Ten species of the order Myxococcales with validly published names are devoid of living type strains. Four species of the genus Chondromyces are represented by dead herbarium samples as the type material. For a species of the genus Melittangium and two species of the genus Polyangium , no physical type material was assigned at the time of validation of the names or later on. In accordance with rule 18f of the International Code of Nomenclature of Bacteria the following type strains are designated for these species: strain Cm a14T ( = DSM 14605T = JCM 12615T) as the type strain of Chondromyces apiculatus , strain Cm c5T ( = DSM 14714T = JCM 12616T) as the type strain of Chondromyces crocatus , strain Sy t2T ( = DSM 14631T = JCM 12617T) as the type strain of Chondromyces lanuginosus , strain Cm p51T ( = DSM 14607T = JCM 12618T) as the type strain of Chondromyces pediculatus , strain Me b8T ( = DSM 14713T = JCM 12633T) as the type strain of Melittangium boletus , strain Pl s12T ( = DSM 14670T = JCM 12637T) as the type strain of Polyangium sorediatum and strain Pl sm5T ( = DSM 14734T = JCM 12638T) as the type strain of Polyangium spumosum . Furthermore, the type strains given for three species of the genera Cystobacter and Polyangium had been kept at one university institute and have been lost according to our investigations. In accordance with Rule 18c of the Bacteriological Code, we propose the following neotype strains: strain Cb fe18 ( = DSM 14716  = JCM 12624) as the neotype strain of Cystobacter ferrugineus , strain Cb m2 ( = DSM 14751 = JCM 12627) as the neotype strain of Cystobacter minus and strain Pl fu5 ( = DSM 14668 = JCM 12636) as the neotype strain of Polyangium fumosum . The proposals of the strains are based on the descriptions and strain proposals given in the respective chapters of Bergey’s Manual of Systematic Bacteriology (2005).

Laboratory Collection

The Pectobacteriaceae family of important plant pathogens includes the genus Dickeya . There are currently 12 described species of Dickeya , although some are poorly characterized at the genomic level. Only two genomes of Dickeya paradisiaca , the type strain CFBP 4178T and strain Ech703, have previously been sequenced. Members of this species are mostly of tropical or subtropical origin. During an investigation of strains present in our laboratory collection we sequenced the atypical strain A3967, registered as CFBP 722, isolated from Solanum lycopersicum (tomato) in the South of France in 1965. The genome of strain A3967 shares digital DNA–DNA hybridization and average nucleotide identity (ANI) values of 68 and 96 %, respectively, with the D. paradisiaca type strain CFBP 4178T. However, ANI analysis showed that D. paradisiaca strains are significantly dissimilar to the other Dickeya species, such that less than one third of their genomes align to any other Dickeya genome. On phenotypic, phylogenetic and genomic grounds, we propose a reassignment of D. paradisiaca to the genus level, for which we propose the name Musicola gen. nov., with Musicola paradisiaca as the type species and CFBP 4178T (NCPPB 2511T) as the type strain. Phenotypic analysis showed differences between strain A3967T and CFBP 4178T, such as for the assimilation of melibiose, raffinose and myo-inositol. These results support the description of two novel species, namely Musicola paradisiaca comb. nov. and Musicola keenii sp. nov., with CFBP 4178T (NCPPB 2511T=LMG 2542T) and A3967T (CFBP 8732T=LMG 31880T) as the type strains, respectively.

A Gram-stain-negative, aerobic, non-spore-forming, motile by single polar flagellum and ovoid or rod-shaped bacterial strain, designated JBTF-M23T, was isolated from tidal flat sediment collected from the Yellow Sea, Republic of Korea. Neighbour-joining phylogenetic tree of 16S rRNA gene sequences showed that strain JBTF-M23T fell within the clade comprising the type strains of Pseudoalteromonas species, clustering with the type strains of P. byunsanensis and P. amylolytica . Strain JBTF-M23T exhibited the highest 16S rRNA gene sequence similarity value (98.6 %) to the type strain of P. rubra and sequence similarities of 98.3 and 97.7 % to the type strains of P. byunsanensis and P. amylolytica, respectively. The DNA G+C content of strain JBTF-M23T from genomic sequence data was 41.98 %. The ANI and dDDH values between strain JBTF-M23T and the type strains of P. rubra , P. byunsanensis and P. amylolytica were 71.3–76.6 and 19.4–19.9 %, respectively. Strain JBTF-M23T contained Q-8 as the predominant ubiquinone and C16 : 1  ω7c and/or C16 : 1  ω6c, C16 : 0 and C18 : 1  ω7c as the major fatty acids. The major polar lipids of strain JBTF-M23T were phosphatidylethanolamine and one unidentified aminolipid. Distinguished phenotypic properties, along with the phylogenetic and genetic distinctiveness, revealed that strain JBTF-M23T is separated from recognized Pseudoalteromonas species. On the basis of the data presented, strain JBTF-M23Tis considered to represent a novel species of the genus Pseudoalteromonas , for which the name Pseudoalteromonas caenipelagi sp. nov. is proposed. The type strain is JBTF-M23T(=KACC 19900T=NBRC 113647T).

A Gram-stain-negative, non-motile, aerobic, curved-to-spiral-rod-shaped bacterium, designated AH-MY2T, was isolated from a tidal flat on Aphae island in the sea to the south-west of South Korea, and its taxonomic position was investigated using a polyphasic taxonomic approach. Strain AH-MY2T grew optimally at 30 °C, at pH 7.0–8.0 and in the presence of 2.0 % (w/v) NaCl. Neighbour-joining, maximum-likelihood and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences showed that strain AH-MY2T clustered with the type strain of Terasakiella pusilla and that this cluster joined the clade comprising the type strains of species of the genus Thalassospira . Strain AH-MY2T exhibited 16S rRNA gene sequence similarity values of 90.6 % to the type strain of Terasakiella pusilla and of less than 91.0 % to the type strains of other species with validly published names. Strain AH-MY2T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid. The major polar lipids detected in strain AH-MY2T were phosphatidylglycerol, phosphatidylethanolamine, two unidentified aminolipids and one unidentified glycolipid. The DNA G+C content of strain AH-MY2T was 56.0 mol%. The phylogenetic data and differential chemotaxonomic and other phenotypic properties revealed that strain AH-MY2T represented a novel genus and species within the family Rhodospirillaceae of the class Alphaproteobacteria , for which the name Aestuariispira insulae gen. nov., sp. nov. is proposed. The type strain of Aestuariispira insulae is AH-MY2T ( = KCTC 32577T = CECT 8488T).

The International Committee on Systematics of Prokaryotes has formally made final decisions, taking into account the conclusions of the Judicial Commission, on three pending Requests for an Opinion, thereby allowing the corresponding Opinions to be issued. According to Opinion 100, the request for the recognition of strain A1-86 (=DSM 17629=NCIMB 14373) as the neotype strain of Eubacterium rectale (Hauduroy et al. 1937) Prévot 1938 (Approved Lists 1980) is denied, ruling that a neotype does not need to be designated for E. rectale because strain VPI 0990 (=ATCC 33656=CIP 105953) is considered to be a duplicate isolate of the same strain as VPI 0989 (=ATCC 25578) and may serve as its nomenclatural type. Opinion 101 approves the request that strain ATCC 25946 (=DSM 14877) serves as the type strain of Melittangium lichenicola instead of strain ATCC 25944, formally correcting the Approved Lists of Bacterial Names. Opinion 102 concludes that strain Cc m8 (=DSM 14697=CIP 109128=JCM 12621) is an established neotype strain for the species Myxococcus macrosporus , replacing the designated type strain Windsor M271, and that strain Mx s8 (=DSM 14675=JCM 12634) is an established neotype strain for the species Myxococcus stipitatus , replacing the designated type strain Windsor M78, with some additional considerations about the nature of the type material replaced and about the name Corallococcus ( Myxococcus ) macrosporus.

A recent review of the nomenclatural history of Rhodococcus equi and its heterotypic synonyms reveals a situation in which the strict application of the Rules of the International Code of Nomenclature of Prokaryotes have resulted in the renaming of this known zoonotic pathogen, which may be reasonably viewed as a perilous name. This situation can be remedied only by the Judicial Commission rendering an opinion to conserve the name Rhodococcus equi and to reject its earlier heterotypic synonym, Corynebacterium hoagii .

An actinobacterial strain, designated ViU22T, was isolated from a natural uranium-rich soil and was studied using a polyphasic approach. Cells formed orange-pigmented colonies, were rod-shaped, Gram-positive (non-staining method), non-motile and non-spore-forming. This organism grew in 0–4.5 % (w/v) NaCl and at 15–37 °C, with optimal growth occurring in 0.5 % (w/v) NaCl and at 30 °C. Comparative 16S rRNA gene sequence analysis revealed that the strain ViU22T belonged to the genus Microbacterium . It exhibited highest 16S rRNA gene sequence similarity with the type strains of Microbacterium testaceum (98.14 %) and Microbacterium binotii (98.02 %). The DNA–DNA relatedness of strains ViU22T with the most closely related type strains Microbacterium testaceum and Microbacterium binotii DSM 19164T was 20.10 % (±0.70) and 28.05 % (±0.35), respectively. Strain ViU22T possessed a type B2β peptidoglycan with partial substitution of glutamic acid by 3-hydroxy glutamic acid. The major menaquinones were MK-11 and MK-12. Major polar lipids detected in the strain ViU22T were diphosphatidylglycerol, phosphatidylglycerol, an unknown phospholipid and unknown glycolipids. The predominant fatty acids were anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0, a pattern reported for other Microbacterium species. The major cell-wall sugars were galactose, xylose and mannose and the DNA G+C content was 71 mol%. Together, the DNA–DNA hybridization results and the differentiating phenotypic characteristics, showed that strain ViU22T should be classified as the type strain of a novel species within the genus Microbacterium , for which the name Microbacterium lemovicicum sp. nov. is proposed. The type strain is ViU22T ( = ATCC BAA-2396T = CCUG 62198T = DSM 25044T).

A Gram-negative, non-motile and coccoid, ovoid or rod-shaped bacterial strain, designated MA1-1T, was isolated from a sea squirt (Halocynthia roretzi) collected from the South Sea, Korea. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain MA1-1T is phylogenetically closely related to Litoreibacter species and to Thalassobacter arenae . It exhibited 16S rRNA gene sequence similarities of 97.3, 97.1 and 97.3 % to the type strains of Litoreibacter albidus , Litoreibacter janthinus and T. arenae , respectively. Strain MA1-1T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the predominant fatty acid. The polar lipid profile of strain MA1-1T was similar to those of the type strains of L. albidus and L. janthinus . T. arenae was found to be phylogenetically and chemotaxonomically more closely related to Litoreibacter species and strain MA1-1T than to Thalassobacter stenotrophicus , the type species of the genus Thalassobacter . The DNA G+C content of strain MA1-1T was 57.9 mol%, and DNA–DNA relatedness to the type strains of the two Litoreibacter species and T. arenae was 9–14 %. Differential phenotypic properties, together with the observed phylogenetic and genetic distinctiveness, distinguished strain MA1-1T from the two Litoreibacter species and T. arenae . On the basis of the data presented, strain MA1-1T is considered to represent a novel species of the genus Litoreibacter , for which the name Litoreibacter meonggei sp. nov. is proposed. The type strain is MA1-1T ( = KCTC 23699T  = CCUG 61486T). In this study, it is also proposed that Thalassobacter arenae is reclassified as a member of the genus Litoreibacter , Litoreibacter arenae comb. nov. (type strain GA2-M15T  = DSM 19593T  = KACC 12675T). An emended description of the genus Litoreibacter is also presented.

A Gram-stain-negative, coccoid- or oval-shaped, gliding bacterial strain, designated HDW-31T, belonging to the class Alphaproteobacteria , was isolated from seawater of the Yellow Sea, Korea, and was subjected to a taxonomic study using a polyphasic approach. Strain HDW-31T grew optimally at pH 7.0–8.0, at 30 °C and in the presence of 2–3 % (w/v) NaCl. Neighbour-joining, maximum-likelihood and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences showed that strain HDW-31T fell within the clade comprising the genus Altererythrobacter , clustering with the type strains of Altererythrobacter luteolus and Altererythrobacter gangjinensis , with which strain HDW-31T exhibited 97.0 and 96.0 % sequence similarity values, respectively. Sequence similarities to the type strains of the other recognized species of the genus Altererythrobacter were 93.5–96.0 %. The DNA G+C content was 57.9 mol% and mean DNA–DNA relatedness between strain HDW-31T and the type strain of A. luteolus was 5.3 %. Strain HDW-31T contained Q-10 as the predominant ubiquinone and summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c), summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c) and C16 : 0 as the major fatty acids. The major polar lipids were phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, a sphingoglycolipid, two unidentified glycolipids and an unidentified lipid. Differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, demonstrated that strain HDW-31T is distinguishable from recognized species of the genus Altererythrobacter . On the basis of the data presented, strain HDW-31T is considered to represent a novel species of the genus Altererythrobacter , for which the name Altererythrobacter aestiaquae sp. nov. is proposed. The type strain is HDW-31T ( = KCTC 42006T = CECT 8527T).

A Gram-stain-negative, non-motile, non-spore-forming, aerobic, rod-shaped bacterial strain, designated DPG-28T, was isolated from seawater on the southern coast of Korea. Strain DPG-28T grew optimally at 30 °C and in the presence of 2 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain DPG-28T formed a coherent cluster with members of the genera Marivita and Gaetbulicola , with which it exhibited sequence similarity values of 97.8–98.5 %. The DNA G+C content of strain DPG-28T was 65.1 mol%. The predominant ubiquinone of strain DPG-28T was ubiquinone-10 (Q-10), consistent with data for the genera Marivita and Gaetbulicola . The cellular fatty acid profiles of strain DPG-28T and the type strains of Marivita cryptomonadis , Marivita litorea and Gaetbulicola byunsanensis were essentially similar in that the common predominant fatty acid was C18 : 1ω7c. Major polar lipids found in strain DPG-28T and the type strains of M. cryptomonadis , M. litorea and G. byunsanensis were phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine and an unidentified aminolipid. From these data, it is proposed that Gaetbulicola byunsanensis be reclassified as a member of the genus Marivita , for which the name Marivita byunsanensis comb. nov. is proposed, with the type strain SMK-114T ( = CCUG 57612T  = KCTC 22632T), and that strain DPG-28T be classified in the genus Marivita . Differential phenotypic properties and genetic distinctiveness of strain DPG-28T demonstrated that this strain is distinguishable from M. cryptomonadis , M. litorea and G. byunsanensis . On the basis of the data presented, strain DPG-28T is considered to represent a novel species of the genus Marivita , for which the name Marivita hallyeonensis sp. nov. is proposed. The type strain is DPG-28T ( = KCTC 23421T  = CCUG 60522T). An emended description of the genus Marivita is also provided.
