Abstract
A novel acidophilic, aerobic bacterium strain, MYW30-H2T, was isolated from a heap of polymetallic mine. Cells of strain MYW30-H2T were Gram-stain-positive, endospore-forming, motile, and rod-shaped. Strain MYW30-H2T grew at a temperature range of 30-45 °C (optimum 40 °C) and a pH range of 3.5-6.0 (optimum 4.0) in the presence of 0-0.5% (w/v) NaCl. Strain MYW30-H2T could grow heterotrophically on yeast extract and glucose, and grow mixotrophically using ferrous iron as an electron donor with yeast extract. Menaquinone-7 (MK-7) was the sole respiratory quinone of the strain. Iso-C15:0 and anteiso-C15:0 were the major cellular fatty acids. The 16S rRNA gene sequence analysis showed that MYW30-H2T was phylogenetically affiliated with the family Alicyclobacillaceae, and the sequence similarity with other Alicyclobacillaceae genera species was below 91.51%. The average amino acid identity value of the strain with its phylogenetically related species was 52.3-62.1%, which fell into the genus boundary range. The DNA G+C content of the strain was 44.2%. Based on physiological and phylogenetic analyses, strain MYW30-H2T represents a novel species of a new genus of the family Alicyclobacillaceae, for which the name Fodinisporobacter ferrooxydans gen. nov., sp. nov. is proposed. The type strain is MYW30-H2T (=CGMCC 1.17422T = KCTC 43278T).

Abstract
Alicyclobacillus sp. DSM 11985T was isolated from geothermal soil but had not yet been classified at the species level. The strain produced guaiacol, which is of interest from the viewpoint of food spoilage in the food industry. 16S rRNA gene sequence analysis revealed that strain DSM 11985T was closely related (99.6 % similarity) to Alicyclobacillus hesperidum DSM 12489T. However, strains of A. hesperidum did not produce guaiacol; therefore, we performed the taxonomic characterization of strain DSM 11985T. The results showed that strain DSM 11985T and strains of A. hesperidum showed different phenotypic characteristics in biochemical/physiological tests including guaiacol production. Average nucleotide identity values between strain DSM 11985T and strain DSM 12489T were 95.4-95.9 %, and the in silico DNA-DNA hybridization value using the Genome-to-Genome Distance Calculator between strains DSM 11985T and DSM 12489T was 65.5 %. These values showed that strain DSM 11985T was genetically closely related but separated from strains of A. heparidum. From the above results, a novel subspecies of A. hesperidum, named Alicyclobacillus hesperidum subsp. aegles subsp. nov. is proposed. The type strain is DSM 11985T (=FR-12T=NBRC 113041T).

Abstract
Six thermo-acidophilic, spore-forming strains were isolated from a variety of juice products and were characterized genetically and phenotypically. According to 16S rRNA and rpoB gene phylogenetic analyses and average nucleotide identity comparisons against the species demarcation cutoff at <95 %, these six strains were determined to represent three novel species of Alicyclobacillus. The isolates were designated FSL-W10-0018T, FSL-W10-0037, FSL-W10-0048, VF-FSL-W10-0049T, FSL-W10-0057 and FSL-W10-0059T. All six isolates were Gram-positive, motile, rod shaped, contained menaquinone 7 as the major respiratory quinone and had ω-cyclohexane C17 : 0 as a major fatty acid. They were all able to grow aerobically in a range of acidic and moderate thermal conditions. Only isolates FSL-W10-0048 and VF-FSL-W10-0049T were able to produce guaiacol. The following names are proposed for the three new species: Alicyclobacillus mali sp. nov. (type strain FSL-W10-0018T =DSM 112016T=NCIMB 15266T); Alicyclobacillus suci sp. nov (VF-FSL-W10-0049T=DSM 112017T=NCIMB 15265T); and Alicyclobacillus fructus sp. nov. (FSL-W10-0059T=DSM 112018T=NCIMB 15264T).

Abstract
The term extremophile was suggested more than 30 years ago and represents microorganisms that are capable of developing and living under extreme conditions, these conditions being particularly hostile to other types of microorganisms and to humankind. In terrestrial hydrothermal sites, like hot springs, "mud pools", solfataras, and geysers, the dominant extreme conditions are high temperature, low or high pH, and high levels of salinity. The diversity of microorganisms inhabiting these sites is determined by the conditions of the environment. Organisms belonging to the domains Archaea and Bacteria are more represented than the one belonging to Eukarya. Eukarya members tend to be less present because of their lower tolerance to higher temperatures, however, they perform important ecosystem processes when present. Both prokaryotes and eukaryotes have morphological and physical adaptations that allow them to colonize extreme environments. Microbial mats are complex associations of microorganisms that help the colonization of more extreme systems. In this review, a characterization of prokaryotic and eukaryotic organisms that populate terrestrial hydrothermal systems are made.

Abstract
Thermoacidophilic Alicyclobacillus strains attract great interests as the resource of thermostable or acidic enzymes. In this study, a putative gene encoding superoxide dismutase (AaSOD) was identified in a thermoacidophilic Alicyclobacillus strain. With a 16-fold activity observed, the AaSOD activity expressing in the medium of manganese enrichment was much higher than that in the iron medium. In addition, the purified AaSOD can be reconstituted exclusively with either Fe2+ or Mn2+, with its Mn-bound protein showing 25-fold activity than that of Fe-bound form. The optimal temperature for AaSOD reaction was 35°C, and was highly stable at any certain temperature up to 80°C. Of particular interest, the enzyme is found to be very stable across a wide pH range spanning from 2.0 to 10.0, which confers its robust stability in the acidic stomach environment and implies striking potentials as food additive and for medical use.

Abstract
Alicyclobacillus acidoterrestris is a spore-forming bacterium of importance to the fruit juice industry due to its remarkable heat resistance and production of guaiacol taint. Whole genome sequencing analysis reveals species demarcation corresponds to the two major genotypic groups to which A. acidoterrestris isolates belong. Heat resistance was significantly different between genotypic groups 1 and 2 with D90 values of 15.5 and 9.3 min, respectively (p < 0.01). Comparison of squalene-hopene cyclase (shc) encoding sequences reveals non-synonymous changes and the alteration of glutamine residues. Glutamine absence may link to the stability reinforcement of the enzyme structure against thermal denaturation. Genomic islands harbouring heavy metal resistance genes are found in the majority of genotypic group 1 genomes (63%) but occurs in only one genome (5%) of genotypic group 2. Distribution of the genomic islands in the genotypic groups 1 and 2 is also consistent with phylogenetic trees and ANI and dDDH values. Subsequently, we propose genotypic group 1 as a new species closely related to A. acidoterrestris that possesses enhanced heat resistance.

Abstract
Three morphologically similar thermo-acidophilic strains, USBA-GBX-501, USBA-GBX-502 and USBA-GBX-503T, were isolated from acidic thermal springs at the National Natural Park Los Nevados (Colombia). All isolates were spore-forming, Gram-stain-positive and motile, growing aerobically at 25-55 °C (optimum ~45 °C) and at pH 1.5-4.5 (optimum pH ~3.0). Phylogenetic analysis of the 16S rRNA gene sequences of these isolates showed an almost identical sequence (99.0 % similarity) and they formed a robust cluster with the closest relative Alicyclobacillus tolerans DSM 16297T with a sequence similarity of 99.0 %. Average similarity to other species of the genus Alicyclobacillus was 93.0 % and average similarity to species of the genus Effusibacillus was 90 %. In addition, the level of DNA-DNA hybridization between strain USBA-GBX-503T and Alicyclobacillus tolerans DSM 16297T was 31.7 %. The genomic DNA G+C content of strain USBA-GBX-503T was 44.6 mol%. The only menaquinone was MK-7 (100.0 %). No ω-alicyclic fatty acids were detected in strain USBA-GBX-503T, and the major cellular fatty acids were C18 : 1ω7c, anteiso-C17 : 0 and iso-C17 : 0. Based on phenotypic and chemotaxonomic characteristics, phylogenetic analysis and DNA-DNA relatedness values, along with low levels of identity at the whole genome level (ANIb and ANIm values of <67.0 and <91.0 %, respectively), it can be concluded that strain USBA-GBX-503T represents a novel species of the genus Alicyclobacillus, for which the name Alicyclobacillus montanus sp. nov. is proposed. The type strain is USBA-GBX-503T (=CMPUJ UGB U503T=CBMAI1927T).
