In June 2000, we isolated an unknown bacterium (strain KMM 3674T) from a marine bottom sediment sample collected at a depth of 3 m in Troitsa Bay in the Gulf of Peter the Great, Sea of Japan. Polyphasic taxonomic study of the phenotypic, chemotaxonomic and genotypic characteristics and phylogenetic position of strain KMM 3674T cultured on Marine Agar 2216 (Difco) that is presented in this work indicates that this isolate is a member of the family Flavobacteriaceae and belongs to a novel species of the genus Arenibacter, for which the name Arenibacter troitsensis sp. nov. is proposed.
Flexirubin pigments were determined by the method of Fautz & Reichenbach (1980)
. Degradation of alginic acids (1 %, w/v) and agar (1·5 %, w/v), growth at different temperatures, NaCl concentrations or pH, production of acid from carbohydrates and hydrolysis of starch, casein, chitin, gelatin, cellulose (CM-cellulose and filter paper), DNA and urea were carried out according to Smibert & Krieg (1994)
. To examine carbon source utilization, a medium that contained 0·2 g NaNO3, 0·2 g NH4Cl, 0·05 g yeast extract (Difco) and 0·4 % (w/v) carbon source (l artificial sea water)-1 was used. Carbon sources tested were arabinose, glucose, lactose, mannose, sucrose, inositol, sorbitol, mannitol, fumarate, citrate and malonate. Susceptibility to antibiotics was examined by the plate diffusion method. Discs were impregnated with the following antibiotics: ampicillin (10 µg), benzylpenicillin (10 µg), carbenicillin (100 µg), gentamicin (10 µg), kanamycin (30 µg), lincomycin (15 µg), neomycin (30 µg), oleandomycin (15 µg), polymyxin B (300 U), streptomycin (10 µg) and tetracycline (30 µg).
To determine whole-cell fatty acid profiles, bacteria were grown at 28 °C for 48 h on Marine Agar 2216 (Difco). Analysis of fatty acid methyl esters was performed by GLC [30 mx0·25 mm Supelcowax 10 column (Sigma), 205 °C] as described by Svetashev et al. (1995)
. Isoprenoid quinones were extracted and analysed by the method of Nakagawa & Yamasato (1993)
. Genomic DNA was isolated by the method of Marmur (1961)
and the G+C content of the DNA was determined by the thermal denaturation method (Marmur & Doty, 1962
). The 16S rDNA sequence of strain KMM 3674T was determined by PCR amplification and direct sequencing (Hiraishi, 1992
), using conditions and reagents that were described previously (Suzuki et al., 2001
). The determined sequence was added to an alignment based on a secondary-structure model, maintained by the small-subunit rRNA database (Van de Peer et al., 2000
), by using the profile alignment program of the CLUSTAL W software (Thomson et al., 1994
). Evolutionary distances were computed with the DNADIST program in the PHYLIP 3.572 package (Felsenstein, 1995
) by using the Kimura two-parameter model (Kimura, 1980
) and a phylogenetic tree was constructed by using the neighbour-joining method (Saitou & Nei, 1987
). To evaluate the tree, bootstrap analysis with 1000 sample replications was performed with the SEQBOOT and CONSENSE programs in the PHYLIP 3.572 package.
Strain KMM 3674T was Gram-negative, chemo-organotrophic with a respiratory type of metabolism, non-motile, non-spore-forming and occurred as single flexible rods, 0·40·7 µm wide and 35 µm long. On Marine Agar 2216, colonies were round with entire edges, 13 mm in diameter, dark orange, low convex and shiny. The bacterium was oxidase-, catalase- and alkaline phosphatase-positive and required Na+ for growth (Table 1
). Growth occurred in media that contained 16 % NaCl. The temperature range for growth was 1042 °C and optimum growth occurred at 30 °C. The pH range for growth was 5·510·0 and optimum growth occurred between pH 7·5 and 8·5. No flexirubin pigments were formed. Gelatin and Tween 40 were degraded. Agar, starch, alginate, DNA, cellulose (CM-cellulose and filter paper), chitin, casein, urea, Tween 20, Tween 60 and Tween 80 were not hydrolysed. The organism produced H2S but did not produce indole or acetoin (VogesProskauer reaction) and formed no acid from arabinose, galactose, glucose, lactose, maltose, melibiose, rhamnose, sucrose, xylose, adonitol, dulcitol, inositol or mannitol. The bacterium utilized arabinose, glucose, lactose, mannose and sucrose. Utilization of inositol, mannitol, sorbitol, citrate, fumarate and malonate as sole carbon sources was not observed. Nitrate reduction was positive. The strain was susceptible to oleandomycin, lincomycin and tetracycline and resistant to ampicillin, benzylpenicillin, carbenicillin, kanamycin, streptomycin, gentamicin, neomycin and polymyxin B. Predominant cellular fatty acids were straight-chain saturated and monounsaturated or branched-chain saturated and unsaturated fatty acids, namely C15 : 0 (29·0 %), C16 : 1
7 (9·6 %), i-C15 : 0 (8·5 %), i-C15 : 1 (18·1 %) and i-C17 : 1 (5·8 %). The major isoprenoid quinone was MK-6. The G+C content of the DNA was 40·0 mol% (as determined by the thermal denaturation method).

Thus, we propose that strain KMM 3674T should be placed in the genus Arenibacter as Arenibacter troitsensis sp. nov.

Oxidase-, catalase- and alkaline phosphatase-positive. Colonies are circular, low convex, shiny with entire edges and 13 mm in diameter on Marine Agar 2216. Dark orange, non-diffusible pigments are produced. No growth is observed without Na+. Growth occurs at 16 % NaCl. Flexirubin pigments are absent. Growth occurs at 1042 °C. Gelatin and Tween 40 are degraded. Agar, casein, starch, alginic acids, cellulose (CM-cellulose and filter paper), chitin, urea, Tween-20 and Tween-80 are not hydrolysed. No acid is formed from arabinose, galactose, glucose, lactose, maltose, melibiose, rhamnose, sucrose, xylose, adonitol, dulcitol, glycerol, inositol or mannitol. Arabinose, glucose, lactose, mannose and sucrose are utilized as sole sources of carbon and energy. Utilization of inositol, mannitol, sorbitol, citrate, fumarate and malonate is not observed. Nitrate reduction and H2S production are positive. Indole and acetoin (VogesProskauer reaction) are not produced. Susceptible to oleandomycin, lincomycin and tetracycline. Resistant to ampicillin, carbenicillin, kanamycin, benzylpenicillin, neomycin, streptomycin, gentamicin and polymyxin B. Predominant cellular fatty acids are C15 : 0, i-C15 : 1, i-C15 : 0, C16 : 1
