Impact of Molecular Hydrogen on Chalcopyrite Bioleaching by the Extremely Thermoacidophilic Archaeon Metallosphaera sedula
APPLIED AND ENVIRONMENTAL MICROBIOLOGY, 76(8), 2668–2672.
MeSH headings : Archaeal Proteins / biosynthesis; Copper / metabolism; Electron Transport Chain Complex Proteins / biosynthesis; Gene Expression Profiling; Hydrogen / metabolism; Sulfolobaceae / metabolism
TL;DR:
Hydrogen served as a competitive inorganic energy source, impacting the CuFeS2 bioleaching efficiency of the extremely thermoacidophilic archaeon Metallosphaera sedula, and open reading frames encoding key terminal oxidase and electron transport chain components were triggered by Cu FeS2.

Physiological Versatility of the Extremely Thermoacidophilic Archaeon Metallosphaera sedula Supported by Transcriptomic Analysis of Heterotrophic, Autotrophic, and Mixotrophic Growth
APPLIED AND ENVIRONMENTAL MICROBIOLOGY, 76(3), 931–935.
MeSH headings : Aerobiosis / genetics; Archaeal Proteins / genetics; Archaeal Proteins / metabolism; Autotrophic Processes; Carbon Dioxide / metabolism; Carbon Isotopes; Gene Expression Profiling; Gene Expression Regulation, Archaeal; Heterotrophic Processes; Hot Temperature; Hydroxybutyrates / metabolism; Oligonucleotide Array Sequence Analysis; Substrate Specificity / genetics; Sulfolobaceae / genetics; Sulfolobaceae / growth & development; Sulfolobaceae / metabolism; Temperature
TL;DR:
Comparative transcriptomic analysis of autotroph, heterotrophic, and mixotrophic growth of the archaeon Metallosphaera sedula revealed candidates for yet-to-be-confirmed components of the 3-hydroxypropionate/4-Hydroxybutyrate pathway and implicated a membrane-bound hydrogenase for growth on H2.

Identification of Components of Electron Transport Chains in the Extremely Thermoacidophilic Crenarchaeon Metallosphaera sedula through Iron and Sulfur Compound Oxidation Transcriptomes
APPLIED AND ENVIRONMENTAL MICROBIOLOGY, 74(24), 7723–7732.
MeSH headings : Archaeal Proteins / biosynthesis; Archaeal Proteins / genetics; Electron Transport Chain Complex Proteins / biosynthesis; Electron Transport Chain Complex Proteins / genetics; Ferrous Compounds / metabolism; Gene Expression Profiling; Genes, Archaeal; Iron-Sulfur Proteins / biosynthesis; Iron-Sulfur Proteins / genetics; Multigene Family; Oxidation-Reduction; Oxidoreductases / biosynthesis; Oxidoreductases / genetics; Sulfolobaceae / enzymology; Sulfolobaceae / genetics; Sulfolobaceae / metabolism; Sulfur / metabolism
TL;DR:
From this analysis, a comprehensive model for electron transport in M. sedula could be proposed as the basis for examining specific details of iron and sulfur oxidation in this bioleaching archaeon.

2007 journal article
The genome sequence of the metal-mobilizing, extremely thermoacidophilic archaeon Metallosphaera sedula provides insights into bioleaching-associated metabolism
APPLIED AND ENVIRONMENTAL MICROBIOLOGY, 74(3), 682–692.
MeSH headings : Amino Acid Sequence; Archaeal Proteins / genetics; Archaeal Proteins / metabolism; Gene Expression Regulation, Archaeal; Genome, Archaeal; Hot Temperature; Iron / metabolism; Molecular Sequence Data; Oligonucleotide Array Sequence Analysis; Oxidation-Reduction; Sequence Analysis, DNA; Sulfates / metabolism; Sulfolobaceae / classification; Sulfolobaceae / genetics; Sulfolobaceae / metabolism
TL;DR:
Comparisons with the mesophilic biomining bacterium Acidithiobacillus ferrooxidans indicate that the M. sedula genome encodes at least one putative rusticyanin, involved in iron oxidation, and a putative tetrathionate hydrolase, implicated in sulfur oxidation, which is a desirable trait of biomining microorganisms.
