Abstract:
The ‘iron bacteria’ are a collection of morphologically and phylogenetically heterogeneous prokaryotes. They include some of the first micro-organisms to be observed and described, and continue to be the subject of a considerable body of fundamental and applied microbiological research. While species of iron-oxidizing bacteria can be found in many different phyla, most are affiliated with the Proteobacteria. The latter can be subdivided into four main physiological groups: (i) acidophilic, aerobic iron oxidizers; (ii) neutrophilic, aerobic iron oxidizers; (iii) neutrophilic, anaerobic (nitrate

Abstract:
An understanding of the physiology and metabolic complexity of microbial consortia involved in metal solubilization is a prerequisite for the rational improvement of bioleaching technologies. Among the most challenging aspects that remain to be addressed is how aerobic acidophiles, especially Fe(II)-oxidizers, contend with the paradoxical hazards of iron overload and iron deficiency, each with deleterious consequences for growth. Homeostatic mechanisms regulating the acquisition, utilization/oxidation, storage and intracellular mobilization of cellular iron are deemed to be critical for fitnes

Abstract:
Iron-oxidizing autotrophs (mainly Thiobacillus ferrooxidans) and acidophilic heterotrophs were recovered and quantified at an incubation temperature of 18 °C, in four tailings-effluent samples obtained from the environment of a uranium mine in Ontario, Canada. The samples were collected during winter when the temperatures of the effluents were in the range 0.5–5.0 °C. Iron-oxidizing autotrophs were recovered in the four samples and their numbers ranged from 3 ± 2 to 185 ± 18 colony-forming units/mL; acidophilic heterotrophs were recovered in three of the four samples and their numbers ranged f

Abstract:
Acidiphilium multivorum LMS is an acidophile isolated from industrial bioreactors during the processing of the gold-bearing pyrite-arsenopyrite concentrate at 38–42 °C. Most strains of this species are obligate organoheterotrophs that do not use ferrous iron or reduced sulfur compounds as energy sources. However, the LMS strain was identified as one of the predominant sulfur oxidizers in acidophilic microbial consortia. In addition to efficient growth under strictly heterotrophic conditions, the LMS strain proved to be an active sulfur oxidizer both in the presence or absence of organic compou

Abstract:
Iron-oxidizing autotrophs and acidophilic heterotrophs were quantified at an incubation temperature of 18 °C in several samples obtained from the bioleaching areas of two uranium mines in Ontario, Canada. All samples were mine-water samples with temperatures in the range 13–18 °C. Iron-oxidizing autotrophs ranged from 2683 ± 377 to 245 000 ± 20 205 colony-forming units∙mL−1 and were always numerically superior to acidophilic heterotrophs, which ranged from 40 ± 8 to 9650 ± 161 colony-forming units∙mL−1.

Abstract:
More than 100 cultures of acidophilic Fe(II)- and/or sulfur-oxidizing microorganisms from mine waste dumps in 10 different countries all over the world have been maintained in liquid media in the BGR-strain collection for many years. Our 16S rDNA analysis showed that most of the cultivated Fe(II)-oxidizers belong to four genera: Acidithiobacillus, Acidimicrobium, “Ferrimicrobium” and Leptospirillum. All analyzed Acidithiobacillus strains were identified as At. ferrooxidans. The Leptospirillum strains were affiliated with L. ferriphilum or L. ferrooxidans. The Gram-positive strains related to A

Abstract:
Microbial communities of iron-rich water in the Pyhäsalmi mine, Finland, were investigated with high-throughput amplicon sequencing and qPCR targeting bacteria, archaea, and fungi. In addition, the abundance ofLeptospirillumandAcidithiobacilluswas assessed with genus-specific qPCR assays, and enrichment cultures targeting aerobic ferrous iron oxidizers and ferric iron reducers were established. The acidic (pH 1.4–2.3) mine water collected from 240 m, 500 m, and 600 m depth from within the mine had a high microbial diversity consisting of 63-114 bacterial, 10-13 archaeal, and 104-117 fungal gen

Abstract:
The family Acidiferrobacteraceae (order Acidiferrobacterales) currently contains three genera of chemolithoautotrophs: Sulfuricaulis (2016), Sulfurifustis (2015) and Acidiferrobacter (2011). While the two former are neutrophilic sulfur oxidizers isolated from lake sediments in Japan, the latter is an extremely acidophilic, moderately osmophilic, thermotolerant iron/sulfur oxidizer known to occur in macroscopic streamers in Rio Tinto, Spain and in acid waters worldwide. The type strains of both Sulfuricaulis limnicola (HA5T) and Sulfurifustis variabilis (skN76T) have been sequenced, and the dra

ABSTRACT The microbial composition of acid streamers (macroscopic biofilms) in acidic, metal-rich waters in two locations (an abandoned copper mine and a chalybeate spa) in north Wales was studied using cultivation-based and biomolecular techniques. Known chemolithotrophic and heterotrophic acidophiles were readily isolated from disrupted streamers, but they accounted for only <1 to 7% of the total microorganisms present. Fluorescent in situ hybridization (FISH) revealed that 80 to 90% of the microbes in both types of streamers were β-Proteobacteria. Terminal restriction fragment length pol

Abstract:
Acidophilic iron oxidizing bacteria of the betaproteobacterial genus “Ferrovum” are ubiquitously distributed in acid mine drainage (AMD) habitats worldwide. Since their isolation and maintenance in the laboratory has proved to be extremely difficult, members of this genus are not accessible to a “classical” microbiological characterization with exception of the designated type strain “Ferrovum myxofaciens” P3G. The present study reports the characterization of “Ferrovum” strains at genome and transcriptome level. “Ferrovum” sp. JA12, “Ferrovum” sp. PN-J185 and “F. myxofaciens” Z-31 represent t
