1. MH was found to suppress the growth and respiration of E. coli as well as the IAA-induced growth of Avena coleoptile sections. 2. These suppressions could be reversed more or less strikingly by the addition of a trace of heavy metals such as Co, Mn, Ni. Zn, Cu, or Mo. 3. The reversal could also be achieved by cysteine. thioglycollate, or fumarate, the latter two substances being, however, less effective. 4. The inhibition of the growth of E. coli by MH was completely relieved by the addition of IAA. Conversely, the inhibition of the microbial growth by high concentrations of IAA could be relieved by the addition of MH. 5. It was inferred that MH may block certain heavy metal-catalyzed process, in which some thiol substance and IAA are participating, probably by combining with the heavy metal.
