref>[https://www.merriam-webster.com/dictionary/schizo- "SChizo-" Merriam-Webster.com. Retrieved 04/21/2021.]</ref>, which had been previously used to describe other fission species. <ref>[https://microbewiki.kenyon.edu/index.php/Schizosaccharomyces_pombe#Classification S. pombe Micro Wiki.

Dr. Matt Bochman has experimented fermenting beer with some strains of ''S pombe''. He reported that a lot of sulfurous compounds were produced, but this could have been just his strains or his fermentation conditions <ref>[https://www.facebook.com/groups/MilkTheFunk/permalink/1894065993954939/?comment_id=1897694636925408&comment_tracking=%7B%22tn%22%3A%22R%22%7D Matt Bochman.
