Cysteine appeared to have two classes of growth inhibitory effect on Escherichia coli:
(1)Above 0·2 mm it inhibited growth on minimal medium by a mechanism which may involve interference with leucine, isoleucine, threonine and valine biosynthesis;
(2)above 2 mm, in media with these amino acids, it had an effect which may involve interaction with membrane bound respiratory enzymes.
Cysteamine showed only effect (2).
