Sarcina is a genus of gram-positive cocci bacteria in the family Clostridiaceae.

[2][3][4] A synthesizer of microbial cellulose,[5] various members of the genus are human flora and may be found in the skin [6] and large intestine.

[7] The genus takes its name from the Latin word "sarcina," meaning pack or bundle, after the cuboidal (2x2x2) cellular associations they form during division along three planes.

[8] The genus's type species is Sarcina ventriculi, a variety found on the surface of cereal seeds, in soil, mud, and in the stomachs of humans, rabbits, and guinea pigs.

[9] The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN)[1] and National Center for Biotechnology Information (NCBI)[10] Clostridium tarantellae Clostridium perfringens S. maxima Lindner 1888 S. ventriculi Clostridium tarantellae (Udey, Young & Sallman 1977) Lawson & Rainey 2016 S. ventriculi Goodsir 1842 Clostridium perfringens (Veillon & Zuber 1898) Holland 1920 ex Hauduroy et al. 1937 "Clostridium massiliamazoniense" Dione et al. 2020 "Clostridium mediterraneense" Ndongo et al. 2017 This Clostridiales-related article is a stub.
