Shimwellia
Scientific classification
Domain:	Bacteria
Phylum:	Pseudomonadota
Class:	Gammaproteobacteria
Order:	Enterobacterales
Family:	Enterobacteriaceae
Genus:	Shimwellia; Priest and Barker 2010
Species
	S. blattae; S. pseudoproteus

Shimwellia is a genus of Gram-negative bacteria of the family Enterobacteriaceae. The two species of Shimwellia are Shimwellia blattae (formerly Escherichia blattae) and Shimwellia pseudoproteus (formerly Obesumbacterium pseudoproteus).[1]

Species in Shimwellia are genetically similar to Escherichia but differ in notable ways. S. blattae can synthesize coenzyme B12[2] and S. pseudoproteus is associated with beer spoilage.[3][4]
