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 sur...

The use of microalgae as carbon sequestrators requires optimization of the cultivation process. Growth curves for three types of microalgae were plotted. The growth was carried out at different temperatures 30 and 35 ? and with initially different concentrations of inoculum 30 and 3% in order to assess the possibility of growing crops at the lowest cost and with a high yield of a useful product. We used 3 strains of microalgae - potential sequestrators. The introduction of the inoculum at a dose of 30% led to an a...
