The order Acidithiobacillales was previously assigned to the class Gammaproteobacteria. Recent analyses have indicated that this order actually lies outside all the proteobacterial classes, as a sister group to the combined classes Betaproteobacteria and Gammaproteobacteria. We now confirm this result with multiprotein phylogenetic analysis of all the available genomes of members of the order Acidithiobacillales and representatives of all available bacterial orders, and propose the new… 

Definitive assignment by multigenome analysis of the gammaproteobacterial genus Thermithiobacillus to the class Acidithiobacillia.

Preliminary phylogenetic assessment of the genome sequence of Thermithiobacillus tepidarius in 2013 has enabled phylogenetics assessment of this organism by comparative multigenome analysis, and shows definitively that Thermitho bacillus is a member of the class AcidithiOBacillia, distinct from the Acidithuobacilli genus.

Genomic evolution of the class Acidithiobacillia: deep-branching Proteobacteria living in extreme acidic conditions

This work provides the most comprehensive classification and pangenomic analysis of this deep-branching class of Proteobacteria to date and illuminates not only the evolutionary past of this lineage, but also the molecular evolution of relevant aerobic respiratory proteins, namely the cytochrome bo3 ubiquinol oxidases.

A report of 46 unrecorded bacterial species in Korea belonging to the classes Alphaproteobacteria, Betaproteobacteria, Deltaproteobacteria and Epsilonproteobacteria

At the time of writing, the taxonomic classification based on 16S rRNA sequences shows the class Alphaproteobacteria includes 15 orders: Caulobacterales, Emcibacterale, Iodidimonadales, Kiloniellales, Kordiimonadale, Magnetococcales, Micropepsales, Parvularculales, Pe.

Oligoflexia, the Newest Class of the Phylum Proteobacteria, Consisting of only One Cultured Species and Uncultured Bacterial Phylotypes from Diverse Habitats

It is suggested that members of Oligoflexia may display cosmopolite distribution in general as well as endemism in certain geochemical settings.

Phylogenomics of the Phylum Proteobacteria: Resolving the Complex Relationships.

From the results, it is concluded that concatenated trees of conserved proteins are a more accurate method for phylogenetic analysis, as compared to other methods used.

Reclassification of 'Thiobacillus prosperus' Huber and Stetter 1989 as Acidihalobacter prosperus gen. nov., sp. nov., a member of the family Ectothiorhodospiraceae.

It is shown that 'Thiobacillus prosperus' DSM 5130 belongs to a new genus within the family Ectothiorhodospiraceae, for which it is proposed to be named Acidihalobacter prosperus, and that it becomes the type strain of the type species of this genus.

Taxonomic hierarchy of the phylum Proteobacteria and Korean indigenous novel Proteobacteria species

The present work aimed to elucidate the chronological process of establishing a taxonomic hierarchy for the Journal of Species Research 8(2):197-214, 2019.

Draft genome sequence of the type strain of the sulfur-oxidizing acidophile, Acidithiobacillus albertensis (DSM 14366)

The draft genome sequence of Acidithiobacillus albertensis DSM 14366T is presented, thereby both filling a long-standing gap in the genomics of the acidithiabacilli, and providing further insight into the understanding of the biology of the non iron-oxidizing members of the Acidith iobacilli genus.

Complete genome sequence of Enterobacter sp. IIT-BT 08: A potential microbial strain for high rate hydrogen production

The specific properties of the organism and the generation, annotation and analysis of its genome sequence as well as the putative pathway of hydrogen production by this organism are described.

Integrative Genomics Sheds Light on Evolutionary Forces Shaping the Acidithiobacillia Class Acidophilic Lifestyle

Gain of genes such as hopanoid biosynthesis involved in membrane stabilization at low pH and the functional redundancy for generating an internal positive membrane potential revealed the transition from neutrophilic properties to a new acidophilic lifestyle by shaping the Acidithiobacillaceae genomic structure.

On the basis of physiological characters and 16S rRNA gene sequence comparisons, eight of the existing Thiobacillus species are proposed for reassignment to three newly designated genera within the gamma-subclass of the Proteobacteria.

The phylogeny of purple bacteria: the alpha subdivision.

Phylogeny of Gammaproteobacteria

A telescoping multiprotein approach is applied to the phylogeny of the large bacterial class Gammaproteobacteria, based on a set of 356 protein families for the whole class and even larger sets for each of four cohesive subregions of the tree.

A Robust Species Tree for the Alphaproteobacteria

Pelagibacter genes will serve as useful additions to the bacterial outgroup in future evolutionary studies of mitochondrial genes, including those that have transferred to the eukaryotic nucleus.

Evolutionary relationships among sulfur- and iron-oxidizing eubacteria

A picture is emerging of an evolutionary widespread capacity for sulfur and/or iron oxidation among the eubacteria, with three unnamed facultatively thermophilic iron-oxidizing isolates exhibiting no clear phylum level affiliation at all.

Acidithiobacillus ferrivorans, sp. nov.; facultatively anaerobic, psychrotolerant iron-, and sulfur-oxidizing acidophiles isolated from metal mine-impacted environments

Phenotypic and genotypic analysis was carried out on four iron- and sulfur-oxidizing acidophilic bacteria isolated from different parts of the world, and it appears that the bacteria of the NO-37 group have a different biochemical mechanism for oxidizing ferrous iron than At.

Acidithiobacillales ord. nov.

The order Acidithiobacillales was circumscribed for this volume on the basis of phylogenetic analysis of 16S rDNA sequences; the order contains the families Acidithiobacillaceae and

A Novel Lineage of Proteobacteria Involved in Formation of Marine Fe-Oxidizing Microbial Mat Communities

On the basis of phylogenetic and physiological data, it is proposed that isolate PV-1T ( = ATCC BAA-1019: JCM 14766) represents the type strain of a novel species in a new genus, Mariprofundus ferrooxydans gen. nov.

Biodiversity and Emerging Biogeography of the Neutrophilic Iron-Oxidizing Zetaproteobacteria

Assessment of the biodiversity of this burgeoning class of the Proteobacteria and analysis of molecular variance showed that geographic distance played a significant role in the distribution of Zetaproteobacteria biodiversity, whereas environmental parameters did not have a significant effect.

Acidiferrobacter thiooxydans, gen. nov. sp. nov.; an acidophilic, thermo-tolerant, facultatively anaerobic iron- and sulfur-oxidizer of the family Ectothiorhodospiraceae

Strain m-1 is proposed as the type strain of a new genus and species of bacteria, Acidiferrobacter thiooxydans, which is a moderate osmophile and shown to be diazotrophic and tolerant of elevated concentrations of many metals typically found in mine-impacted environments.
