[The action of detergents upon microbes (author's transl)]
Abstract:
The effect of sodium dodecyl benzene sulphonate in the concentration range of 0.125%-1.0% upon gas formation by Klebsiella and Escherichia was studied. The experiments were performed in Szántha's gas tubes on synthetic culture media containing glycerol; gas formation was measured volumetrically. Concentrations below 1.0% were found to promote gas formation when compared with the control tubes. In accordance with previous papers published, enteric and chromogenic bacteria also multiplied well in the presence of 1.0% DBS-Na. It is shown by the results at hand that additional studies of the influence of detergents upon processes of self-purification in surface waters should be performed.
