  • 🧍 The type strain of the species Myxococcus stipitatus is not available from any established culture collection or any other source. in 2009, E. Lang and E. Stackebrandt request that strain Mx s8 DSM 14675 JCM 12634 be formally recognized as the neotype strain for the species Myxococcus stipitatus, replacing the designated type strain Windsor M78. Opinion 102 granted this request. Publication: Lang E, Stackebrandt E.
