In this work the action of the following compounds upon Ps. aeruginosa acid phosphatase has been studied: 1) alkylammonium compounds; 2) aminoalcohols and aminoacids with different substituents (-H, -CH3OH and -CH3) attached to the nitrogen atom; 3) alcohols analogous to some compounds of the above series, but without the amino group.
