Study on removing selenate from groundwater by autohydrogenotrophic microorganisms

Siqing XIA, Shuang SHEN, Jun LIANG, Xiaoyin XU

Frontiers of Environmental Science & Engineering 2013, Volume 7, Issue 4,   Pages 552-558 doi: 10.1007/s11783-013-0531-2

Abstract: Performance of autohydrogenotrophic bacteria for bio-reduction of selenate (Se(VI)) under anaerobic conditions was investigated with batch experiments. Results showed Se(VI) was bio-reduced to selenite (Se(IV)) as an intermediate product, and then to elemental selenium (Se ). Reduction kinetics could be described by the pseudo-first-order model. In particular, the influences of pH value and temperature on Se(VI) reduction by autohydrogentrophic organisms were examined. The high degradation rate was achieved at pH 7.0 to 8.0; and the best reduction temperature was between 25°C and 35°C. This study is of help for treating groundwater with selenium contamination by autohydrogenotrophic bacteria as well as its reactor development.

PSS sorbents for removing trace hydrogen sulfide in methane

Limei ZHONG, Li ZHOU

Frontiers of Chemical Science and Engineering 2011, Volume 5, Issue 3,   Pages 339-342 doi: 10.1007/s11705-010-0569-7

Abstract: Sorbents of the pressure swing sorption process (PSS) to remove trace amount of H S (190 ppm) contained in methane were experimentally studied. The sorbents consist of adsorbent carrier (silica gel or activated carbon) and absorbent which spreads outside the carrier granules’ pores (triethanolamine, TEA or -methyl-2-pyrrolidone, NMP). The results of breakthrough and regeneration tests show that silica gel is more suitable to be the carrier than activated carbon and TEA is more suitable to be the absorbent than NMP. The loaded absorbent could enlarge the sorption capacity of H S considerably. And the BET tests indicate that the absorbent deposits on the surface of the carrier’s pores and can reduce the mesopores’ size and block the micropores.

Frontiers of Environmental Science & Engineering 2021, Volume 15, Issue 4, doi: 10.1007/s11783-020-1349-3

Abstract: Abstract • Pseudomonas mendocina was first reported for aerobic nitrate removal. • It removed 90% of NO3−-N in 24 h under aerobic conditions. • This strain converted NO3−-N to bio-nitrogen (37.9%) and gaseous nitrogen (49.7%). • Inoculation of this strain increased sludge denitrification rate by 4.3 times. The problem of nitrate accumulation in aerobic tank and total nitrogen excessive discharge in effluent was very common in traditional livestock and poultry farming wastewater treatment systems owing to the lengthy process flow and low process control level. A strain LYX of aerobic bacterium was isolated from the activated sludge of a wastewater treatment system in a pig farm, which could remove nitrate effectively in aerobic tank and was identified Pseudomonas mendocina by 16S rRNA sequencing. Under the condition of nitrate as the sole nitrogen source, this strain removed over 90% of NO3−-N with an initial concentration of 110 mg/L under aerobic conditions within 48 hours. Among them, 37.9% of NO3−-N was assimilated into Bio-N, about 51.9% was reduced to gaseous nitrogen and less than 0.5% of nitrogen was replaced by NO2−-N and NH4+-N, 9.7% NO3−-N remained in the effluent at the end. At the same time, four key genes (napA, nirK, norB and nosZ) related to nitrate nitrogen removal were expressed during the denitrification process of P. mendocina LYX, in which the transcription level of the indicator genes of this aerobic denitrifying bacterium (napA) was the highest. In addition, it was found with the 15N tracer technique that inoculation of this strain on sludge increased the amount of nitrogen loss from 9.26 nmol N/(g·h) to 23.835 nmol N/(g·h). Therefore, P. medocina LYX is a potential bioagent for advanced nitrogen removal by assimilating and reducing nitrate simultaneously in aerobic tanks.
