Inhella crocodyli sp. nov., isolated from a crocodile pond
More LessStrain CCP-18T, isolated from a freshwater pond in Taiwan, was characterized by using a polyphasic taxonomy approach. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain CCP-18T belongs to the genus Inhella and has the highest levels of sequence similarity with respect to Inhella inkyongensis IMCC1713T (98.9 %) and Inhella fonticola TNR-25T (98.0 %). Cells were Gram-stain-negative, aerobic, motile, rod-shaped and formed white-coloured colonies. Optimal growth occurred at 25 °C, pH 6 and in the absence of NaCl. The major fatty acids of strain CCP-18T were summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0. The polar lipid profile consisted of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, two unidentified aminophospholipids, an unidentified phospholipid, an unidentified aminolipid and an unidentified lipid. The predominant polyamine was putrescine. The major isoprenoid quinone was Q-8. The draft genome was approximately 3.76 Mb in size with a G+C content of 68.9 mol%. The DNA–DNA hybridization values for strain CCP-18Twith I. inkyongensis IMCC1713T and I.nhella fonticola TNR-25T were less than 40 %. Based on the phylogenetic and phenotypic data, strain CCP-18T should be classified within the genus Inhella as a representative of a novel species, named Inhella crocodyli sp. nov. The type strain is CCP-18T (=BCRC 81120T=LMG 30595T=KCTC 62511T).

Acidimangrovimonas sediminis gen. nov., sp. nov., isolated from mangrove sediment and reclassification of Defluviimonas indica as Acidimangrovimonas indica comb. nov. and Defluviimonas pyrenivorans as Acidimangrovimonas pyrenivorans comb. nov.
More LessA Gram-stain-negative, aerobic, non-motile, short-rod bacterium, strain MS2-2T, was isolated from mangrove sediment sampled at Jiulong River Estuary, Fujian province, PR China. 16S rRNA gene sequence similarity analysis showed that strain MS2-2T was most closely related to Defluviimonas indica 20V17T (97.41 %) and Defluviimonas pyrenivorans PrR001T (96.18 %). Phylogenetic trees based on 16S rRNA genes and genome sequences both revealed that strain MS2-2T formed a distinct cluster with D. indica 20V17T and D. pyrenivorans PrR001T within family Rhodobacteracea, quite separate from other type species in the genus Defluviimonas . The average nucleotide identity value between strain MS2-2T and D. indica 20V17T was 78.35 %. Growth of strain MS2-2T was observed at 16–41 ° C (optimum, 34 ° C), pH 3.6–7.5 (pH 6.0) and 0.5–10.0 % (w/v) NaCl (4.0 %). The major cellular fatty acids were summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c), C16 : 0 and C18 : 0. Ubiquinone 10 was the sole quinone. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The DNA G+C content was 67.9 mol%. The combined genotypic and phenotypic data show that strain MS2-2T represents a novel species of a novel genus in the family Rhodobacteraceae , for which the name Acidimangrovimonassediminis gen. nov., sp. nov. is proposed, with the type strain MS2-2T (=MCCC 1K02682T=NBRC 112978T). We also propose the reclassification of Defluviimonas indica as Acidimangrovimonas indica comb. nov. and Defluviimonas pyrenivorans as Acidimangrovimonas pyrenivorans comb. nov.

A Gram-stain-negative, aerobic, yellow-pigmented, oxidase-positive and rod-shaped bacterium, designated PRB40T, was isolated from the Godavari River in India during the course of ‘Kumbh Mela’, the world’s largest mass gathering event. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain PRB40T formed a lineage within the family Sphingomonadaceae and was distinct from the most closely related genera Sphingorhabdus , Novosphingobium and Sphingomonas with sequence similarity values ≤95.2 %. Growth of strain PRB40T occurred at 10–40 °C (optimum 30 °C), at pH 6.0–9.0 (pH 7.0) and with 0–0.5 % (w/v) NaCl concentration (0 %). The major respiratory quinone was ubiquinone-10 (Q-10). It contained C17 : 1ω6c, C14 : 0 2-OH, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c) as the major cellular fatty acids. The predominant polar lipids were phospholipid, phosphatidylethanolamine and sphingoglycolipid. It took sym-homospermidine as the major polyamine. The DNA G+C content based on its draft genome sequence was 63.7 mol%. The polyphasic taxonomic analyses indicated that strain PRB40T represents a novel species of a novel genus within the family Sphingomonadaceae , for which the name Chakrabartia godavariana gen. nov., sp. nov. is proposed. The type strain of Chakrabartia godavariana is PRB40T (=MCC 3406T=GDMCC 1.1197T=KCTC 52678T=LMG 29985T).

Sphingobium terrigena sp. nov., isolated from gasoline-contaminated soil
More LessA Gram-stain-negative, strictly aerobic bacterial strain, designated EO9T, was isolated from gasoline-contaminated soil in the Republic of Korea. Cells were non-motile short rods showing catalase- and oxidase-positive reactions. Growth was observed at 10–37 °C (optimum, 30 °C), at pH 6.0–9.0 (pH 6.5) and in the presence of 0–0.5 % (w/v) NaCl (0 %). Ubiquinone-10 (Q-10) and spermidine were identified as the predominant respiratory quinone and polyamine, respectively. Summed feature 8 (comprising C18:1ω7c/C18:1ω6c), summed feature 3 (comprising C16:1ω7c/C16:1ω6c), C16:0 and C14:0 2-OH were identified as major cellular fatty acids. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, sphingoglycolipid, phosphatidylglycerol and an unidentified phospholipid. The G+C content of the genomic DNA was 62.8 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain EO9T formed a tight phylogenetic lineage with Sphingobium xenophagum NBRC 107872T and Sphingobium hydrophobicum C1T within the genus Sphingobium . Strain EO9T was most closely related to S. xenophagum NBRC 107872T (97.2 %) and S. hydrophobicum C1T (97.2 %), but DNA–DNA relatedness levels between strain EO9T and the type strains of S. xenophagum and S. hydrophobicum were 37.1 and 36.8 % , respectively. Based on its phenotypic, chemotaxonomic and molecular features, strain EO9T clearly represents a novel species of the genus Sphingobium , for which the name Sphingobium terrigena sp. nov. is proposed. The type strain is EO9T (=KACC 19523T=JCM 32762T).

Pseudomonas nitrititolerans sp. nov., a nitrite-tolerant denitrifying bacterium isolated from a nitrification/denitrification bioreactor
More LessA nitrite-tolerant denitrifying bacterium, strain GL14T, was isolated from the nitrification/denitrification bioreactor in our laboratory. Strain GL14T was Gram-stain-negative, rod-shaped, non-spore-forming, facultatively anaerobic and motile by means of a single polar flagellum. Phylogenetic analyses based on 16S rRNA gene sequences indicated that it was assigned to the genus Pseudomonas with highest 16S rRNA gene sequence similarity (98.77 %) to Pseudomonas xanthomarina DSM 18231T and Pseudomonas songnenensis NEAU-ST5-5T, followed by Pseudomonas stutzeri ATCC 17588T (98.42 %), Pseudomonas kunmingensis HL22-2T (98.29 %) and Pseudomonas zhaodongensis NEAU-ST5-21T (98.22 %). Phylogenetic analysis based on both concatenated sequences of the 16S rRNA gene and two housekeeping genes (gyrB and rpoD) and genome sequences further clarified the intrageneric phylogenetic position of strain GL14T. The DNA G+C content of GL14T was 63.1 mol%. The results of digital DNA–DNA hybridization (highest 24.2 % of DNA–DNA relatedness) based on the Genome-to-Genome Distance Calculator and average nucleotide identity analyses (highest 80.23 %) confirmed that the strain was distinctly delineated from known species of the genus Pseudomonas . The major fatty acids were summed feature 8 (C18 : 1 ω7c/C18 : 1 ω6c), C16 : 0, summed feature 3 (C16 : 1 ω7c/C16 : 1 ω6c), C17 : 0cyclo and C12 : 0. The respiratory quinone was ubiquinone Q-9. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. Based on the phylogenetic, genomic, phenotypic and chemotaxonomic analyses, it was concluded that strain GL14T represents a novel species of the genus Pseudomonas , for which the name Pseudomonas nitrititolerans sp. nov. is proposed. The type strain is GL14T (=CGMCC 1.13874T=NBRC 113853T).

Alteromonas fortis sp. nov., a non-flagellated bacterium specialized in the degradation of iota-carrageenan, and emended description of the genus Alteromonas
More LessStrain 1T, isolated in the 1970s from the thallus of the carrageenophytic red algae, Eucheuma spinosum, collected in Hawaii, USA, was characterized using a polyphasic method. Cells were Gram-stain-negative, strictly aerobic, non-flagellated, ovoid or rod-shaped and grew optimally at 20–25 °C, at pH 6–9 and with 2–4 % NaCl. Strain 1T used the seaweed polysaccharides ι-carrageenan, laminarin and alginic acid as sole carbon sources. The major fatty acids were C16 : 0, C18 : 1 ω7c and summed feature 3 (C16 : 1 ω7c and/or iso-C15 : 0 2OH) with significant amounts (>6 %) of C16 : 0 N alcohol and 10 methyl C17 : 0. The respiratory quinone was Q-8 and major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and an unknown aminolipid. Phylogenetic analyses showed that the bacterium is affiliated to the genus Alteromonas (family Alteromonadaceae , class Gammaproteobacteria ). Strain 1T exhibited 16S rRNA gene sequence similarity values of 98.8 and 99.2 % to the type strains of Alteromonas mediterranea and Alteromonas australica respectively, and of 95.2–98.6 % to other species of the genus Alteromonas . The DNA G+C content of strain 1T was determined to be 43.9 mol%. Digital DNA–DNA hybridization predictions by the ANI and GGDC methods between strain 1T and other members of the genus Alteromonas showed values below 83 % and 30 %, respectively. The phenotypic, phylogenetic and genomic analyses show that strain 1T is distinct from species of the genus Alteromonas with validly published names and that it represents a novel species of the genus Alteromonas , for which the name Alteromonas fortis sp. nov. is proposed. The type strain is 1T (=ATCC 43554T=RCC 5933T=CIP 111645T=DSM 106819T).

Parvularcula marina sp. nov., isolated from surface water of the South China Sea, and emended description of the genus Parvularcula
A Gram-stain-negative, aerobic, flagellated, rod-shaped bacterial strain, SM1705T, was isolated from a surface seawater sample collected from the South China Sea. The strain grew at 10–40 °C and with 0.5–13.0 % (w/v) NaCl. It hydrolysed Tweens 20, 40 and 60, but did not hydrolyse starch or Tween 80 nor reduce nitrate to nitrite. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain SM1705T was affiliated with the genus Parvularcula , sharing the highest sequence similarity (96.0 %) with type strain of Parvularcula bermudensis and forming a coherent branch together with the latter within the clade of Parvularcula . The major cellular fatty acids were identified as summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c), C16 : 0 and C18 : 0. Polar lipids included three unidentified glycolipids and one unidentified lipid. The major respiratory quinone of strain SM1705T was Q10. The genomic DNA G+C content of strain SM1705T was 59.3 mol%. Based on the polyphasic evidence presented in this paper, strain SM1705T represents a novel Parvularcula species, for which the name Parvularcula marina sp. nov. is proposed. The type strain is SM1705T (=KCTC 62795T=MCCC 1K03505T=CCTCC AB 2018345T).

Croceibacterium gen. nov., with description of Croceibacterium ferulae sp. nov., an endophytic bacterium isolated from Ferula sinkiangensis K. M. Shen and reclassification of Porphyrobacter mercurialis as Croceibacterium mercuriale comb. nov.
A novel endophytic bacterium, designated strain SX2RGS8T, was isolated from the surface-sterilized roots of an endangered medicinal plant (Ferula sinkiangensis K. M. Shen) collected from Xinjiang, north-western PR China. The taxonomic position of the candidate was investigated using a polyphasic approach. Strain SX2RGS8T was found to be aerobic, Gram-stain-negative, oxidase-negative, catalase-positive and axiolitic-shaped. Strain SX2RGS8T grew at 4–45 °C (optimum, 28 °C), pH 4.0–10.0 (pH 7.0) and in the presence of 0–5 % (w/v) NaCl. The polar lipids detected for strain SX2RGS8T were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, phosphatidylinositol, unidentified phosphoglycolipids, an unidentified phospholipid and unidentified lipids. The major respiratory quinone of strain SX2RGS8T was ubiquinone 10 and the major fatty acid was summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c). The DNA G+C content was determined to be 66.5 mol%. Phylogenetic analyses based on 16S rRNA gene sequences indicated that the isolate belonged to the family Erythrobacteraceae and showed 99.2 % ( Porphyrobacter mercurialis ), 95.5 % ( Porphyrobacter donghaensisi) and 95.4 % ( Porphyrobacter colymbi ) similarities to its closest relatives. The isolate contained carotenoids, but no bacteriochlorophyll a. On the basis of phenotypic, genotypic and phylogenetic data, strain SX2RGS8T represents a novel species of a novel genus in the family Erythrobacteraceae , for which the name Croceibacterium ferulae gen. nov., sp. nov. is proposed. The type strain is SX2RGS8T (=CGMCC 1.16402T=KCTC 62090T). In addition, Porphyrobacter mercurialis Coil et al. 2016 is proposed to be transferred to this new genus as Croceibacterium mercuriale comb. nov.

Tabrizicola sediminis sp. nov., one aerobic anoxygenic photoheterotrophic bacteria from sediment of saline lake
More LessTwo strains of Gram-stain-negative, non-motile, aerobic, short-rod bacteria, designated as DRYC-M-16T and WMC-M-20, were isolated from sediment samples of two saline lakes in the Tibet of China. Both of the strains were catalase- and oxidase-positive. Optimal growth of strain DRYC-M-16T occurred at 20–25 °C, pH 7.0–7.5 and with 1.5 % (w/v) NaCl concentration. The analysis of 16S rRNA gene sequences indicated that strains DRYC-M-16T and WMC-M-20 belonged to the genus Tabrizicola , and showed the highest similarities to Tabrizicola aquatica KCTC 23724T (96.9 %) and Tabrizicola fusiformis KCTC 62105T (96.7 %). The DNA G+C contents of strains DRYC-M-16T and WMC-M-20 were 63.0 mol% and 62.9 mol%, respectively. The main polar lipids contained phosphatidylglycerol (PG), diphosphatidylglycerol (DPG), phosphatidylethanolamine (PE), phosphatidylcholine (PC) and several unidentified aminophospholipid (APL), aminolipid (AL), phospholipids (PL) and lipids (L). The predominant respiratory quinone was ubiquinone Q-10. The major cellular fatty acids of the two strains were iso-C18 : 0 and summed feature 8 (comprising C18 : 1 ω7c/C18 : 1 ω6c). Comprehensive analysis of the genotypic, physiological, biochemical and phenotypic characteristics indicated that the two strains should be classified as a novel species of the genus Tabrizicola , proposed as Tabrizicola sediminissp. nov., with the type strain DRYC-M-16T (=CGMCC 1.13881T=KCTC 72105 T).

Cutaneotrichosporon suis sp. nov., a lipolytic yeast species from food and food-related environment
More LessTwo conspecific yeast strains, which based on DNA sequence comparisons represented an undescribed species in the order Trichosporonales were isolated during two independent studies in Hungary and France. One of them (NCAIM Y.02224) was recovered from minced pork in Hungary while the other one (UBOCC-A-218003) was isolated from the air of a dairy plant in France. The two strains shared identical nucleotide sequences in the D1/D2 domain of the nuclear large subunit (LSU) rRNA gene and in the internal transcribed spacer (ITS) region. Analysis of the concatenated DNA sequences for the ITS region and D1/D2 domain of the LSU rRNA gene indicated that the novel species belongs to the recently erected genus Cutaneotrichosporon. According to sequence comparisons and phylogenetic analysis, the novel species is most closely related to Cutaneotrichosporon curvatum (formerly Cryptococcus curvatus), which is often associated with humans and warm-blooded animals. The physiological characteristics of this novel species are also very similar to that of Cutaneotrichosporon curvatum. The only clear-cut difference is that, unlike C. curvatum, the novel species does not utilize imidazole as a nitrogen-source. The species name Cutaneotrichosporon suis sp. nov. is proposed to accommodate the above-noted two strains.

Clarifying the definition and role of effective publication in the International Code of Nomenclature of Prokaryotes with proposals to make changes
More LessThe term effective publication and the adjectival form effectively published occur at numerous points in the International Code of Nomenclature of Prokaryotes. As defined in Rule 25a the term refers to a form of publication rather than to names or descriptions. Although names are also defined as being effectively published, which is also defined as a status under the International Code of Nomenclature of Prokaryotes, such names are not automatically validly published and only validly published names can have a status under the Code. If one clearly separates the act of publication of scientific works from other elements of the Code then it is possible to clarify the workings of the Code whereby only names included in scientific works that are published in accordance with Rule 25a may have a status under the Code once they are validly published. Similarly names would then be validly published or not validly published, with the latter, irrespective of where they are found, having no status under the International Code of Nomenclature of Prokaryotes.

The name Bradyrhizobiaceae Garrity et al. 2006 contains Nitrobacter Winogradsky 1892 (Approved Lists 1980), the nomenclatural type of the family Nitrobacteraceae Buchanan 1917 (Approved Lists 1980), is illegitimate and proposals to alter the wording of Rule 54 of the International Code of Nomenclature of Prokaryotes to clarify the fact that the family name Bradyrhizobiaceae Garrity et al. 2006 is replaced by the family name Nitrobacteraceae Buchanan 1917 (Approved Lists 1980) the only correct name
More LessThe new name at the rank of family Bradyrhizobiaceae Garrity et al. 2006 was created to include the genera Afipia Brenner et al. 1992, Agromonas Ohta and Hattori 1985, Blastobacter Zavarzin 1961 (Approved Lists 1980), Bosea Das et al. 1996, Bradyrhizobium Jordan 1982 (the nomenclatural type), Nitrobacter Winogradsky 1892 (Approved Lists 1980), Oligotropha Meyer et al. 1994, Rhodoblastus Imhoff 2001 and Rhodopseudomonas Czurda and Maresch 1937 (Approved Lists 1980). However, Nitrobacter Winogradsky 1892 (Approved Lists 1980) is the nomenclatural type of Nitrobacteraceae Buchanan 1917 (Approved Lists 1980) a name at the rank of family that was validly published prior to the valid publication of Bradyrhizobiaceae Garrity et al. 2006 and has priority. In addition Rule 51b (1) of the International Code of Nomenclature of Prokaryotes rules that under these circumstances Bradyrhizobiaceae Garrity et al. 2006 is an illegitimate name. Illegitimate names may not be used (Rule 51a) and illegitimate names are also not taken into consideration when determining priority (Rule 23a). Nitrobacteraceae Buchanan 1917 (Approved Lists 1980) is the only correct name (Rule 23a). Despite these facts the name Bradyrhizobiaceae Garrity et al. 2006 continues to be used, perhaps because the fact that it is an illegitimate name and the consequences of that status are not fully understood. A revision of Rule 54 would also appear to be appropriate in order to further emphasise the fact that the family name Bradyrhizobiaceae Garrity et al. 2006 must be replaced by the family name Nitrobacteraceae Buchanan 1917 (Approved Lists 1980), which is the oldest legitimate name and is the only correct name that may be used for the taxon that includes Bradyrhizobium Jordan 1982 and Nitrobacter Winogradsky 1892 (Approved Lists 1980).

Arachnia propionica (Buchanan and Pine 1962) Pine and Georg 1969 (Approved Lists 1980), Propionibacterium propionicum corrig. (Buchanan and Pine 1962) Charfreitag et al. 1988 and Pseudopropionibacterium propionicum (Buchanan and Pine 1962) Scholz and Kilian 2016 and the nomenclatural consequences of changes in the taxonomy of the genus Propionibacterium
More LessIn a recent publication dealing with the classification of species assigned to the genus Propionibacterium , evidence was presented supporting that it would be appropriate to sub-divide the genus into four genera, Propionibacterium Orla-Jensen 1909 (Approved Lists 1980) emend. Scholz and Kilian 2016, Acidipropionibacterium Scholz and Kilian 2016, Cutibacterium Scholz and Kilian 2016 and Pseudopropionibacterium Scholz and Kilian 2016. Of these genera, Pseudopropionibacterium Scholz and Kilian 2016 was proposed to contain a single species Pseudopropionibacterium propionicum (Buchanan and Pine 1962) Scholz and Kilian 2016 that is also the nomenclatural type. The nomenclatural type of Pseudopropionibacterium propionicum (Buchanan and Pine 1962) Scholz and Kilian 2016 is also the nomenclatural type of Propionibacterium propionicum corrig. (Buchanan and Pine 1962) Charfreitag et al. 1988 and Arachnia propionica (Buchanan and Pine 1962) [Pine and Georg 1969 (Approved Lists 1980)] and are consequently homotypic synonyms. Arachnia propionica (Buchanan and Pine 1962) Pine and Georg 1969 (Approved Lists 1980) was the nomenclatural type and only species placed within the genus Arachnia Pine and Georg 1969 (Approved Lists 1980). In the light of this fact, the consequences for the names Arachnia propionica (Buchanan and Pine 1962) Pine and Georg 1969 (Approved Lists 1980), Propionibacterium propionicum corrig. (Buchanan and Pine 1962) Charfreitag et al. 1988 and Pseudopropionibacterium propionicum (Buchanan and Pine 1962) Scholz and Kilian 2016 are discussed together with the correct name for the recently validly published name Pseudopropionibacterium rubrum Saito et al. 2018.

The status of names whose nomenclatural types are based on strains deposited solely for patent purposes
More LessThe International Code of Nomenclature of Prokaryotes specifically forbids the use of strains deposited solely for patent purposes from serving as nomenclatural types. Despite this ruling there are a number of names at the rank of species where strains deposited solely for patent purposes have been designated as the nomenclatural type. In some cases there is only a single deposit where the strain is deposited solely for patent purposes or there are two or more deposits in culture collections, one (or more) of which is a strain deposited solely for patent purposes. In such instances the requirements of Rule 30 may not be fulfilled and the valid publication of the corresponding names called into question because nomenclatural types have not been deposited in at least two publicly accessible culture collections in different countries.

The role of incorrect citation of the International Code of Nomenclature of Prokaryotes and subsequent misinterpretation in causing unnecessary nomenclatural confusion
More LessThe list that notifies names published in volume 68, part 1 of the International Journal of Systematic and Evolutionary Microbiology provides the information that a number of names of species in the genus Clavibacter that had previously been treated as names at the rank of subspecies were illegitimate because they contravene Rule 34a and Rule 50a of the International Code of Nomenclature of Prokaryotes. Rule 34a deals with combinations at the same rank and this rule does not apply to names that involve a change in rank. Rule 34a, b and c all fall under the heading new combinations and that in the case of names at the rank of species and subspecies where a change in rank is made Rule 34c applies. Rule 50a applies to names at the rank of subspecies that are elevated to species, but it is unclear why these nomenclatural changes lead to illegitimate names. Fortunately the Code is explicit in stating the role of the Notification Lists is limited to allowing orthographic corrections to be made. It is necessary to publish an interpretation of the status of these names that is consistent with the current wording of the Code.
