Bacillus alkalisediminis sp. nov., an alkaliphilic and moderately halophilic bacterium isolated from sediment of extremely shallow soda ponds Borsodi, Andrea K. and Pollák, Beatrix and Kéki, Zsuzsa and Rusznyák, Anna and Kovács, Attila L. and Spröer, Cathrin and Schumann, Peter and Márialigeti, Károly and Tóth, Erika M.,, 61, 1880-1886 (2011), doi = https://doi.org/10.1099/ijs.0.019489-0, publicationName = Microbiology Society, issn = 1466-5026, abstract= Alkaliphilic strains characterized by optimal growth at pH 9.0 and 5 % (w/v) NaCl designated K1-25T and H3-93 were isolated from extremely shallow soda ponds located in Hungary. Cells of both strains were Gram-stain-positive, non-motile, straight rods and formed central, ellipsoidal endospores with swollen sporangia. The isolates were aerobic, catalase-positive, oxidase-negative and contained a peptidoglycan of type A1γ based on meso-diaminopimelic acid. In both strains, menaquinone-7 (MK-7) was the predominant isoprenoid quinone and the major cellular fatty acids were anteiso-C15 : 0 and iso-C15 : 0. The DNA G+C contents of strains K1-25T and H3-93 were 39.0 and 36.3 mol%, respectively. 16S rRNA gene sequence-based phylogenetic analysis revealed 99.2 % similarity between strains K1-25T and H3-93 and the novel isolates had the highest similarities to Bacillus akibai 1139T (97.8 and 98.3 %, respectively), Bacillus wakoensis N-1T (97.0 and 97.4 %), Bacillus okhensis Kh10-101T (97.1 and 97.4 %) and Bacillus krulwichiae AM31DT (96.9 and 97.1 %). DNA–DNA hybridization between our strains and the type strains of closely related Bacillus species was lower than 70 %. Although DNA–DNA hybridization between strains K1-25T and H3-93 was 27 %, the phenotypic and chemotaxonomic data did not support the differentiation of these two strains into separate species. Therefore, they represent genomovars of a novel species, for which the name Bacillus alkalisediminis sp. nov. is proposed. The type strain is K1-25T ( = DSM 21670T  = NCAIM B02301T)., language=, type=
