The effects of cadmium and lead ions on bacterial ectoenzymatic activities and on the rates of organic substrates uptake were investigated in short-period experments.Both the acivitiees of ectoenzymes and rates of organic substrates uptake by bacteria were strongly inhibited by studied metal ions even in their low concentrations.Three types of inhibition: competitive (aminopeptidase) ,noncompetitive (lipase) and mixed (alkaline phosphatse) due to Pb and Cd ions were observed.The potential mechanisms of changes of the physical and chemical properties of studied enzymes by cadmium and lead were discussed.
