Actinobaculum Schaalii

A recent study on members of the genus Actinobaculum revealed that cultures of the species Actinobaculum massiliense CCUG 47753T ( = DSM 19118T) currently being distributed do not conform to the properties of the type strain of A. massiliense CIP 107404T given by Greub & Raoult [Greub, G. & Raoult, D. (2002). J Clin Microbiol 40, 3938–3941]. The original strain, CIP 107404T is no longer available from the Biological Resource Center of Institut Pasteur, Paris. Based on data currently available, the organism currently deposited as CCUG 47753T and DSM 19118T is a member of the species Actinobaculum schaalii . Clearly, the organism deposited as CCUG 47753T and DSM 19118T as the type strain of the species Actinobaculum massiliense does not have the properties given by Greub & Raoult. Based on the absence of an authentic type strain, the Judicial Commission is requested to examine the status of the name Actinobaculum massiliense Greub and Raoult 2006 and to issue an Opinion.

Actinobaculum Schaalii

The remarkable host specificity of the species of the genus Actinobaculum led us to recharacterize these species by a polyphasic approach. A comparative chemotaxonomic study including analysis of whole-cell sugars, amino acid composition of the peptidoglycan, fatty acid methyl esters, respiratory quinones and polar lipids revealed significant differences that, in combination with molecular data, support a dissection of the genus Actinobaculum . The proposals of this study include the reclassification of Actinobaculum schaalii and Actinobaculum urinale as Actinotignum schaalii gen. nov., comb. nov. (type strain DSM 15541T = CCUG 27420T) and Actinotignum urinale comb. nov. (type strain DSM 15805T = CCUG 46093T), respectively. Emended descriptions of the genus Actinobaculum and Actinomyces suis are also provided. The results of 16S rRNA gene sequence analysis and DNA–DNA hybridization also indicated that the type strain of Actinobaculum massiliense deposited as CCUG 47753T ( = DSM 19118T) should in fact be considered a member of the species Actinobaculum schaalii . In addition, comparative 16S rRNA gene sequencing and DNA–DNA relatedness studies of four strains recovered from clinical materials demonstrated that three of the isolates belonged to Actinotignum schaalii; the remaining strain represents a novel species, for which the name Actinotignum sanguinis sp. nov. is proposed. The type strain is IMMIB L-2199T ( = DSM 26039T = CCUG 64068T).

Original Type

The species Rhizobium lupini was isolated from Lupinus nodules and included in the Approved Lists of Bacterial Names in 1980. Nevertheless, on the basis of the analysis of the type strain of this species available in DSMZ, DSM 30140T, whose 16S rRNA gene was identical to that of the type strain of Bradyrhizobium japonicum , R. lupini was considered a later synonym of this species. In this study we confirmed that the strain DSM 30140T belongs to the species B. japonicum , but also that it cannot be the original strain of R. lupini because this species effectively nodulated Lupinus whereas strain DSM 30140T was able to nodulate soybean but not Lupinus. Since the original type strain of R. lupini was deposited into the USDA collection by L. W. Erdman under the accession number USDA 3051T we analysed the taxonomic status of this strain showing that although it belongs to the genus Bradyrhizobium instead of genus Rhizobium , it is phylogenetically distant from B. japonicum and closely related to Bradyrhizobium canariense . The type strains R. lupini USDA 3051T and B. canariense BTA-1T share 16S rRNA, recA and glnII gene sequences with similarities of 99.8 %, 96.5 % and 97.1 %, respectively. They presented a DNA–DNA hybridization value of 36 % and also differed in phenotypic characteristics and slightly in the proportions of some fatty acids. Therefore we propose the reclassification of the species Rhizobium lupini as Bradyrhizobium lupini comb. nov. The type strain is USDA 3051T ( = CECT 8630T = LMG 28514T).

Strain Usda

The species Mesorhizobim loti was isolated from nodules of Lotus corniculatus and its type strain deposited in several collections. Some of these type strains, such as those deposited in the USDA and ATCC collections before 1990, are not coincident with the original strain, NZP 2213T, deposited in the NZP culture collection. The analysis of the 16S rRNA gene showed that strains USDA 3471T and ATCC 33669T formed independent branches from that occupied by Mesorhizobium loti NZP 2213T and related to those occupied by Mesorhizobium opportunistum WSM2075T and Mesorhizobium huakuii IFO 15243T, respectively, with 99.9 % similarity in both cases. However, the analysis of concatenated recA, atpD and glnII genes with similarities lower than 96, 98 and 94 %, respectively, between strains USDA 3471T and M. opportunistum WSM2075T and between strains ATCC 33669T and M. huakuii IFO 15243T, indicated that the strains USDA 3471T and ATCC 33669T represent different species of the genus Mesorhizobium . These results were confirmed by DNA–DNA hybridization experiments and phenotypic characterization. Therefore, the two strains were reclassified as representatives of the two species Mesorhizobium erdmanii sp. nov. (type strain USDA 3471T = CECT 8631T = LMG 17826t2T) and Mesorhizobium jarvisii sp. nov. (type strain ATCC 33669T = CECT 8632T = LMG 28313T).

Rejected Names

On the basis of 16S rRNA gene sequence analysis and several key phenotypic features, it was ascertained that the culture cited as the type strain of the species Hyphomonas rosenbergii , ATCC 43869T, does not conform to the description of the species, [Weiner, R. M., Melick, M., O’Neill, K. & Quintero, E. (2000). Int J Syst Evol Microbiol 50, 459–469]. The type strain does not exist in any other established culture collection or with the authors who described this species. Therefore, it cannot be included in any scientific study. It is proposed that the Judicial Commission place the name Hyphomonas rosenbergii on the list of rejected names if a suitable replacement type strain is not found or a neotype is not proposed within two years following the publication of this Request for an Opinion.

During a recent study on members of the genus Lactobacillus we realized that cultures of Lactobacillus fornicalis TV 1018T (=DSM 13171T=ATCC 700934T) are no longer available from the online catalogue of the German Collection of Microorganisms and Cell Cultures GmbH, being displayed as Lactobacillus plantarum at the American Type Culture Collection. Based on data currently available, the organism deposited as ATCC 700934T is a member of the species Lactobacillus plantarum subs. plantarum. Therefore, the type strain of Lactobacillus fornicalis cannot be included in any further scientific comparative study. This matter is referred to the Judicial Commission, asking for an opinion on the status of the species.

The Status

The Judicial Commission affirms that the combination Lactobacillus rogosae Holdeman and Moore 1974 represented by the type strain ATCC 27753 listed on the Approved Lists of Bacterial Names does not appear to be currently represented by an extant type strain. Further work is needed to determine whether a derivative of the original type can be found or whether a neotype can be designated.

A Gram-stain-negative, non-motile, aerobic and pleomorphic bacterium, designated BS-W13T, was isolated from a tidal flat on the South Sea, South Korea, and its taxonomic position was investigated using a polyphasic approach. Strain BS-W13T grew optimally at 25 °C, at pH 7.0–8.0 and in the presence of 1.0–2.0 % (w/v) NaCl. Neighbour-joining and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences showed that strain BS-W13T clustered with the type strain of Seohaeicola saemankumensis , showing the highest sequence similarity (95.96 %) to this strain. Strain BS-W13T exhibited 16S rRNA gene sequence similarity values of 95.95, 95.91, 95.72 and 95.68 % to the type strains of Sulfitobacter donghicola , Sulfitobacter porphyrae , Sulfitobacter mediterraneus and Roseobacter litoralis , respectively. Strain BS-W13T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid. The polar lipid profile of strain BS-W13T, containing phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, one unidentified aminolipid and one unidentified lipid as major components, was distinguishable from those of some phylogenetically related taxa. The DNA G+C content of strain BS-W13T was 58.1 mol%. The phylogenetic data and differential chemotaxonomic and other phenotypic properties revealed that strain BS-W13T constitutes a novel genus and species within family Rhodobacteraceae of the class Alphaproteobacteria , for which the name Pseudoseohaeicola caenipelagi gen. nov., sp. nov. is proposed. The type strain is BS-W13T ( = KCTC 42349T = CECT 8724T).

Previous Proposal

The taxonomic status of saltwater Bdellovibrio -like prokaryotic predators has been revised to assign species to Halobacteriovorax gen. nov. A reclassification of Bacteriovorax marinus as Halobacteriovorax marinus comb. nov. (type strain ATCC BAA-682T = DSM 15412T) and Bacteriovorax litoralis as Halobacteriovorax litoralis comb. nov. (type strain ATCC BAA-684T = DSM 15409T) is proposed. This revision is necessary because a previous proposal to retain saltwater isolates as species of Bacteriovorax and reclassify Bacteriovorax stolpii as Bacteriolyticum stolpii was not approved. The type species of a genus cannot be reassigned to another genus. Bacteriovorax stolpii is thus retained as the type species of Bacteriovorax and Halobacteriovorax marinus is the type species of Halobacteriovorax and of Halobacteriovoraceae fam. nov.

Strain HNM0947T, representing a novel actinobacterium, was isolated from the coral Galaxea astreata collected from the coast of Wenchang, Hainan, China. The strain was found to have morphological and chemotaxonomic characteristics consistent with the genus Nocardiopsis . The organism formed abundant fragmented substrate mycelia and aerial mycelia which differentiated into non-motile, rod-shaped spores. Whole-cell hydrolysates contained meso-diaminopimelic acid and no diagnostic sugars. The major menaquinones were MK-10(H8), MK-10(H6) and MK-10(H4). The major phospholipids were phosphatidylcholine, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannosides. The major fatty acids were iso-C16:0, anteiso-C17:0, C18:0, C18:0 10-methyl (TBSA) and anteiso-C15:0. The G+C content was 71.3 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain HNM0947T belonged to the genus Nocardiopsis and shared highest sequence similarity to Nocardiopsis salina YIM 90010T (98.8%), Nocardiopsis xinjiangensis YIM 90004T(98.5%) and Nocardiopsis kunsanensis DSM 44524T (98.3%). The strain HNM0947T was distinguished from its closest type strain by low average nucleotide identity (90.8%) and dDDH values (60.4%) respectively. Based on genotypic, chemotaxonomic and phenotypic characteristics, it was concluded that strain HNM0947T represents a novel species of the genus Nocardiopsis whose name was proposed as Nocardiopsis coralli sp. nov. The type strain was HNM0947T (=CCTCC AA 2020015 T=KCTC 49525 T).

The strain Adlercreutzia caecicola DSM 22242T (=CCUG 57646T=NR06T) was taxonomically described in 2013 and named as Parvibacter caecicola Clavel et al. 2013. In 2018, the name of the strain DSM 22242T was changed to Adlercreutzia caecicola (Clavel et al. 2013) Nouioui et al. 2018 due to taxonomic investigations of the closely related genera Adlercreutzia, Asaccharobacter and Enterorhabdus within the phylum Actinobacteria . However, the first whole draft genome of strain DSM 22242T was published by our group in 2019. Therefore, the genome was not available within the study of Nouioui et al. (2018). The results of the polyphasic approach within this study, including phenotypic and biochemical analyses and genome-based taxonomic investigations [genome-wide average nucleotide identity (gANI), alignment fraction (AF), average amino acid identity (AAI), percentage of orthologous conserved proteins (POCP) and genome blast distance phylogeny (GBDP) tree], indicated that the proposed change of the name Parvibacter caecicola to Adlercreutzia caecicola was not correct. Therefore, it is proposed that the correct name of Adlercreutzia caecicola (Clavel et al. 2013) Nouioui et al. 2018 strain DSM 22242T is Parvibacter caecicola Clavel et al. 2013.
