“…Bands 3 (1) and 13 belonged to the genera Geobacillus and Anoxybacillus , respectively, which grow under aerobic conditions, are heterotrophic and can reduce nitrate (Poli et al, 2006; Inan et al, 2013). These species were inferred to dominate the aerobic denitrification.…”

Microbial fuel cells (MFCs) have attracted much attention due to their ability to generate electricity while treating wastewater. The performance of a double-chamber MFC with simultaneous nitrification and denitrification (SND) in the cathode for treating synthetic high concentration ammonia wastewater was investigated at different dissolved oxygen (DO) concentrations and high temperatures. The results showed that electrode denitrification and traditional heterotrophic denitrification co-existed in the cathode chamber. Electrode denitrification by aerobic denitrification bacterium (ADB) is beneficial for achieving a higher voltage of the MFC at high DO concentrations (3.0–4.2 mg/L), while traditional heterotrophic denitrification is conducive to higher total nitrogen (TN) removal at low DO (0.5–1.0 mg/L) concentrations. Under high DO conditions, the nitrous oxide production and TN removal efficiency were higher with a 50 Ω external resistance than with a 100 Ω resistance, which demonstrated that electrode denitrification by ADB occurred in the cathode of the MFC. Sufficient electrons were inferred to be provided by the electrode to allow ADB survival at low carbon:nitrogen ratios (≤0.3). Polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) results showed that increasing the DO resulted in a change of the predominant species from thermophilic autotrophic nitrifiers and facultative heterotrophic denitrifiers at low DO concentrations to thermophilic ADB at high DO concentrations. The predominant phylum changed from Firmicutes to Proteobacteria, and the predominant class changed from Bacilli to Alpha, Beta, and Gamma Proteobacteria.

“…The respiratory menaquinones found were MK-8 (92 %) and MK-7 (5 %). These appear also to be characteristic of strain GSsed3 T compared with other species of the genus Anoxybacillus for which the information is available and that had as major respiratory menaquinone MK-7 (Cihan et al, 2011(Cihan et al, , 2014Coorevits et al, 2012;Gul-Guven et al, 2008;Inan et al, 2013). The total hydrolysate (4 M HCl, 16 h at 100 C) of the peptidoglycan contained the amino acids meso-diaminopimelic acid (meso-Dpm), alanine (Ala) and glutamic acid (Glu).…”

“…Besides the phenotypic similarities, species that belong to the genus Anoxybacillus share common ecological characteristics, too. All of them are thermophiles or moderate thermophiles, with the majority of the species isolated so far originating from thermal springs (Atanassova et al, 2008;Belduz et al, 2003;Cihan et al, 2011Cihan et al, , 2014Dai et al, 2011;Derekova et al, 2007;Dulger et al, 2004;Inan et al, 2013;Poli et al, 2009;Yumoto et al, 2004;Zhang et al, 2011Zhang et al, , 2013. The aim of this study was to describe a novel species of the genus Anoxybacillus isolated from a geothermal reservoir.…”

“…The name given to the genus suggests that species assigned to it thrive under anoxic conditions, and, indeed, the first species classified as members of the genus Anoxybacillus were aerotolerant anaerobes (Pikuta et al, 2000). Nevertheless, at the time of writing, from the 22 species of the genus Anoxybacillus, 16 are facultative anaerobes (Atanassova et al, 2008;Belduz et al, 2003;Cihan et al, 2011Cihan et al, , 2014Dai et al, 2011;De Clerck et al, 2004;Dulger et al, 2004;Kevbrin et al, 2005;Namsaraev et al, 2010;Poli et al, 2006;Schaffer et al, 2004;Yumoto et al, 2004;Zhang et al, 2011), five are strict aerobes (Coorevits et al, 2012;Derekova et al, 2007;Inan et al, 2013;Poli et al, 2009;Zhang et al, 2013) and one is an aerotolerant anaerobe (Pikuta et al, 2000). Species that belong to the genus Anoxybacillus share common characteristics, mainly concerning their major fatty acids (iso-C 17 : 0 and iso-C 15 : 0 ), the rod shape of the vegetative cells and the terminal/subterminal position of their endospores.…”

A novel endospore-forming bacterium designated strain GSsed3 T was isolated from deposits clogging aboveground filters from the geothermal power platform of Groß Schönebeck in northern Germany. The novel isolate was Gram-staining-positive, facultatively anaerobic, catalase-positive and oxidase-positive. Optimum growth occurred at 60 C, 0.5 % (w/v) NaCl and pH 7-8. Analysis of the 16S rRNA gene sequence similarity indicated that strain GSsed3 T belonged to the genus Anoxybacillus, and showed 99.8 % sequence similarity to Anoxybacillus rupiensis R270 T , 98.2 % similarity to Anoxybacillus tepidamans GS5-97 T , 97.9 % similarity to Anoxybacillus voinovskiensis TH13 T , 97.7 % similarity to Anoxybacillus caldiproteolyticus DSM 15730 T and 97.6 % similarity to Anoxybacillus amylolyticus MR3C T . DNA-DNA hybridization (DDH) indicated only 16 % relatedness to Anoxybacillus rupiensis DSM 17127 T . Furthermore, DDH estimation based on genomes analysis indicated only 19.9 % overall nucleotide similarity to Anoxybacillus amylolyticus DSM 15939 T . The major respiratory menaquinone was MK-8. The polar lipid profile consisted of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, one unknown phosphoglycolipid and one unknown phospholipid. The predominant cellular fatty acids were iso-C 15 : 0 , iso-C 17 : 0 , C 16 : 0 , iso-C 16 : 0 and anteiso-C 17 : 0 . The peptidoglycan type was A1g meso-Dpm-direct. The genomic DNA G+C content of the strain was 46.9 mol%. The phenotypic, genotypic and chemotaxonomic characterization indicated that strain GSsed3 T differs from related species of the genus. Therefore, strain GSsed3 T is considered to be a representative of a novel species of the genus Anoxybacillus, for which the name Anoxybacillus geothermalis sp. nov. is proposed. The type strain of Anoxybacillus geothermalis is GSsed3 T (=CCOS808 T =ATCC BAA2555 T ).

Four closely related facultative anaerobe, moderately thermophilic, Gram positive rods (JS1T, JS5, JS11, and JS15) were isolated from sediment samples from a hot spring at Suryakund, Jharkhand, India. Colonies were pale yellow, rough surface with uneven edges on TSA after 72 h incubation. Heterotrophic growth was observed at 40-60°C and pH 5.5-11.5; optimum growth occurred at 55°C and pH 7.5. 16S rRNA gene sequence analysis revealed the strains belong to genus Anoxybacillus. DNA-DNA homology values among strains were above 70% and showed distinct ERIC and REP PCR profile. On the basis of morphology and biochemical characteristics, strain JS1T was studied further. Strain JS1T showed 99.30% sequence similarity with A. flavithermus subsp. yunnanensis, 99.23% with A. mongoliensis, 99.16% with A. eryuanensis, 98.74% with A. flavithermus subsp. flavithermus, 98.54% with A. tengchongensis, 98.51% with A. pushchinoensis, 97.91% with A. thermarum, 97.82% with A. kaynarcensis, 97.77% with A. ayderensis and A. kamchatkensis, 97.63% with A. salavatliensis, 97.55% with A. kestanbolensis, 97.48% with A. contaminans, 97.27% with A. gonensis and 97.17% with A. voinovskiensis. In 16S rRNA secondary structure based phylogenetic comparison, strain JS1T was clustered with Anoxybacillus eryuanensis, A. mongoliensis, and A. flavithermus subsp. yunnanensis and showed 15 species specific base substitutions with maximum variability in helix 6. Moreover, DNA-DNA relatedness between JS1T and the closely related type strains were well below 70%. The DNA G+C content was 42.1 mol%. The major fatty acids were C15:0 iso, C16:0 iso and C17:0iso. The polar lipids were a phosphatidylgylycerol, a diphosphatidylglycerol, a phosphatidylethnolamine, a phosphatidylcholine, a phosphatidyl monomethylethanolamine and four unknown lipids. Based on polyphasic approach, strain JS1T represent a novel species of the genus Anoxybacillus for which Anoxybacillus suryakundensis sp. nov. is proposed. The type strain is JS1T (= DSM 27374T = LMG 27616T =JCM19211T).
