Investigations of the effect of low concentrations of Fentichlor on the metabolic activities of Staphylococcus aurew and Escherkhk coli indicate that the bacteriostatic action of the drug results from a specific inhibition of metabolic reactions within the cell which are energy‐requiring. Bacteriostatic concentrations of Fentichlor inhibit energy dependent uptake of amino acids, assimilation of amino acids and glucose into cellular material and total protein synthesis. In contrast, energy‐independent uptake of amino acids and the uptake of glucose is little affected. These concentrations do not inhibit respiratory enzymes and selective inhibition of energy metabolism by Fentiohlor probably results from a disruption of the mechanism of energy coupling within the cell.
