"Sapromyces" Sabin 1941 non Fritsch 1893 Acholeplasma are wall-less bacteria in the Mollicutes class.

The genomes of Acholeplasma species range in size from 1.5 to 1.65 Mbp.

The species are found on animals, and some plants and insects.

[3] Acholeplasma laidlawii is a common contaminant of cell culture media products, and has also been used in extensive studies of lipid polymorphism because this organism alters its ratio of MGlcDG (monoglucosyl diacylglycerol) to DGlcDG (diglucosyl diacylglycerol) in response to growth conditions.
