[Effect of the antiseptic merthiolate and its derivatives on fungi causing deterioration].

The fungistatic activity of merthiolate and its two polymerous derivatives have been investigated using as test cultures fungi producing deterioration. The fungicides sorbtion dynamics by the fungus micelium have been studied, toxicity and inhibition rate of the catalase from different sources have been evaluated. The polymerous derivatives have been found to maintain high fungistatic activity of merthiolate, but possess less toxicity. The sorbtion of the polymerous derivative by the fungal mycelium takes place more effectively than the merthiolate sorbtion. The probable reasons of the high activity of the merthiolate polymerous derivatives are under discussion.
