It was found that tannin and allied substances inhibited the decarboxylation of lysine and arginine by acetone-dried cells of Escherichia coli. The inhibition by gallotannin is far more marked in acetone-dried than intact cells and this seems to confirm the fact that the apparent weak inhibition is due to the difficulty of penetrating the cell membrane. Other substances had the same tendency to inhibit with acetonedried as with intact cells. This inhibition was not recovered by pyridoxal.
