Serratia marcescens Kayla Buchholz Serratia marcescens is a Gram negative, bacillus shaped bacteria that belongs to the family Enterobacteriaceae. In 1819, Bartolomeo Bizio, an Italian pharmacist from Padua, discovered S. marcescens. Bizio identified the bacterium as the cause of the miraculous bloody discoloration of cornmeal mush, or polenta. He named Serratia in honor of the Italian physicist Serratia who invented the steamboat, and named marcescens from the Latin word for decaying because the bloody coloration quickly disappeared. Key characteristics of S. marcescens include the production of Dnase, lipase and gelatinase, and it is oxidase negative.
