A rod-shaped marine bacterium, designated strain CL-TF09T, isolated from a tidal flat in Ganghwa, Korea, was characterized based on its physiological and biochemical features, fatty acid profile and phylogenetic position. 16S rRNA gene sequence analysis revealed a clear affiliation with the family Flavobacteriaceae. Strain CL-TF09T showed the closest phylogenetic relationship with the genera Tenacibaculum and Polaribacter; sequence similarities between CL-TF09T and the type strains of Tenacibaculum and Polaribacter species ranged from 90·7 to 91·8 %. Cells of strain CL-TF09T were non-motile and grew on solid media as yellow colonies. The strain grew in the presence of 1–5 % sea salts, within a temperature range of 5–30 °C and at pH 7–8. The strain had iso-C15 : 0 3-OH (17·4 %), iso-C15 : 0 (16·7 %), anteiso-C15 : 0 (15·1 %) and iso-C16 : 0 3-OH (13·4 %) as predominant fatty acids. The DNA G+C content was 33·9 mol%. Based on the physiological, fatty acid composition and phylogenetic data presented, strain CL-TF09T is considered to represent a novel genus and species of the family Flavobacteriaceae, for which the name Lutibacter litoralis gen. nov., sp. nov. is proposed. The type strain is CL-TF09T (=KCCM 42118T=JCM 13034T).

A Gram-stain-negative, non-motile, aerobic, ovoid or rod-shaped bacterium, designated AH-MY3T, was isolated from a tidal flat on Aphae island of the south-western sea, South Korea, and subjected to a polyphasic taxonomic study. Strain AH-MY3T grew optimally at 35 °C, at pH 7.0–8.0 and in the presence of 2.0–3.0  % (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain AH-MY3T joined the cluster comprising the type strains of Yeosuana aromativorans, Snuella lapsa and Meridianimaribacter flavus, showing sequence similarities of 93.9, 93.7 and 92.6  %, respectively. Strain AH-MY3T exhibited 16S rRNA gene sequence similarity values of 94.0–94.7  % to the type strains of ‘Aestuariibaculum scopimerae’, Winogradskyella aquimaris, Winogradskyella poriferorum and Gaetbulibacter aestuarii. Strain AH-MY3T contained MK-6 as the predominant menaquinone. The fatty acid and polar lipid profiles of strain AH-MY3T could be distinguished from those of the type strains of phylogenetically related taxa. The DNA G+C content of strain AH-MY3T was 37 mol%. The phylogenetic data and differential chemotaxonomic and other phenotypic properties revealed that strain AH-MY3T represents a novel genus and species within the family Flavobacteriaceae, for which the name Aestuariivivens insulae gen. nov., sp. nov. is proposed. The type strain of Aestuariivivens insulae is AH-MY3T ( = KCTC 42350T = NBRC 110723T).

A beige-pigmented bacterium (strain CCUG 53761AT) was isolated from human blood from an 85-year-old man in Göteborg, Sweden. Comparative analysis of 16S rRNA gene sequences showed that this bacterium displayed <95 % similarity to all described species of the genera of the family Alcaligenaceae. It grouped within the radiation of the genus Alcaligenes, but showed only 93.0–94.8 % similarity to type strains of members of this genus (Alcaligenes faecalis subsp. parafaecalis, 94.8 %; Alcaligenes faecalis subsp. faecalis, 94.2 %; Alcaligenes faecalis subsp. phenolicus, 93.4 %). This discrimination was supported by chemotaxonomic differences. The polyamine pattern consisted of the predominant compound putrescine, moderate amounts of spermidine and minor to trace amounts of spermine and cadaverine; 2-hydroxyputrescine was not detectable. The quinone system was ubiquinone Q-8 with minor amounts of Q-7. The polar lipid profile was composed of the major lipids diphosphatidylglycerol and phosphatidylethanolamine and moderate amounts of phosphatidylglycerol and an unknown phospholipid; minor lipids were also detected. The fatty acid profile, with large amounts of C16 : 0 and C17 : 0 cyclo and the absence of C12 : 0 2-OH as hydroxylated fatty acid, also differed significantly from those reported for Alcaligenes species. On the basis of these data, it is proposed that strain CCUG 53761AT represents a novel genus and species, for which the name Paenalcaligenes hominis gen. nov., sp. nov. is proposed. The type strain of Paenalcaligenes hominis is CCUG 53761AT =CCM 7698T.

A marine bacterium, designated strain KMM 6038T, was subjected to taxonomic analysis via a polyphasic approach. Cells of the strain were heterotrophic, orange-pigmented, Gram-negative and motile by means of gliding. 16S rRNA gene sequence analysis indicated that strain KMM 6038T was closely related to the type species of the genera Algibacter and Yeosuana, members of the family Flavobacteriaceae, with sequence similarities of 93.8 and 93.6 % to the respective type strains. However, several chemotaxonomic and phenotypic characteristics, such as the cellular fatty acid profile (iso-C15 : 0, anteiso-C15 : 0, iso-C15 : 1, C15 : 0, C15 : 1 ω6c, iso-C15 : 0 3-OH and iso-C17 : 0 3-OH) and the low G+C content of the DNA (35.7 mol%), indicated that the strain should be separated from these two genera. From the results of phenotypic, genotypic, chemotaxonomic and phylogenetic analyses, the bacterium should be classified as representing a novel genus and species, for which the name Mariniflexile gromovii gen. nov., sp. nov. is proposed. The type strain of Mariniflexile gromovii is KMM 6038T (=KCTC 12570T=LMG 22578T).

Two Gram-stain-negative and non-flagellated bacteria, YSTF-M3T and YSTF-M6T, were isolated from a tidal flat from Yellow Sea, Republic of Korea, and subjected to a polyphasic taxonomic study. Neighbour-joining phylogenetic tree of 16S rRNA gene sequences showed that strains YSTF-M3T and YSTF-M6T belong to the genera Kordia and Olleya of the family Flavobacteriaceae , respectively. The 16S rRNA gene sequence similarities between strain YSTF-M3T and the type strains of Kordia species and between strain YSTF-M6T and the type strains of Olleya species were 94.1–98.4 and 97.3–98.3 %, respectively. The ANI and dDDH values between genomic sequences of strain YSTF-M3T and the type strains of five Kordia species and between those of strain YSTF-M6T and the type strains of three Olleya species were in ranges of 77.0–83.2 and 20.7–27.1 % and 79.4–81.5 and 22.3–23.9 %, respectively. The DNA G+C contents of strain YSTF-M3T and YSTF-M6T from genomic sequences were 34.1 and 31.1 %, respectively. Both strains contained MK-6 as predominant menaquinone and phosphatidylethanolamine as only major phospholipid identified. Differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strains YSTF-M3T and YSTF-M6T are separated from recognized species of the genera Kordia and Olleya , respectively. On the basis of the data presented, strains YSTF-M3T (=KACC 21639T=NBRC 114499T) and YSTF-M6T (=KACC 21640T=NBRC 114500T) are considered to represent novel species of the genera Kordia and Olleya , respectively, for which the names Kordia aestuariivivens sp. nov. and Olleya sediminilitoris sp. nov. are proposed.

Six strains (CB7T, CB18, CB23, CB26, CB28 and CB35T) were isolated from human faeces. Based on phylogenetic analysis, phenotypic characteristics, cellular fatty acid profiles and menaquinone profiles, these strains could be included within the genus Prevotella and made up two clusters. 16S rRNA gene sequence analysis indicated that five strains were most closely related to Prevotella veroralis, sharing about 92 % sequence similarity; the remaining strain was most closely related to Prevotella shahii, sharing about 90 % sequence similarity. All six strains were obligately anaerobic, non-pigmented, non-spore-forming, non-motile, Gram-negative rods. The cellular fatty acid compositions of the six strains differed significantly from those of other Prevotella species. Five strains (CB7T, CB18, CB23, CB26 and CB28) contained dimethyl acetals and the major menaquinones of these strains were MK-11, MK-12 and MK-13. The major menaquinones of CB35T were MK-12 and MK-13. Based on phenotypic and phylogenetic findings, two novel species, Prevotella copri sp. nov. and Prevotella stercorea sp. nov., are proposed, representing the two different strain clusters. The DNA G+C contents of strains CB7T and CB35T were 45.3 and 48.2 mol%, respectively. The type strains of P. copri and P. stercorea are CB7T (=JCM 13464T=DSM 18205T) and CB35T (=JCM 13469T=DSM 18206T), respectively.
