The paper was aimed at studying the effects of different detergent (Meril, Merima - Krusevac (Serbia)) concentrations, introduced into the nutritive medium, on the total number of soil microorganisms, fungi and oligonitrophiles. The results obtained showed that the lowest possible toxic effect on the microorganism groups studied was produced by the lowest detergent concentration (0.001%), whereas the concentrations of 0.1%, and particularly of 1% solution, inhibited microorganism growth early utterly. In this sense, oligonitrophilous bacteria appeared to be the most sensitive and soil fungi the most resistant group of microorganisms.
