Isolation from Acid-Fast Bacteria of a Growth-Factor for Mycobacterium johnei and of a Precursor of Phthiocol

Nature volume 163, pages 365–366 (1949)Cite this article

Mycobacterium johnei will not grow on plain egg medium ; but Twort and Ingraham1 demonstrated that good growth could be ensured by the addition of acid-fast bacteria or products extracted from them with organic solvents.
