Megasphaera
Template:Short description Script error: No such module "Distinguish". Script error: No such module "Automated taxobox".
Megasphaera is a genus of Bacillota bacteria classified within the class Negativicutes.[1][2] Several species in the genus, including M. elsdenii and M. hexanoica, are known to utilize lactate.[3]
This classification has been reexamined.[4] This genus appears to be a member of the Clostridia.
