“…A similar result was obtained from the analysis of the chemical assays on pyrite dissolution [by iron(III) ions]. This finding clearly indicates the lack of enzymes for sulfur compound oxidation in L. ferrooxidans (in contrast to the data of Sugio et al [33]). Thus, the functions of these two leaching bacteria are (i) to supply iron(III) ions (complexed in the exopolymer layer) for an attack on the pyrite lattice and (ii) to keep the iron ions in the oxidized iron(III) species.…”

In the case of pyrite bioleaching by Leptospirillum ferrooxidans, an organism without sulfur-oxidizing capacity, besides the production of tetra-and pentathionate, a considerable accumulation of elemental sulfur occurred. A similar result was obtained for chemical oxidation assays with acidic, sterile iron(III) ioncontaining solutions. In the case of Thiobacillus ferrooxidans, only slight amounts of elemental sulfur were detectable because of the organism's capacity to oxidize sulfur compounds. In the course of oxidative, chemical pyrite degradation under alkaline conditions, the accumulation of tetrathionate, trithionate, and thiosulfate occurred. The data indicate that thiosulfate, trithionate, tetrathionate, and disulfane-monosulfonic acid are key intermediate sulfur compounds in oxidative pyrite degradation. A novel (cyclic) leaching mechanism is proposed which basically is indirect.

“…It is oxidized in the presence of heavy metal cations to sulfate (as well as traces of sulfur dioxide gas). Possibly T. ferrooxidans is participating in this reaction since this bacterium possesses a sulfite oxidase (20,32,33). Obviously, all these reactions occur in the direct vicinity of the pyrite surface.…”

“…Sampel yang menunjukkan hasil positif yaitu L3K, L3B, L2B, L1B, dan L1K yang ditandai dengan perubahan warna medium menjadi kuning kecoklatan atau kuning karat yang mengindikasikan adanya pertumbuhan bakteri besi dan sulfur pada sampel tanah. Hal ini disebabkan terbentuknya besi ferri (Fe 3+ ) karena dioksidasinya besi ferro (Fe 2+ ) oleh bakteri pengoksidasi besi (Untung, 1999; Sugio et al, 1994; Erskini dan Budiyanto, 1994; Brock and Michael, 1991.

Heavy metals contamination disturb balance and diversity of microorganism in soil. Microorganisms which can able to survive in those conditions are bacteria capable of oxidizing heavy metals. Identification based on 16S rRNA was used to determine characteristics and phylogenetic relationship of bacteria which can oxidize iron and sulphur in tin mining areas. The aim of this research was able to determine the bacterias characteristics isolated from tin mining areas and determine the phylogenetic relation of iron-sulphur oxidizing bacteria on tin mining soil in Belitung based on 16S rRNA sequences. This research was done using descriptive method, including isolation, morphological characterization, and identification based on 16S rRNA sequences. Morphology characterization includes colony and cell morphology through Gram staining. Molecular characterization includes amplification of 16S rRNA gene (Polymerase Chain Reaction/ PCR), electrophoresis amplicon and sequencing. Bacteria identification was done by comparing the 16S rRNA gene sequence in GenBank. The result showed three bacterias were identified by 16S rRNA have a similarity with Bacillus anthracis strain Ames, Bacillus cereus ATCC 14579, Staphylococcus sciuri subsp. Sciuri strains DSM 20345 and Micrococcus luteus NCTC 2665.

“…This relationship may be attributable to the coupled redox cycling of iron and nitrogen. For example, some members of the dominant genera Pseudomonas and Thiobacillus (e.g., Pseudomonas stutzeri, Thiobacillus ferrooxidans) are also known to be capable of nitrate-dependent Fe(II) oxidation (Coby et al 2011;Straub et al 1996;Sugio et al 1994). Some Geobacter species are also capable of nitrate-reducing Fe(II) oxidation with the reduction of NO 3 − to NH 4 + (Coby et al 2011;Weber et al 2006b).…”

Rivers are the primary contributors of iron and other elements to the global oceans. Iron-reducing bacteria play an important biogeochemical role in coupling the iron and carbon redox cycles. However, the extent of changes in community structures and iron-reduction activities of iron-reducing bacteria in riverine and coastal marine sediments remains unclear. This study presents information on the spatial patterns and relative abundance of iron-reducing bacteria in sediments of the Yellow River estuary and the adjacent Bohai Sea. High-throughput sequencing of bacterial 16S rRNA found that the highest relative abundances and diversities were from the estuary (Yellow River-Bohai Sea mixing zone). Pseudomonas, Thiobacillus, Geobacter, Rhodoferax, and Clostridium were the most abundant putative iron-reducing bacteria genera in the sediments of the Yellow River. Vibrio, Shewanella, and Thiobacillus were the most abundant in the sediments of the Bohai Sea. The putative iron-reducing bacterial community was positively correlated with the concentrations of total nitrogen and ammonium in coastal marine sediments, and was significantly correlated with the concentration of nitrate in river sediments. The riverine sediments, with a more diverse iron-reducing bacterial community, exhibited increased activity of Fe(III) reduction in enrichment cultures. The estuary-wide high abundance of putative iron-reducing bacteria suggests that the effect of river-sea interaction on bacterial distribution patterns is high. The results of this study will help the understanding of the biogeochemical cycling of iron in riverine and coastal marine environments.
