Sphingopyxis lindanitolerans sp. nov. strain WS5A3pT enriched from a pesticide disposal site
An aerobic, Gram-stain-negative, rod-shaped, non-motile, mesophilic soil bacterium, strain WS5A3pT, was isolated from a pesticide burial site in north-west Poland. The strain grew at 12–37 °C, at pH 8–9 and with 0–2 % (w/v) NaCl. The main fatty acids detected in WS5A3pT were summed feature 3, summed feature 8 and C16 : 0. The major respiratory quinone was Q-10 and major polar lipids were phosphatidylethanolamine, sphingoglycolipid and phosphatidylglycerol. The G+C content of the genome was 65.1 mol%. Phylogenetic pairwise distance analysis of the 16S rRNA gene placed this strain within the genus Sphingopyxis , with the highest similarity to Sphingopyxis witflariensis W-50T (98.8 %), Sphingopyxis bauzanensis BZ30T and Sphingopyxis ginsengisoli Gsoil 250T (98.3 %) and Sphingopyxis granuli NBRC 100800T (98.09 %). Genomic similarity analyses using ANIb and dDDH algorithms indicated levels of similarity of 81.44, 80.84 and 81.16 % between WS5A3pT and S. witflariensis , S. bauzanensis and S. granuli , respectively for average nucleotide identity and 25.90, 25.00 and 26.10 % for digital DNA–DNA hybridization. Based on the phylogenetic and phenotypic data, strain WS5A3pT should be considered as a representative of a novel Sphingopyxis species. The name Sphingopyxis lindanitolerans sp. nov. is proposed with the type strain WS5A3pT (=DSM 106274T=PCM 2932T).

Mesosutterella multiformis gen. nov., sp. nov., a member of the family Sutterellaceae and Sutterella megalosphaeroides sp. nov., isolated from human faeces
More LessTwo novel, obligately anaerobic, Gram-stain-negative, rod or coccoid-shaped bacteria, designated strains 4NBBH2T and 6FBBBH3T, were isolated from faecal samples of a healthy Japanese woman and man. The 16S rRNA gene sequence analysis showed that these strains represent a distinct lineage within the family Sutterellaceae . Strain 4NBBH2T formed a monophyletic branch between the genera Parasutterella and Sutterella , with sequence similarity to Sutterella stercoricanis CCUG 47620T (92.6 %), followed by Sutterella wadsworthensis WAL 7877 (92.4 %), Sutterella parvirubra YIT 11816T (92.1 %) and Parasutterella secunda YIT 12071T (91.8 %). Strain 6FBBBH3T was affiliated to the genus Sutterella , with highest similarity to S. stercoricanis CCUG 47620T (97.1 %), followed by S. parvirubra YIT 11816T (96.6 %) and S. wadsworthensis WAL 7877 (95.2 %). Strains 4NBBH2T and 6FBBBH3T were asaccharolytic. Analysis of fatty acids revealed that strain 4NBBH2T could be differentiated from Sutterella species (including strain 6FBBBH3T) by the presence of a low concentration of C16 : 1ω7c. The major respiratory quinones of strain 4NBBH2T were menaquinone (MK)-6 and methylmenaquinone (MMK)-6, whereas those of strain 6FBBBH3T were MK-5 and MMK-5. The G+C content of the genomic DNA of strains 4NBBH2T and 6FBBBH3T were 56.9 and 62.8 mol%, respectively. On the basis of the collected data, strain 4NBBH2T represents a novel species in a novel genus of the family Sutterellaceae , for which the name Mesosutterella multiformis gen. nov., sp. nov. is proposed. The type strain is 4NBBH2T (=JCM 32464T=DSM 106860T). We also propose a novel Sutterella species, Sutterella megalosphaeroides sp. nov., for strain 6FBBBH3T (=JCM 32470T=DSM 106861T).

Proposal to modify Rules 27 and 30(3)(b) of the International Code of Nomenclature of Prokaryotes
More LessWe propose to modify Rules 27 and 30(3)(b) of the International Code of Nomenclature of Prokaryotes so that the formal description of new taxa (the ‘protologue’) will include a statement about the nomenclatural type, so that this information will be linked to the name of the taxon, the derivation (etymology) of the name, and the properties of the taxon.
