    Abstract: Two enterobacterial strains, designated YMB-R21 T and YMB-R22, were isolated from larvae of mealworm Tenebrio molitor L. and examined for their taxonomic characteristics. A 16S rRNA gene-based neighbour-joining tree showed that the two isolates formed two distinct sublineages within the family Enterobacteriaceae and were separated from other genera of the family. The isolates showed 16S rRNA gene sequence similarity of 98.9 % to each other and ≤96.5 % to members of the order Enterobacteriales . The phylogenomic analysis based on 92 singly-copy core genes showed that the two isolates belonged to the family Enterobacteriaceae and formed a distinct sublineage at a position located remotely from the genera of the family. The loosely associated members were the type strain of Erwinia teleogrylli and members of the genus Shimwellia . Average nucleotide identity and digital DNA–DNA hybridization values showed that the isolates represented members of a novel species in the family Enterobacteriaceae . The values of amino acid identity between the two isolates and the closest relatives were 74.5–75.0 % with the type strain of E. teleogrylli and 74.5–74.8 % with the type strains of two Shimwellia species, while E. teleogrylli showed the amino acid identity values of 76.3–76.5 % with two Shimwellia species. Based on the results obtained here, we propose a new genus Tenebrionicola with the description of Tenebrionicola larvae sp. nov. (type strain YMB-R21 T =KCTC 82597 T =CCM 9152 T and strain YMB-R22=KCTC 82598=CCM 9153), with the transfer of Erwinia teleogrylli Liu et al . 2016 to a new genus Entomohabitans as Entomohabitans teleogrylli comb. nov. (type strain SCU-B244 T =CGMCC 1.12772 T =DSM 28222 T =KCTC 42022 T ).

    Abstract: A Gram-reaction-positive, strictly aerobic, non-sporulating, non-motile, rod-shaped bacterium, designated YC3-14 T , was isolated from pieces of stalagmite collected in a lava cave in Jeju, Republic of Korea. Cells showed growth at 15–35 °C, pH 6.0–9.0 and with 0–3 % (w/v) NaCl. Colonies of the cells were circular, smooth, convex and cream in colour. A 16S rRNA gene-based neighbour-joining tree indicated that the organism belonged to the genus Aeromicrobium and formed a sublineage between an Aeromicrobium endophyticum–Aeromicrobium fastidiosum cluster and an Aeromicrobium yanjiei–Aeromicrobium chenweiae cluster. The highest 16S rRNA gene similarity values of strain YC3-14 T were with the type strains of A. yanjiei (99.2 %), A. endophyticum (99.1 %), A. fastidiosum (98.8 %), A. ginsengisoli (98.8 %) and A . chenweiae (98.7 %). The cell-wall peptidoglycan contained ll -diaminopimelic acid as the diagnostic diamino acid. The major menaquinone was MK-9(H 4 ). The predominant fatty acids were C 18 : 0 .10-methyl, C 18 : 1  ω 9 c and C 16 : 0 . The polar lipids comprised diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, an unidentified phospholipid and two unidentified lipids. The G+C content of the genome DNA was 69.9 mol%. These chemotaxonomic features of the isolate were typical for the genus Aeromicrobium . The genome-based phylogeny showed the same tree topology as the 16S rRNA gene phylogeny. The average nucleotide identity (≤84.5 %) and digital DNA–DNA hybridization (≤27.5 %) values supported that the isolate belongs to a novel species of the genus Aeromicrobium . On the basis of data obtained by a polyphasic approach, strain YC3-14 T (=KCTC 49469 T =NBRC 114653 T ) represents a novel species of the genus Aeromicrobium , for which the name Aeromicrobium stalagmiti sp. nov. is proposed.

    Abstract: Two Gram-positive bacterial strains, designated as YMB-B2 T and BWT-G7 T , were isolated from larvae of Tenebrio molitor L. and Allomyrina dichotoma , respectively, and their taxonomic positions examined by a polyphasic approach. Both of the isolates contained ornithine as the cell-wall diamino acid. The acyl type of murein was N -glycolyl. The predominant menaquinones were MK-11 and MK-12. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol and an unidentified glycolipid. Both of the isolates contained C 15 : 0 anteiso and C 17 : 0 anteiso as the major fatty acids. Strain YMB-B2 T also had C 16 : 0 iso as an additional major fatty acid. The 16S rRNA gene phylogeny showed that the novel strains formed two distinct sublines within the genus Microbacterium . Strain YMB-B2 T was most closely related to the type strains of Microbacterium aerolatum (99.1 % sequence similarity) and Microbacterium ginsengiterrae (99.0 %) , whereas strain BWT-G7 T formed a tight cluster with the type strain of Microbacterium thalassium (98.9 %). The phylogenomic analysis based on 92 core genes supported their relationships in 16S rRNA gene phylogeny. Overall genomic relatedness indices warranted that the isolates represent two new species of the genus Microbacterium . Based on the results obtained here, Microbacterium tenebrionis sp. nov. (type strain YMB-B2 T =KCTC 49593 T =CCM 9151 T ) and Microbacterium allomyrinae sp. nov. (type strain BWT-G7 T =KACC 22262 T =NBRC 115127 T ) are proposed.

    Abstract: A Gram-reaction-positive, strictly aerobic, catalase-positive, oxidase-negative, non-motile actinobacterium, designated C1-24 T , was isolated from a soil sample collected inside a natural cave. The organism exhibited a rod–coccus developmental cycle during its growth phase. Results of 16S rRNA gene-based phylogenetic analysis showed that the novel strain belonged to the genus Rhodococcus and formed a distinct sublineage at the base of the radiation including a Rhodococcus enclensis–Rhodococcus kroppenstedtii–Rhodococcus corynebacterioides–Rhodococcus trifoli cluster. In the results of phylogenomic analysis, the novel strain was loosely associated to Rhodococcus corynebacterioides . The closest relatives were Rhodococcus qingshengii (98.01 % 16S rRNA gene sequence similarity) and Rhodococcus degradans (98.01 %). The genome size was 5.66 Mbp and the DNA G+C content was 64.30 mol%. Whole-cell hydrolysates contained meso -diaminopimelic acid, arabinose and galactose as the diagnostic diamino acid and sugars. MK-8(H 2 ) was the predominant menaquinone. The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, an unidentified glycolipid and three unidentified phospholipids. Mycolic acids were present. The major fatty acids were C 16 : 0 , C 18 : 1   ω9 c , C 16 : 1   ω7 c and/or C 16 : 1   ω6 c and 10-methyl C 18 : 0 . Digital DNA–DNA hybridization and average nucleotide identity values revealed that the novel strain should be assigned to a different species. Based on the combined data obtained here, strain C1-24 T (=KACC 19964 T =DSM 109484 T ) represents a new species of the genus Rhodococcus , for which Rhodococcus cavernicola sp. nov. is proposed. Also, it is proposed that R. degradans is a later heterosynonym of R. qingshengii based on analyses of 16S rRNA gene and whole-genome sequences.

    Abstract: Two Gram-stain-positive, strictly aerobic, non-spore-forming actinobacterial strains, designated YC2-7 T and YC5-17, were isolated from the Yongcheondonggul (larva cave) in Jeju, Republic of Korea and their taxonomic ranks were examined by a polyphasic approach. The 16S rRNA gene tree showed that the novel isolates occupied an independent position separated from recognized genera of the family Nocardiaceae . In the 92 core gene-based phylogenomic analysis, strain YC2-7 T was loosely associated with the type strain of Aldersonia kummingensis with 66.2 % average amino acid identity. The 16S rRNA gene sequence simairity between the isolate and members of the family Nocardiaceae was below 96.7 %. The cell-wall peptidoglycan was meso-diaminopimelic acid as a diagnostic diamino acid. Whole-cell sugars consisted of arabinose, galactose and glucose. The predominant menaquinone was MK-8(H4, ω-cycl). The major polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and phosphatidylinositol mannoside. The cellular fatty acids consisted mainly of saturated and unsaturated components with small amounts of tuberculostearic acid. Mycolic acids of 52–58 carbon atoms were present. The DNA G+C content of the genome was 63.8 mol%. On the basis of combination of morphological and chemotaxonomic differences, in addition to phylogenetic distinctness, the novel isolates are considered to constitute members of a novel species of a new genus in the family Nocardiaceae , for which the name Antrihabitans stalactiti gen. nov., sp. nov. is proposed. The type strain is YC2-7 T (=KACC 19965 T =DSM 108733 T ).

    Abstract: Taxonomic positions of four Gram-negative bacterial strains, which were isolated from larvae of two insects in Jeju, Republic of Korea, were determined by a polyphasic approach. Strains CWB-B4, CWB-B41 and CWB-B43 were recovered from larvae of Protaetia brevitarsis seulensis , whereas strain BWR-B9 T was from larvae of Allomyrina dichotoma . All the isolates grew at 10–37 °C, at pH 5.0–9.0 and in the presence of 4 % (w/v) NaCl. The 16S rRNA gene phylogeny showed that the four isolates formed two distinct sublines within the order Enterobacteriales and closely associated with members of the genus Jinshanibacter . The first group represented by strain CWB-B4 formed a tight cluster with Jinshanibacter xujianqingii CF-1111 T (99.3 % sequence similarity), whereas strain BWR-B9 T was most closely related to Jinshanibacter zhutongyuii CF-458 T (99.5 % sequence similarity). The 92 core gene analysis showed that the isolates belonged to the family Budviciaceae and supported the clustering shown in 16S rRNA gene phylogeny. The genomic DNA G+C content of the isolates was 45.2 mol%. A combination of overall genomic relatedness and phenotypic distinctness supported that three isolates from Protaetia brevitarsis seulensis are different strains of Jinshanibacter xujianqingii , whereas one isolate from Allomyrina dichotoma represents a new species of the genus Jinshanibacter . On the basis of results obtained here, Jinshanibacter allomyrinae sp. nov. (type strain BWR-B9 T =KACC 22153 T =NBRC 114879 T ) and Insectihabitans xujianqingii gen. nov., comb. nov. are proposed, with the emended descriptions of the genera Jinshanibacter , Limnobaculum and Pragia .

    Abstract: A novel marine bacterium, strain KMM 6050 T , was isolated from the sea urchin Strongylocentrotus intermedius , which inhabits the Sea of Japan. The strain studied was strictly aerobic, heterotrophic, yellow–orange-pigmented, motile by gliding, Gram-negative and oxidase-, catalase-, β -galactosidase- and alkaline phosphatase-positive. The results of 16S rRNA gene sequence analysis showed that strain KMM 6050 T occupies a distinct lineage within the family Flavobacteriaceae and is most closely related to the species Mesonia algae and Salegentibacter salegens (sequence similarity of 92·5–92·6 %). The DNA G+C content of KMM 6050 T was 39·6 mol%. The major respiratory quinone was MK-6. The predominant fatty acids were i15 : 0, a15 : 0, 15 : 0, i16 : 1, i16 : 0, i16 : 0 3-OH and i17 : 0 3-OH. On the basis of phenotypic, chemotaxonomic, genotypic and phylogenetic characteristics, the novel bacterium has been assigned to the genus Gramella gen. nov., as Gramella echinicola sp. nov. The type strain is KMM 6050 T (=KCTC 12278 T =NBRC 100593 T =LMG 22585 T ).
