During a study assessing the diversity of the Bacillus pumilus group it became apparent that the type strains of both Bacillus aerophilus and Bacillus stratosphericus were not available from any established culture collection, nor from the authors who originally described them. Therefore, type strains of these species cannot be included in any further scientific studies. It is therefore proposed that the Judicial Commission of the International Committee of Systematics of Prokaryotes place the names Bacillus aerophilus and Bacillus stratosphericus on the list of rejected names, if suitable replacements for the type strains are not found or if neotype strains are not proposed within two years following the publication of this Request for an Opinion.

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 assessing the diversity of the species Bacillus licheniformis, it became apparent that the type strain of Bacillus aerius was not available from any established culture collection or from the authors who originally described it. Other authors have reported similar findings when trying to obtain the strain (Lai et al., 2014), therefore, this species cannot currently be included in any further scientific studies. It is proposed that, if suitable replacements for type strains are not found or neotype strains are not proposed within two years following the publication of this Request for an Opinion, the Judicial Commission of the International Committee of Systematics of Prokaryotes place the name B. aerius on the list of rejected names.

The Judicial Commission affirms that the genus name Methanothrix Huser et al. 1983 and the species combination Methanothrix soehngenii Huser et al. 1983 do not contravene Rule 31a and are not to be considered as rejected names. The genus name Methanosaeta Patel and Sprott 1990 applies to the same taxon as Methanothrix Huser et al. 1983 and is therefore a later heterotypic synonym. The combinations Methanothrix thermoacetophila corrig. Nozhevnikova and Chudina 1988 and Methanothrix thermophila Kamagata et al. 1992 are considered to refer to the same taxon, a consequence of which is that Methanothrix thermophila Kamagata et al. 1992 contravenes Rule 51b and is placed on the List of Rejected Names.

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.

A novel actinobacterium, designated strain BR-34T, was isolated from rhizosphere soil of bamboo (Phyllostachys nigro var. henonis) sampled in Damyang, Korea. The strain was found to have morphological and chemotaxonomic characteristics typical of the genus Catenulispora . The strain contained iso-C16 : 0 as the major fatty acid and MK-9(H4), MK-9(H6) and MK-9(H8) as major isoprenoid quinones. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain BR-34T formed a cluster separate from members of the genus Catenulispora and was related most closely to Catenulispora acidiphila ID139908T (97.4 % similarity), Catenulispora rubra Aac-30T (97.3 %), Catenulispora yoronensis TT N02-20T (97.3 %) and Catenulispora subtropica TT 99-48T (97 %). However, the level of DNA–DNA relatedness between strain BR-34T and C. acidiphila ID139908T was only 45.32 %. Based on DNA–DNA relatedness, morphological and phenotypic data, strain BR-34T could be distinguished from the type strains of phylogenetically related species. It is therefore considered to represent a novel species of the genus Catenulispora , for which the name Catenulispora graminis sp. nov. is proposed. The type strain is BR-34T ( = KACC 15070T = NBRC 107755T).

Strain IK-1T was isolated from decaying tissues of the shrub Wikstroemia oahuensis collected on O‘ahu, Hawai‘i. Cells were rods that stained Gram-negative. Gliding motility was not observed. The strain was oxidase-negative and catalase-positive. Zeaxanthin was the major carotenoid. Flexirubin-type pigments were not detected. The most abundant fatty acids in whole cells of IK-1T grown on R2A were iso-C15 : 0 and one or both of C16 : 1ω7c and C16 : 1ω6c. Based on comparisons of the nucleotide sequence of the 16S rRNA gene, the closest neighbouring type strains were Flavobacterium rivuli WB 3.3-2T and Flavobacterium subsaxonicum WB 4.1-42T, with which IK-1T shares 93.84 and 93.67 % identity, respectively. The G+C content of the genomic DNA was 44.2 mol%. On the basis of distance from its nearest phylogenetic neighbours and phenotypic differences, the species Flavobacterium akiainvivens sp. nov. is proposed to accommodate strain IK-1T ( = ATCC BAA-2412T = CIP 110358T) as the type strain. The description of the genus Flavobacterium is emended to reflect the DNA G+C contents of Flavobacterium akiainvivens IK-1T and other species of the genus Flavobacterium described since the original description of the genus.

Enrichment cultures inoculated with hydrothermally influenced nearshore sediment from Papua New Guinea led to the isolation of an arsenic-tolerant, acidophilic, facultatively aerobic bacterial strain designated PNG-AprilT. Cells of this strain were Gram-stain-negative, rod-shaped, motile and did not form spores. Strain PNG-AprilT grew at temperatures between 4 °C and 40 °C (optimum 30–37 °C), at pH 3.5 to 8.3 (optimum pH 5–6) and in the presence of up to 2.7 % NaCl (optimum 0–1.0 %). Both arsenate and arsenite were tolerated up to concentrations of at least 0.5 mM. Metabolism in strain PNG-AprilT was strictly respiratory. Heterotrophic growth occurred with O2 or nitrate as electron acceptors, and aerobic lithoautotrophic growth was observed with thiosulfate or nitrite as electron donors. The novel isolate was capable of N2-fixation. The respiratory quinones were Q-8 and Q-7. Phylogenetically, strain PNG-AprilT belongs to the genus Burkholderia and shares the highest 16S rRNA gene sequence similarity with the type strains of Burkholderia fungorum (99.8 %), Burkholderia phytofirmans (98.8 %), Burkholderia caledonica (98.4 %) and Burkholderia sediminicola (98.4 %). Differences from these related species in several physiological characteristics (lipid composition, carbohydrate utilization, enzyme profiles) and DNA–DNA hybridization suggested the isolate represents a novel species of the genus Burkholderia , for which we propose the name Burkholderia insulsa sp. nov. The type strain is PNG-AprilT ( = DSM 28142T = LMG 28183T).

Parvularcula flava was proposed as a novel member of genus Parvularcula in 2016. Some time earlier, Aquisalinus flavus has been proposed as a novel species of a novel genus named Aquisalinus . When comparing the 16S rRNA gene sequences of type strains P. flava NH6-79T and A. flavus D11M-2T, they showed 97.9 % sequence identity, much higher than the sequence identities 92.7–94.3 % between P. flava NH6-79T and type strains in the genus Parvularcula , indicating that the later proposed novel taxon Parvularcula flava need reclassification. The phylogenetic trees based on 16S rRNA gene sequences and genome sequences both showed that P. flava NH6-79T and A. flavus D11M-2T formed a separated branch away from strains in the genera Parvularcula , Marinicaulis and Amphiplicatus . The average amino acid identity and average nucleotide identity values of P. flava NH6-79T and A. flavus D11M-2T were 87.9 and 85.0 %, respectively, much higher than the values between P. flava NH6-79T and other closely related type strains (54.3 %–58.1 % and 68.6–70.4 %, respectively). P. flava NH6-79T and A. flavus D11M-2T also contained summed feature 8 (C18 : 1  ω6c and/or C18 : 1  ω7c) and C16 : 0 as major fatty acids, distinguishing them from other closely related taxa. Based on the results of the phylogenetic, comparative genomic and phenotypic analyses, Parvularcula flava should be reclassified as Aquisalinus luteolus nom. nov. and the description of genus Aquisalinus is emended.

Type Strains

Three fast-growing rhizobial strains isolated from effective nodules of common vetch (Vicia sativa L.) were characterized using a polyphasic approach. All three strains were assigned to the genus Rhizobium on the basis of the results of 16S rRNA gene sequence analysis. Phylogenetic analysis based on concatenated atpD-recA genes separated the strains into a distinct lineage represented by WYCCWR 11279T, which showed average nucleotide identity values of 95.40 and 93.61 % with the most similar phylogenetic type strains of Rhizobium sophorae CCBAU 03386T and Rhizobium laguerreae FB TT, respectively. The digital DNA–DNA hybridization relatedness values between WYCCWR 11279T and the closest related type strains were less than 70 %. Therefore, a novel rhizobial species is proposed, Rhizobium changzhiense sp. nov., and strain WYCCWR 11279T (=HAMBI 3709T=LMG 31534T) is designated as the type strain for the novel species.
