    Bioscorodite crystallization using Acidianus brierleyi: Effects caused by Cu(II) present in As(III)-bearing copper refinery wastewaters
    © 2016 Elsevier B.V. This study investigated the effect caused by Cu(II) in synthetic As(III)-bearing copper refinery wastewaters, on microbial scorodite (FeAsO4·2H2O) formation using the thermo-acidophilic Fe(II)- and As(III)-oxidizing archaeon, Acidianus brierleyi. Microbial Fe(II) oxidation and cell growth became only marginal in the presence of 8–16 mM Cu(II), with its As(III) oxidation ability being severely inhibited. Consequently, scorodite formation was disabled by Cu(II) addition. However, feeding scorodite seed crystals readily alleviated Fe(II)- and As(III)-oxidation ability of Ac. brierleyi at 8 mM Cu(II), forming crystalline scorodite within 24 days in shake flasks. Zeta potential analysis indicated cell attachment to the scorodite seed crystal surface, implying its role in providing the immediate support for microbial colonization and enabling more robust microbial reactions. Most of Cu(II) was neither adsorbed nor co-precipitated and remained in the solution phase during scorodite crystallization, with or without the presence of seed crystals. Addition of seed crystals at 0.015, 0.03, 0.075 and 0.15% resulted in As immobilization of 96, 97, 97 and 98%, respectively, by day 24. This study demonstrated that despite of its inhibitory effect on Ac. brierleyi cells, scorodite can still be crystallized in the presence of Cu(II) by feeding scorodite seeds from synthetic copper refinery As(III)-bearing wastewaters.

    Comparison of atmospheric citric acid leaching kinetics of nickel from different Indonesian saprolitic ores
    © 2016 Elsevier B.V. All rights reserved. Saprolitic ores from Sulawesi Island (SS ore) contain serpentine and goethite as major minerals, whereas the main minerals in saprolitic ore from Halmahera Island (SH ore) are talc and goethite. Most of the nickel was incorporated in a magnesium-silica-containing mineral. The effects on nickel extraction of leaching temperature, citric acid concentration, and ore particle size were determined to investigate the leaching performances and leaching kinetics of the two saprolitic ores. Nickel leaching efficiency from SS ore is always higher than that from SH ore under the same leaching conditions. The mineral contents of the ores significantly affected the leaching performances and mineral dissolution behaviors of the samples. The results of nickel leaching efficiency and analysis of the solid residues suggest that all dissolved nickel originated from serpentine, which is more easily leached than goethite and talc. The rate of nickel extraction for SS ore was faster than that for SH ore. Nickel leaching from SS ore and SH ore followed the shrinking-core model and was controlled by diffusion of a reactant or product through the solid product layer.

    Suppression of pyrite oxidation in acid mine drainage by carrier microencapsulation using liquid product of hydrothermal treatment of low-rank coal, and electrochemical behavior of resultant encapsulating coatings
    © 2015 Elsevier B.V. Pyrite is a mineral sulfide found extensively in acid mine drainage; this is one of the most serious environmental problems in the mining industry. Suppression of pyrite oxidation via carrier microencapsulation (CME) with silicon (Si) and organic carriers has been proposed. In the present study, use of the hydrothermal treatment liquid (HTL) produced from low-rank coal as a carrier in CME was investigated. In dissolution tests for 51 days with pyrite and iron-oxidizing bacteria, treatment with a mixture of HTL and a silicon reagent (Si-HTL) lowered the ferric ion concentration and limited bacterial attachment compared with untreated pyrite. This might be caused by catechol present in the HTL. A mixture of catechol and a silicon reagent (Si-Cat) was also used, and the coatings obtained using Si-HTL and Si-Cat were compared. The electrochemical behavior of the treated pyrite samples showed oxidative decomposition of the Si-Cat complex and formation of an encapsulating layer at 690 mV for Si-HTL and 550 mV for Si-Cat. The two semi-circular curves in the Nyquist plot simulations showed that the total impedances of the treated pyrite samples increased. Microscopic observations showed that the oxidative layer was silica rich. These data indicate that a silica-quinone coating is created and the pyrite oxidation rate can be suppressed by pretreatment with either Si-HTL or Si-Cat for 1 h.

    Biooxidation of Gold-, Silver, and Antimony-Bearing Highly Refractory Polymetallic Sulfide Concentrates, and its Comparison with Abiotic Pretreatment Techniques
    © 2015, Copyright © Taylor & Francis Group, LLC. Effectiveness of different pure and mixed cultures of three moderately thermophilic, extremely acidophilic bacterial strains (Acidimicrobium ferrooxidans ICP, Sulfobacillus sibiricus N1, Acidithiobacillus caldus KU) were investigated for biooxidation of highly refractory polymetallic gold ore concentrates. Despite of its complex mineralogy and the presence of a mixture of potentially inhibitory metals and metalloids, the concentrate was readily dissolved in defined mixed cultures including both iron and sulfur oxidizers, releasing as much as 80% of soluble Fe and 61% of soluble As. Factors to affect microbial mineral dissolution efficiencies (i.e. microbial As(III) oxidation ability, formation of secondary mineral precipitation (e.g. jarosite, elemental sulfur, scorodite, anglesite), and microbial population dynamics during biooxidation) were studied, based on which roles of individual microbes and their synergistic interactions during biooxidation were discussed. Applying the biooxidation pretreatment using the most efficient mixed cultures containing all three strains significantly improved the recovery of both Au (from 1.1% to 86%) and Ag (from 3.2% to 87%). Finally, this study provides one of the very few available comparisons of the effectiveness of different pretreatment techniques for refractory gold ore concentrates: Compared with other abiotic pretreatment approaches (roasting, pressure oxidation, and alkali dissolution), biooxidation was shown to be one of the most effective options in terms of the recovery of Au and Ag.

    Microbial formation of crystalline scorodite for treatment of As(III)-bearing copper refinery process solution using Acidianus brierleyi
    Scorodite (FeAsO4·2H2O) is a thermodynamically stable mineral with advantages as an arsenic disposal compound. With an aim to immobilize highly toxic As(III) contained in the copper refinery process solution, eventually in the form of crystalline scorodite, the use of thermo-acidophilic iron-oxidizing archaeon, Acidianus brierleyi, was investigated. The extent of As(III) oxidation by Ac. brierleyi became greater at elevated culture As(III) concentrations, especially in the presence of yeast extract. Microbial growth on yeast extract was also implied to facilitate As(III) oxidation by Fe(III) on cell surface. When the initial Fe(II)/As(III) ratio was set at 1.4 in the presence of yeast extract, both ions were readily oxidized and 86-100% of As was precipitated as crystalline scorodite. The molar ratio of microbially-oxidized Fe(II) and As(III) was an important factor to determine the type of the secondary mineral formed. Phosphate concentration was another critical factor for scorodite biomineralization. Biogenic scorodite was crystallized with almond-shaped polyhedron habit of 1 μm in size. This study demonstrates the applicability of a one-step bioprocess which enables treatment of As(III)-bearing copper refinery process solution by producing biogenic crystalline scorodite. © 2014 Elsevier B.V.

    Microbiological contribution to the formation of the manganese deposits in Sambe hot springs, Shimane, was investigated in combination with water chemistry, characterization of sediments and microbial community structure. Analysis of bacterial and fungal community structure based on DNA extracted from a Mn-oxidizing enrichment culture indicated close matches with Pseudomonas putida, Phoma sp. and Plectosphaerella cucumerina, all Mn-oxidizing microorganisms. These sediments were poorly crystalline and formed at neutral pH values, which is characteristic of biogenic precipitates. The EPMA results demonstrated a positive correlation between Mn and Ba contents in well-crystalline Mn oxide grains. Substantial Ba contents were observed inside Mn oxide grains. These findings indicated that Ba contents in sediments are influenced by not only aqueous Ba2+ concentrations but also crystallinity of biogenic birnessite. Barium would be incorporated in birnessite during biomineralization. © 2013 The Society of Resource Geology.

    Effect of microorganisms on flocculation of quartz
    Application of microorganisms as surface modifiers in flocculation has generated a great deal of interest in recent times. The surface properties such as zeta-potential and hydrophobicity of minerals and microorganisms play a major role in determining the adsorption of microorganisms onto the minerals and hence the efficiency of flocculation. The utility of microorganisms, including Escherichia coli (wild-type and genetically modified strain Sip), Arthrobacter nicotianae, Bacillus licheniformis, and Pseudomonas maltophilia, has been evaluated by measuring their zeta-potentials and carrying out adsorption and flocculation experiments. Of the tested microorganisms, adsorption of E. coli strain Sip significantly modified the quartz surface. The zeta-potential of the quartz became highly positive at acidic pH, and its IEP (isoelectric point) was shifted from pH < 2 to pH 4.3. Moreover, the settling velocity of the bio-treated quartz reached its maximum value at this pH. The number of cells adsorbed onto quartz was low at pH above the IEP due to the identical surface charges of the mineral and bacterial cells. This led to a repulsive force between the mineral particles and bacterial cells, which hindered the adsorption process. For all of the studied strains, the settling velocity of bio-treated quartz was high at their respective IEPs. An interaction model of microorganisms is proposed to explain the flocculation behavior of bio-treated quartz. Potential energies were calculated using the DLVO theory, and the results were found to be in good agreement with the flocculation tests. The settling velocity of the bio-treated quartz was maximized at pH close to the IEP of microbial cells. Interaction between cells is identified as the most likely cause of flocculation of bio-treated quartz. © 2011 Elsevier B.V. All rights reserved.

    A rapid ATP-based method for determining active microbial populations in mineral leach liquors
    An empirical technique for the rapid assessment of active biomass of acidophilic microorganisms in pure cultures and in leach liquors from mineral bio-processing operations is described. The method is based on the measurement of ATP concentrations in test solutions, using commercially-available kits and a portable luminometer. The ATP contents of five Gram-negative biomining bacteria mineral-degrading acidophiles assayed varied from 0.87 × 10-20 to 18 × 10-20 mol per cell in actively-growing cultures. Depletion of ferrous iron in cultures of a strain of Leptospirillum ferriphilum resulted in rapid mortality of the iron-oxidizing bacterium (denoted by decreasing numbers of plate isolates) and corresponding changes in ATP concentrations in culture aliquots. The technique was applied successfully to mineral leachates from stirred tank biomining operations, where it was shown to determine populations of active microorganisms in liquors where most of the cells present were not viable. The method is highly sensitive (detecting as few as 103 acidophiles ml-1 of test solution) and would therefore have generic application in monitoring microbial populations in other types of biomining operations, such as heap bioreactors. © 2011 Elsevier B.V.

    Efficient markerless gene replacement in Corynebacterium glutamicum using a new temperature-sensitive plasmid
    Random chemical mutation of a Corynebacterium glutamicum- Escherichia coli shuttle vector derived from plasmid pCGR2 was done using hydroxylamine. It brought about amino acid substitutions G109D and E180K within the replicase superfamily domain of the plasmid's RepA protein and rendered the plasmid highly unstable, especially at higher incubation temperatures. Colony formation of C. glutamicum was consequently completely inhibited at 37°C but not at 25°C. G109 is a semi-conserved residue mutation which resulted in major temperature sensitivity. E180 on the other hand is not conserved even among RepA proteins of closely related C. glutamicum pCG1 family plasmids and its independent mutation caused relatively moderate plasmid instability. Nonetheless, simultaneous mutation of both residues was required to achieve temperature-sensitive colony formation. This new pCGR2-derived temperature-sensitive plasmid enabled highly efficient chromosomal integration in a variety of C. glutamicum wild-type strains, proving its usefulness in gene disruption studies. Based on this, an efficient markerless gene replacement system was demonstrated using a selection system incorporating the temperature-sensitive replicon and Bacillus subtilis sacB selection marker, a system hitherto not used in this bacterium. Single-crossover integrants were accurately selected by temperature-dependent manner and 93% of the colonies obtained by the subsequent sucrose selection were successful double-crossover recombinants. © 2011 Elsevier B.V.

    Effect of temperature on the bioleaching of chalcopyrite concentrates containing different concentrations of silver
    The primary copper sulfide mineral chalcopyrite (CuFeS2) is recalcitrant to both chemical and biological leaching, due to the supposed passivation of the mineral surface by sulfur and/or ferric iron compounds. Previous work has shown that addition of soluble silver can enhance solubilisation of copper from chalcopyrite by acidophilic bacteria. Silver may also be present in the concentrate itself. Here we describe the bioleaching of chalcopyrite concentrates with silver contents varying from < 1 to 1500 g/t by consortia of thirteen species of mesophilic bacteria and eleven species of moderately thermophilic acidophiles in shake flask cultures incubated at between 30 °C and 45 °C. The compositions of the microbial consortia that established in each culture were determined using a combined cultivation-based and biomolecular approach. The most effective solubilisation of copper from the 1500 and 800 g/t Ag-concentrates occurred at 30 °C, while concentrates that contained < 1 and 26 g/t of silver displayed the opposite (and predicted) pattern of mineral dissolution increasing with incubation temperature. The type strain of Acidithiobacillus ferrooxidans was the sole dominant iron-oxidising autotroph in the 800 and 1500 g/t silver concentrates, and was present in similar numbers to Leptospirillum ferrooxidans in the < 1 and 26 g/t silver concentrates, leached at 30 °C. Obligate and facultatively heterotrophic acidophiles (e.g. Acidiphilium and Gram-positive acidophiles) were also usually present, but in much smaller numbers. In contrast, at 45 °C the dominant (or sole) bacterium present at day 30 was the iron/sulfur-oxidising mixotroph Sulfobacillus thermosulfidooxidans. Sulfobacillus spp. also tended to dominate cultures incubated at 37 °C, although other bacteria, including At. ferrooxidans, were present in some mineral leachates. Highly efficient dissolution of copper (76 to > 98% over 30 days) from the 1500 g/t chalcopyrite concentrate at 30 °C was achieved using pure and mixed cultures of At. ferrooxidans. The results indicated that chalcopyrite concentrates that contain significant concentrations of silver are highly amenable to bioleaching at relatively low temperatures, using well-known acidophilic micro-organisms. © 2008 Elsevier B.V.

    Attachment of acidophilic bacteria to solid surfaces: The significance of species and strain variations
    Sixteen strains of acidophilic bacteria were screened for their abilities to adhere to pyrite ore, glass beads and ferric hydroxysulfates. These were three culture collection and two isolated strains of the iron- and sulfur-oxidizer, Acidithiobacillus ferrooxidans, two each of the sulfur-oxidizer Acidithiobacillus thiooxidans and the iron-oxidizer Leptospirillum ferrooxidans (the type strain and a mine isolate in either case), five heterotrophic acidophiles (four Acidiphilium and one Acidocella sp.) and two moderately thermophilic iron/sulfur-oxidizers (Sulfobacillus thermosulfidooxidans and Sulfobacillus acidophilus). Considerable variations were found between different species of acidophiles, and also between different strains of the same species, in how they attached to the three solid materials tested. Attachment to the solid substrata generally increased with time (over 100 min) though > 99% of one At. ferrooxidans isolate (strain OP14) were attached to pyrite after just 10 min exposure. Most acidophiles attached more readily to pyrite than to glass beads, and attachment to ferric hydroxysulfates was highly variable, though one At. ferrooxidans isolate (strain SJ2) and one heterotrophic acidophile (Acidocella sp. het-4) both attached strongly to ferric iron precipitates (jarosites and schwertmannite) that formed in cultures of At. ferrooxidans grown at pH > 2. The results of these experiments showed that even closely related strains of acidophilic bacteria can display very different propensities to attach to solid materials, an observation that may explain the somewhat disparate results reported on occasions by research groups that have examined single, or limited numbers of strains, of acidophiles (mostly At. ferrooxidans). The significance of differential attachment of mineral-oxidizing and other acidophiles to pyrite and other solids is discussed in the context of biohydrometallurgy. © 2006 Elsevier B.V.

    © 2015 Elsevier Ltd. All rights reserved. Comparison effect of chemical citric acid and other leaching reagents including inorganic acid and other organic acid on nickel extraction from low-grade Indonesian saprolitic ores was evaluated. Two saprolitic ores from two different mining areas (Sulawesi Island and Halmahera Island) in Indonesia were used to investigate the leaching performance and mineral dissolution behaviors of different ore samples using different leaching reagents. Leaching was performed using citric, sulfuric, nitric, hydrochloric, lactic, and oxalic acids. The saprolitic ore from Sulawesi Island (SS) has higher serpentine and lower goethite contents than the saprolitic ore from Halmahera Island (SH). These differences significantly affect the leaching performances and metal dissolution behaviors. Citric acid and sulfuric acid were more effective than other acid solutions for nickel extraction from both samples. Citric acid was very effective for dissolving nickel from serpentine, but did not recover nickel from goethite. In contrast, inorganic acids, namely sulfuric, nitric, and hydrochloric acids, can extract nickel from lateritic ores by dissolving goethite as well as serpentine, but the nickel recoveries achieved with sulfuric acid were higher than those achieved with other inorganic acids. A comparison of the leaching performances of the two samples shows that nickel recovery from SS was higher than that from SH when citric acid leaching was used, but the samples gave similar nickel recoveries in all inorganic acid and lactic acid leaching processes. Moreover, oxalic acid is the least effective reagent for nickel extraction from both samples, because of nickel oxalate precipitation after nickel dissolution. In addition, the effect of a sulfuric acid-citric acid mixture on the nickel dissolution rate was investigated to confirm the individual influences of citric acid and sulfuric acid on the leaching behavior of each sample. The results show that an increase in the amount of sulfuric acid affected the dissolution rate of nickel in leaching of SH much more than that in leaching of SS. In general, the effect of citric acid in the mixture of sulfuric acid and citric acid is attractive. Moreover, citric acid offers not only high nickel recovery and high selectivity of leaching but also an environmentally safe process and low acid consumption.
