“…The generation of sulfide by SRB has both positive and negative economic implications. On the positive side, it contributes to the bioremediation of acid mine drainage sites by removing heavy metals as precipitated sulfides (Luptakova and Maria 2005). SRB activity also immobilizes toxic heavy metals such as chromium and uranium by reducing these to less mobile forms (Wall and Krumholz 2006).…”

Hydrogen sulfide, the metabolic end product of sulfate-reducing bacteria (SRB), is toxic to most life forms. This includes the SRB themselves. Although many of these are probably among the most sulfide resistant life forms, the presence of sulfide nevertheless presents a stress, which SRB must overcome. Although the response of SRB, especially the genus Desulfovibrio, to numerous stressors has been studied, their response to sulfide stress is unknown. We determined the effect of sulfide stress by comparing cells of Desulfovibrio vulgaris Hildenborough grown under conditions in which sulfide accumulated (high sulfide, 10 mM) with cells grown under conditions in which sulfide was removed by continuous gassing (low sulfide, 1 mM). High sulfide decreased the instantaneous growth rate constant and the final cell density of the culture by 52 and 33%, respectively, indicating a decreased bioenergetic fitness. Changes in gene expression caused by exposure to high sulfide were determined using full-genome D. vulgaris microarrays. The transcription of ribosomal protein-encoding genes was decreased, in agreement with the lower growth rate of D. vulgaris under high sulfide conditions. Interestingly, expression of the gene for DsrD, located downstream of the genes for dissimilatory sulfite reductase was also strongly down-regulated. In contrast, the expression of many genes involved in iron accumulation, stress response and proteolysis were increased. This indicates that high sulfide represents a significant stress condition, in which the bioavailability of metals like iron may be lowered. Overall this leads to a reduced growth rate and less efficient biomass production.

“…Hydrogen sulfide can also be produced by the biological sulfate reduction, using lactate, acetate or hydrogen as electron donor (Foucher et al, 2001;Gilbert et al, 2002;Herrera et al, 1997;Jong and Parry, 2003;Luptakova and Kusnierova, 2005). Elemental sulfur reduction by bacteria (X) is advantageous, since the H 2 S production by this method (Eq.…”

Feasibility of elemental sulfur reduction by Desulfovibrio desulfuricans in anaerobic conditions in a stirred reactor was studied. Hydrogen was used as energy source, whereas the carbonated species were bicarbonate and yeast extract. Attention was paid to reactor engineering aspects, biofilm formation on the sulfur surface, hydrogen sulfide formation rate and kinetics limitations of the sulfur reduction. D. desulfuricans formed stable biofilms on the sulfur surface. It was found that active sulfur surface availability limits the reaction rate. The reaction rate was first order with respect to sulfur and hydrogen velocity had no effect in the reaction rate for the range 8.2 x 10(-2) to 4.1 x 10(-1) Nm(3) m(-2) min(-1). At a superficial gas velocity (u(G)) = 3.1 x 10(-2) Nm(3) m(-2) min(-1), H(2)S(g) production rate decreased due to a deficient H(2)S stripping. A maximum H(2)S(g) production rate of 2.1 g H(2)S L(-1) d(-1) was achieved during 5 days with an initial sulfur density of 4.7% (w/v).

“…Mackinawite (FeS), which is inorganically prepared and is used to remove arsenic in groundwater, reduces As(III) into zero-valent arsenic As(0), surface clusters and a realgar (AsS)-like precipitate ). FeS has also been synthesized by reacting Fe(II) with sulfate produced during biotic sulfate reduction, and this has been shown to be a feasible scheme for the remediation of AMD Zagury et al, 2006;Luptakova and Kusnierova, 2005). In addition, FeS-based systems may have better hydraulic conductivity than systems using zero valent iron (Henderson and Demond, 2013).…”

Enhancing As(V) adsorption and passivation using biologically formed nano-sized FeS coatings on limestone: Implications for acid mine drainage treatment and neutralization

The iron-reducing bacterium Acidiphilium cryputum JF-5 and a sulfate reducing bacterium (SRB) collected and purified from the mine drainage of a copper mine in the northwest of Sichuan Province, China, were used to biologically synthesize nano-sized FeS-coated limestone to remove As(V) from solution. The adsorption efficiency of As(V) is improved from 6.64 μg/g with limestone alone to 187 μg/g with the FeS coated limestone in both batch and column experiments. The hydraulic conductivity of the columns are also improved by the presence of the nano-sized FeS coatings, but the solution neutralization performance of the limestone can be reduced by passivation by gypsum and Fe(III) precipitates. Calculations for FeScoated limestone dissolution experiments show that the process can be described as n Ca.sol =At 1/2 -n Ca,gyp .The results suggest that FeS-coated limestone may be an effective medium for remediating As(V)-bearing solutions such as acid mine drainage in systems such as Permeable Reactive Barriers 3
