- 🧍 The strain NCIMB 8052 (= ATCC 51743 = IAM 19013), originally deposited and catalogued as the type strain of Clostridium acetobutylicum, is not equivalent to ATCC 824 or DSM 792. The strain NCIMB 8052 is in fact Clostridium beijerinckii. Publication: Wilkinson SR, Young M, Goodacre R, Morris JG, Farrow JAE, And Collins MD.
