TL;DR: Members of the family Paenibacillaceae are frequently isolated from various soil habitats, compost, and various plant materials but also from freshwater, blood, and feces.
Abstract: The family Paenibacillaceae has been created on the basis of the analysis of 16S rRNA gene sequences. It embraces the speciesrich type genera Paenibacillus, Ammoniphilus, Aneurinibacillus, Brevibacillus, Cohnella, Oxalophagus, and Thermobacillus and the recently described genera Fontibacillus and Saccharibacillus. Oval to ellipsoid spores are formed, most species are Gram staining positive, and some stain Gram negative. Other characteristics of taxonomic values are varying such as motility, relationship to oxygen, and catalase formation. The major menaquinone is either MK-7 or MK-6; anteiso-C15:0, iso-C15:0, iso-C16:0, and C16:0 are the major fatty acids; and the mol% G+C ranges between 36 and 59. Members of the family are frequently isolated from various soil habitats, compost, and various plant materials but also from freshwater, blood, and feces. The biology of the genus Cohnella is described here in greater detail.

TL;DR: The almost complete 16S rDNA sequence of three strains of the two species of Ammoniphilus shows that the genus falls into the radiation of the Clostridium-Bacillus subphylum of Gram-positive bacteria.
Abstract: The genus Ammoniphilus is proposed for aerobic endospore-forming Gram-variable rod-shaped bacteria, which are ammonium-dependent, obligately oxalotrophic and haloalkalitolerant, oxidase- and catalase-positive, mesophilic and motile by peritrichous flagella. Cell wall contained two electron-dense layers. The external layer consists of a chain of electron-dense granules morphologically resembling the cellulosomes of Clostridium thermocellum. Two species are described, Ammoniphilus oxalaticus gen. nov., sp. nov. and Ammoniphilus oxalivorans gen. nov., sp. nov. The type strains of these species are strains RAOx-1 (= DSM 11538) and RAOx-FS (= DSM 11537), respectively. Ammoniphilus strains were isolated from the rhizosphere of sorrel (Rumex acetosa) and from decaying wood. The strains require a high concentration of ammonium ions and use oxalate as the sole organic source of carbon and energy for growth; no growth factors were required. Growth occurred at pH 6·8--9·5. The optimum temperature and pH for growth were 28--30 °C and 8·0--8·5. All strains grew in a saturated solution of ammonium oxalate, and tolerated 3% NaCl. Whole-cell hydrolysates contain meso-diaminopimelic acid and glucose. The menaquinone of the strains was MK 7, and the major cellular fatty acids were 12-methyl tetradecanoic, cis-hexadec-9-enoic and hexadecanoic acids. The G+C content of the DNA was 45--46 mol% for A. oxalaticus and 42 mol% for A. oxalivorans. The almost complete 16S rDNA sequence of three strains of the two species of Ammoniphilus shows that the genus falls into the radiation of the Clostridium-Bacillus subphylum of Gram-positive bacteria. The closest phylogenetic neighbour of Ammoniphilus is Oxalophagus oxalicus. The DNA-DNA hybridization value between strains RAOx-1 and RAOx-FS was 39·7%.

TL;DR: Ammoniphilus oxalaticus as discussed by the authors is a Gram-variable rod-shaped bacteria which is ammonium-dependent, obligately oxa lotrop h ic and haloa I ka I i to lerant, oxidase- and catal ase-pos i t ive, mesop h i I ic and motile by peritrichous flagella.

The strains require a high concentration of ammonium ions and use oxalate as the sole organic source of carbon and energy for growth; no growth factors were required. Growth occurred at pH 6-8-9-5. The optimum temperature and pH for growth were 28-30 "C and 80-8.5. All strains grew in a saturated solution of ammonium oxalate, and tolerated 3 O/O NaCI. Whole-cell hydrolysates contain meso-diaminopimelic acid and glucose. The menaquinone of the strains was MK 7, and the major cellular fatty acids were 12-methyl tetradecanoic, cis-hexadec-9-enoic and hexadecanoic acids. The G+C content of the DNA was 4546 mol O/O for A. oxalaticus and 42 mol O/O for A. oxalivorans. The almost complete 165 rDNA sequence of three strains of the two species of Ammoniphilus shows that the genus falls into the radiation of the Clostridium-Bacillus subphylum of Grampositive bacteria. The closest phylogenetic neighbour of Ammoniphilus is Oxalophagus oxalicus. The DNA-DNA hybridization value between strains RAOx-1 and RAOx-FS was 3997%.
