RESUMEN
Alicyclobacillus sp. DSM 11985T was isolated from geothermal soil but had not yet been classified at the species level. The strain produced guaiacol, which is of interest from the viewpoint of food spoilage in the food industry. 16S rRNA gene sequence analysis revealed that strain DSM 11985T was closely related (99.6â% similarity) to Alicyclobacillus hesperidum DSM 12489T. However, strains of A. hesperidum did not produce guaiacol; therefore, we performed the taxonomic characterization of strain DSM 11985T. The results showed that strain DSM 11985T and strains of A. hesperidum showed different phenotypic characteristics in biochemical/physiological tests including guaiacol production. Average nucleotide identity values between strain DSM 11985T and strain DSM 12489T were 95.4-95.9â%, and the in silico DNA-DNA hybridization value using the Genome-to-Genome Distance Calculator between strains DSM 11985T and DSM 12489T was 65.5â%. These values showed that strain DSM 11985T was genetically closely related but separated from strains of A. heparidum. From the above results, a novel subspecies of A. hesperidum, named Alicyclobacillus hesperidum subsp. aegles subsp. nov. is proposed. The type strain is DSM 11985T (=FR-12T=NBRC 113041T).

A taxonomic investigation using a polyphasic method was conducted to identify a novel marine flavobacterium, designated as DJ-13T, isolated from the hard coral Acropora sp. collected at Okinawa, Japan. Bacterial cells were Gram-stain-negative, yellow-colored, strictly aerobic, rod-shaped, catalase- and oxidase-positive, non-motile, and chemoorganoheterotrophic. The novel isolate grew at NaCl concentrations of 0.5-7%, pH 6.5-9.0, and 15-37 °C. A phylogenetic study on the basis of the 16S rRNA gene sequence revealed that strain DJ-13T belongs to the family Flavobacteriaceae and that it shared the greatest sequence similarity (95.9%) with Croceivirga lutea CSW06T. Strain DJ-13T comprised iso-C17:0 3-OH, iso-C15:0, and iso-C15:1 G as the main (> 10%) cellular fatty acids. Menaquinone-6 (MK-6) was the only respiratory quinone. The assembled draft genome size of strain DJ-13T was 3.71 Mbp with G + C content of 38.7 mol%. The average nucleotide identity (ANI), digital DNA-DNA hybridization (dDDH), and average amino acid identity (AAI) values of DJ-13T and the species of the genus Croceivirga were found to be 74.9-75.5%, 13.4-14.7%, and 68.2-72.4%, respectively. Strain DJ-13T contained phosphatidylethanolamine, two unidentified aminolipids, and five unidentified lipids as polar lipids. From the polyphasic taxonomic results presented, the strain is considered to represent a novel species of the genus Croceivirga for which the name Croceivirga thetidis sp. nov. is proposed. The type strain of C. thetidis sp. nov. is DJ-13T (= KCTC 72790T = NBRC 114252T).

A novel marine flavobacterial species, designated 3KA7-17T, was isolated from the hard coral Acropora formosa D. collected in Japan. The strain was pale-orange pigmented, Gram-stain negative, strictly aerobic, coccus shaped, and non-motile. Preliminary analysis based on the 16S rRNA gene sequence revealed an affiliation with the family Flavobacteriaceae of the phylum Bacteroidetes, and it had the greatest sequence similarity (96.0%) to Seonamhaeicola algicola Gy8T. The DNA G + C content was 34.3 mol%. MK-6 was the major menaquinone, with iso-C15:1 H and/or C13:0 3-OH (24.3%), iso-C15:0 (19.5%), iso-C15:0 3-OH (14.2%), and iso-C17:0 3-OH (15.9%) as the main (> 10%) cellular fatty acids. The major polar lipid profile consisted of phosphatidylethanolamine, two unidentified aminolipids, and two unidentified lipids. Based on distinct phylogenetic and phenotypic evidence, the strain represents a novel species of the genus Seonamhaeicola, for which the name Seonamhaeicola acroporae sp. nov. is proposed and the type strain is 3KA7-17T (= KCTC 62713T = NBRC 113410T).

A polyphasic taxonomic investigation was performed on a bacterial strain, 38-Ka-2(T), which was isolated from the green alga Ulva pertusa Kjellman (Chlorophyta) in Hokkaido, Japan. The bacterial cells were observed to be golden-yellow coloured, Gram-negative, strictly aerobic, non-spore-forming, non-motile and rod-shaped. Phylogenetic analyses based on the 16S rRNA gene sequence indicated that the new strain is a member of the family Flavobacteriaceae within the phylum Bacteroidetes and that it shows high sequence similarity (94.8 %) to Aquimarina addita JC2680(T). The genomic DNA G+C content of strain 38-Ka-2(T) was determined to be 36 mol%; MK-6 was identified as the major menaquinone; and the presence of iso-C15:0, C18:0 and iso-C17:0 3-OH as the major (>10 %) cellular fatty acids. The polar lipid profile was found to consist of phosphatidylethanolamine, an unidentified glycolipid and two unidentified lipids. From the distinct phylogenetic position and combination of genotypic and phenotypic characteristics, strain 38-Ka-2(T) is considered to represent a novel genus for which the name Algitalea ulvae gen. nov., sp. nov. is proposed. The type strain of A. ulvae is 38-Ka-2(T) (=KCTC 32994(T) = NBRC 110017(T)).

A novel Gram-stain negative, spherical, non-motile, strictly aerobic, heterotrophic, yellow pigmented bacterium, designated strain 04OKA003-7(T) was isolated from the hard coral Galaxea fascicularis L. collected at Akajima, Okinawa, Japan. Phylogenetic analysis based on the 16S rRNA gene sequence revealed the novel isolate is affiliated with the family Flavobacteriaceae of the phylum Bacteroidetes and that it showed highest sequence similarity (92.9 %) to Vitellibacter aestuarii JC2436(T) and Aureitalea marina S1-66(T). The strain could be differentiated phenotypically from recognized members of the family Flavobacteriaceae. The major fatty acids of strain 04OKA003-7(T) were identified as iso-C15:0 and iso-C17:0 3-OH as defined by the MIDI system. The DNA G+C content was determined to be 41 mol%, the major respiratory quinone was identified as menaquinone 6 (MK-6) and a polar lipid profile was present consisting of phosphatidylethanolamine, two unidentified aminolipids and an unidentified lipid. From the distinct phylogenetic position and combination of genotypic and phenotypic characteristics, the strain is considered to represent a novel genus for which the name Aureisphaera galaxeae gen. nov., sp. nov. is proposed. The type strain of A. galaxeae is 04OKA003-7(T) (=KCTC 32993(T) = NBRC 110018(T)).

A Gram-negative, strictly aerobic, lemon-yellow pigmented, non-motile, rod-shaped strain designated A7G-39(T) was isolated from a yellow coloured marine sponge (Tethya sp.). Phylogenetic analyses based on the 16S rRNA gene sequence indicated that the new strain represented a member of the family Flavobacteriaceae of the phylum Bacteroidetes and that it showed highest sequence similarity (94.1 %) to Algibacter wandonensis WS-MY22(T). The strain could be differentiated phenotypically from recognised members of the family Flavobacteriaceae. The major fatty acids of strain A7G-39(T) were identified as iso-C15:0 3-OH and summed feature 1 (iso-C15:1 H and/or C13:0 3-OH) as defined by the MIDI system. The DNA G+C content was determined to be 32.6 mol%, the major respiratory quinone was identified as menaquinone 7 (MK-7) and a polar lipid profile was present consisting of phosphatidylethanolamine, an unidentified aminolipid and an unidentified lipid. From the distinct phylogenetic position and combination of genotypic and phenotypic characteristics, the strain is considered to represent a novel genus for which the name Spongiivirga citrea gen. nov., sp. nov. is proposed. The type strain of S. citrea is A7G-39(T) (=KCTC 32990(T) = NBRC 110022(T)).
