Sulfate reducing bacteria (SRB) can simultaneously and efficiently remove SO 4 2− and heavy metal ions from acid mine drainage (AMD). Environmental factors have a great influence on AMD treated by SRB metabolic reducing sulfate. Providing a suitable growth environment can improve the effect of SRB on AMD. In this paper, the wet soil around the tailings reservoir was used as seed mud to enrich SRB. Based on the single factor experiment method and the response surface methodology (RSM), the effects of temperature, environmental pH value, S 2− concentration, and COD/SO 4 2− on the growth of SRB were analyzed. The effects of environmental factors such as temperature and pH on the desulfurization performance of SRB were investigated. The results showed that the growth curve of SRB was "S" type. SRB was in the logarithmic phase when cultured for 14−86 h, with high activity and vigorous growth metabolism. When the temperature is 32∼35 °C, the activity of SRB is the highest. With the gradual increase of the S 2− concentration in the culture system, SRB activity will be inhibited and even lead to SRB cell death. The environmental pH value that SRB can tolerate is 5∼8, and when the environmental pH value is 7∼8, the SRB activity is the strongest. The chemical oxygen demand (COD)/SO 4 2− that is most suitable for SRB growth is 2. The optimal growth conditions of SRB obtained from RSM were as follows: culture temperature at 34.74 °C, initial pH being 8.00, and initial COD/ SO 4 2− being 1.98. Under these conditions, the OD 600 value was 1.45, the pH value was 9.37, the oxidation reduction potential (ORP) value was −399 mV, and the removal percentage of SO 4 2− was 88.74%. 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. The order of affecting the removal of SO 4 2− by SRB was environmental pH > temperature > COD/SO 4 2− .

“…In the microbial treatment of AMD, sulfate-reducing bacteria (SRB) as the representative organisms has caused extensive research and application 5 . Muhammad et al 6 showed that under suitable conditions, SRB could survive in the environment containing sulfate and various metal ions, and the reduction reaction could reduce 87–100% of iron, lead, copper, zinc and aluminum. Sahinkaya et al 7 found that the final sulfate reduction rate could reach 90% in a sulfate-reducing MBR reactor when SRB was inoculated into wastewater with a sulfate concentration of 2000 mg/L and a COD/sulfate of 0.75.…”

Aiming at the problem that the treatment of acid mine drainage (AMD) by sulfate-reducing bacteria (SRB) biological method is susceptible to pH, metal ions, sulfate and carbon source. Lignite immobilized SRB particles (SRB-LP) and Rhodopseudomonas spheroides (R. spheroides) activated lignite immobilized SRB particles (R-SRB-LP) were prepared using microbial immobilization technology with SRB, R. spheroides and lignite as the main substrates. The dynamic experimental columns 1# and 2# were constructed with SRB-LP and R-SRB-LP as fillers, respectively, to investigate the dynamic repair effect of SRB-LP and R-SRB-LP on AMD. The mechanism of AMD treated with R-L-SRB particles was analyzed by scanning electron microscopy (SEM), fourier transform infrared (FTIR) spectrometer and low-temperature nitrogen adsorption. The result showed that the combination of R. spheroides and lignite could continuously provide carbon source for SRB, so that the highest removal rates of SO42−, Cu2+ and Zn2+ in AMD by R-SRB-LP were 93.97%, 98.52% and 94.42%, respectively, and the highest pH value was 7.60. The dynamic repair effect of R-SRB-LP on AMD was significantly better than that of SRB-LP. The characterization results indicated that after R-SRB-LP reaction, the functional groups of −OH and large benzene ring structure in lignite were broken, the lignite structure was destroyed, and the specific surface area was 1.58 times larger than before reaction. It illustrated that R. spheroides provided carbon source for SRB by degrading lignite. The strong SRB activity in R-SRB-LP, SRB can co-treat AMD with lignite, so that the dynamic treatment effect of R-SRB-LP on AMD is significantly better than that of SRB-LP.

“…The resistance of SRB to extreme conditions and the fact that sulphide reacts with several metals forming precipitates have made these microorganisms known for their potential in bioprocesses to treat waters contaminated with metals and sulphate, such as acid mine drainage (AMD) (e.g. Costa et al 2017;Dev et al 2017;Miran et al 2017;Muhammad et al 2017). However, these waters are usually poor in compounds used by SRB as carbon sources and electron donors to obtain energy, thus their biological treatment requires addition of such products (e.g.…”

Industrial by-products and wastes from Portugal and Spain were tested for the first time as carbon sources/electron donors for sulphate reducing bacteria. Cultures in mineral medium supplemented with the tested substrates were monitored and sulphate reduction efficiency is discussed in light of substrates compositions, dosages and corresponding chemical oxygen demand/[SO4 2-] ratios. The use of doses targeting a ratio of 1.5 was a good strategy to optimize sulphate reduction activity. As expected, this activity was faster for substrates that have in their composition simple compounds such as low chain alcohols and organic acids and/or compounds that can be rapidly degraded such as sugars, though it also occurred in a longer-term perspective with substrates composed mainly of slowly degradable compounds such as cellulose and lignin. Among eighteen tested substrates, six supported high sulphate reduction efficiency during incubation periods varying between two and four weeks (sugared water from a factory of candies, beetroot molasses, olive mill wastewaters not decanted and decanted, orange molasses without conservative and municipal wastewater from Mina de São Domingos, Portugal), while eight substrates sustained moderate sulphate reduction efficiency during periods from three to seven weeks (water from washing beetroots, Carbocal®, orange molasses with conservative, liquor extracted from orange peels, orange peel fragments, water from washing industrial equipments used to produce orange juice, pine nut shells and pine cone fragments). Nevertheless, after four months of incubation, total sulphate removal was observed with three of the solid substrates tested (orange peels, pine nut shells and pine nut cones).
