    Abstract: A polyphasic taxonomic approach was used to characterize two novel bacterial strains, designated as HDW11 T and HDW19 T , isolated from intestine samples of the dark diving beetle Hydrophilus acuminatus and the diving beetle Cybister lewisianus , respectively. Both isolates were Gram-stain-positive, facultatively anaerobic and non-motile. Strain HDW11 T grew optimally at 30 °C, pH 8 and in the presence of 1% (w/v) NaCl. Strain HDW19 T grew optimally at 25 °C, pH 7 and in the presence of 0.3% (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences and genome sequences revealed that strain HDW11 T is a member of the genus Brevilactibacter and is closely related to Brevilactibacter flavus VG341 T [with 97.9% 16S rRNA sequence identity and 79.1% average nucleotide identity (ANI)], and that strain HDW19 T belongs to the genus Weissella and is closely related to W. koreensis KCTC 3621 T (with 98.9% 16S rRNA sequence identity and 79.5% ANI). The major cellular fatty acids of strains HDW11 T and HDW19 T were C 18:1 ω 9c and anteiso-C 15:0 , respectively. The sole respiratory quinone of strain HDW11 T was MK-9 (H 4 ). The major polar lipid components of strain HDW11 T were diphosphatidylglycerol and phosphatidylglycerol, and the major polar lipid component of strain HDW19 T was diphosphatidylglycerol. The genomic DNA G+C content of strains HDW11 T and HDW19 T were 72.1 and 37.2 mol%, respectively. The results of phylogenetic, phenotypic, chemotaxonomic and genotypic analyses suggest that strain HDW11 T represents a novel species within the genus Brevilactibacter , and that strain HDW19 T represents a novel species within the genus Weissella . We propose the name Brevilactibacter coleopterorum sp. nov. for strain HDW11 T (=KACC 21335 T =KCTC 49320 T =JCM 33680 T ) and the name Weissella coleopterorum for strain HDW19 T (=KACC 21347 T =KCTC 43114 T =JCM 33684 T ).

    Abstract: A polyphasic taxonomic approach was used to characterize a novel bacterium, designated as strain HDW20 T , isolated from the intestine of the dark diving beetle Hydrophilus acuminatus . The isolate was Gram-stain-positive, facultatively anaerobic, non-motile, coccus-shaped, and formed pale orange colonies. Phylogenetic analysis based on 16S rRNA gene sequences and genome sequences showed that the isolate belonged to the genus Tessaracoccus in the phylum Actinobacteria and was closely related to T. flavescens SST-39 T , T. defluvii JCM 17540 T , and T. aquimaris NSG39 T , with the highest 16S rRNA gene sequence similarity of 98.5 % and a highest average nucleotide identity (ANI) value of 80.6 %. The major cellular fatty acids were C 18 : 1  ω 9 c and anteiso-C 15 : 0 . The main respiratory quinone was MK-9 (H 4 ). The major polar lipid components were phosphatidylglycerol and diphosphatidylglycerol. The genomic DNA G+C content was 69.0 %. The isolate contains ʟʟ-diaminopimelic acid, ʟ-alanine, and ʟ-lysine as amino acid components, and ribose, glucose, and galactose as sugar components of the cell wall peptidoglycan. The results of phylogenetic, phenotypic, chemotaxonomic, and genotypic analyses suggested that strain HDW20 T represents a novel species within the genus Tessaracoccus . We propose the name Tessaracoccus coleopterorum sp. nov. The type strain is HDW20 T (=KACC 21348 T =KCTC 49324 T =JCM 33674 T ).

    Parasphingorhabdus cellanae sp. nov., isolated from the gut of a Korean limpet, Cellana toreuma

    Abstract: A novel bacterium, designated strain JHSY0214 T , was isolated from the gut of a Korean limpet, Cellana toreuma . Cells of strain JHSY0214 T were Gram-stain-negative, strictly aerobic, yellow-pigmented, non-spore-forming, non-motile and showed a rod–coccus growth cycle. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain belonged to the genus Parasphingorhabdus , and was most closely related to Parasphingorhabdus litoris KCTC 12764 T (98.71 %). Strain JHSY0214 T had two fluoroquinolone-resistance genes and seven multidrug-resistance efflux pump genes, but did not have beta-lactamase genes and zinc resistance genes compared with P. litoris KCTC 12764 T . Strain JHSY0214 T grew optimally at 30 °C, pH 7.0 and in the presence of 2 % (w/v) NaCl. The predominant cellular fatty acids of strain JHSY0214 T were summed feature 8 (C 18 : 1  ω 6 c and/or C 18 : 1  ω 7 c ; 41.2 %), summed feature 3 (C 16 : 1  ω 7 c and/or C 16 : 1  ω 6 c ; 21 %) and C 16 : 0 (18.9 %). The major isoprenoid quinone was ubiquinone-10. The major polar lipids were sphingoglycolipid and phosphatidylethanolamine. The genomic DNA G+C content was 52.8 mol%. Based on phylogenetic, genotypic and phenotypic data, strain JHSY0214 T represents a novel species of the genus Parasphingorhabdus , for which the name Parasphingorhabdus cellanae is proposed. The type strain is JHSY0214 T (=KCTC 82387 T =DSM 112279 T ).

    Chitinibacter bivalviorum sp. nov., isolated from the gut of the freshwater mussel Anodonta arcaeformis

    Abstract: A novel Gram-stain-negative, aerobic, rod-shaped bacterium with a single polar flagellum, designated strain 2T18 T , was isolated from the gut of the freshwater mussel Anodonta arcaeformis collected in the Republic of Korea. Phylogenetic analyses based on 16S rRNA gene sequences showed that the strain belonged to the genus Chitinibacter . Strain 2T18 T formed a monophyletic clade with Chitinibacter fontanus KCTC 42982 T , C. tainanensis KACC 11706 T and C. alvei KCTC 23839 T , with sequence similarities of 98.5, 98.4 and 95.9 %, respectively. Strain 2T18 T exhibited optimal growth at 30 °C, at pH 8 and with 0.5 % (w/v) NaCl. The major isoprenoid quinone was ubiquinone-8 (Q-8). The predominant fatty acids were summed feature 3 (C 16 : 1 ω 6 c and/or C 16 : 1 ω 7 c ) and C 16 : 0 . The polar lipids comprised phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, one unidentified lipid, three unidentified phospholipids and two unidentified aminophospholipids. The G+C content of the genomic DNA was 50.6 mol%. The average nucleotide identity and digital DNA–DNA hybridization values between strains 2T18 T and C. fontanus KCTC 42982 T were below the thresholds used for the delineation of a novel species. Based on the phylogenetic, phenotypic, chemotaxonomic and genotypic characteristics, strain 2T18 T represents a novel species of the genus Chitinibacter , for which the name Chitinibacter bivalviorum sp. nov. is proposed. The type strain is 2T18 T (=KCTC 72821 T =CCUG 74764 T ).
