Surfactants play an important role in enhanced oil recovery by creating an oil-water emulsion that will be easier to recover from the reservoir. It is known that sulfatereducing bacteria (SRB) can use surfactants as a carbon source, which can increase the biological accumulation of sulfides and, accordingly, the corrosion of oil production equipment. Thus, all new surfactants used in oil production need to be pre-tested for SRB. The aim of this study was to evaluate the effect of four new groups of synthesized surfactants on the growth of SRB. The well-known commercial preparation Atren SA (sample No 3) became the control sample. The results show that in the initial growth inhibition test, samples Nos. 2, 3, 5 do not allow SRB microorganisms to grow when plating. In samples No. 1 and 4, minimal growth of microorganisms was noted. In experiments on survival in samples Nos. 2, 3, 5 with a pre-extended culture, the death of SRB cells was noted within 10 days. In sample No. 1, the preservation of viable cells at the level of control values was noted, in sample No. 4, a slight growth of the culture was noted compared to the control. Thus, it can be noted that three new synthesized samples cannot consume these surfactants, and can be effectively used in the future.
