The effect of certain anionic detergents on the process of desulfurication

The effect of sodium dodecylsulphate (SDS), sodium alkilbenzenesulphonate ( ABSNa) and sulphosuccinates IOP5 and N5, present in different concentration s, on the kinetics of desulfurication conducted with the use of Desulfotoma culum ruminis bacteria was analysed. As follows from the determined activit y of the microorganisms, the presence of SDS and ABSNa inhibits the process of desulfurication. The toxic concentrations of these compounds were estab lished as 60 mg/dm(3) for SDS and 450 mg/dm(3) for ABSNa. The presence of s ulphosuccinates IOP5 and N5, even at the concentration of 20g/dm(3), does n ot affect the activity of Desulfotomaculum ruminis bacteria but these compo unds cannot be used as a source of carbon by the microorganisms.
