Abstract
The effect of nystatin on the fresh-water algaHydrodictyon reticulatum was studied by estimating the electrical resistance of both the membranes and the intracellular fluid. The outflow of potassium ions into the external medium, occurring after addition of nystatin, was determined by flame photometry.
Values of ohmic resistance of membranes treated with nystatin ranged from 0.33 to 1.51 kΩcm2, the control values being 8.03–16.73 kΩcm2. Values of the resistance of intracellular fluid in nystatin-treated cells lay in the range of 3.21–7.13 kΩcm, those of control cells being 1.10 to 1.91 kΩcm.
The concentration of potassium ions in the external medium increased from 1.35 mM to 4.3 mM after addition of nystatin.
