Study on Growth Influencing Factors and Desulfurization Performance of <i>Sulfate Reducing Bacteria</i> Based on the Response Surface Methodology.

It can be seen from Figure 3 e that, with the extension of culture time, when the initial concentration of S 2– in the culture medium is 20, 40, and 60 mg/L, respectively, the SO 4 2– removal in the culture medium shows a decreasing trend, and the SO 4 2– removal rate is higher at 1∼5 days, while significantly reduced at 5∼8 days.

The results of RSM showed that the effects of culture temperature, environmental pH, and COD/SO 4 2– on the desulfurization performance of SRB were extremely significant.
