Other physiological characteristics of the isolate were tested with API 20NE and API 50CH test strips (bioMérieux). API 20NE and API 50CH tests results

were observed over a period of 7 days at 25 °C. Antibiotic sensitivity was tested by spreading a bacterial suspension on R2A and applying discs impregnated with the following antibiotics (concentration per disc): BGB324 nmr ampicillin (10 μg), amikacin (30 μg), ceftriaxone (30 μg), clindamycin (2 μg), gentamicin (30 μg), kanamycin (30 μg), neomycin (30 μg), penicillin (10 μg), streptomycin (10 μg), tetracycline (30 μg) and vancomycin (30 mg). Isoprenoid quinones of strain DR-f4T were analyzed with freeze-dried cells previously grown in R2A for 3 days according to the method of Collins & Jones (1981) and Komagata & Suzuki (1987). The quinone was purified via preparative thin-layer chromatography (silica gel F254; Merck) and was identified using an HPLC (Hitachi L-5000) equipped with a reverse-phase column (YMC pack ODS-AM; YMC Co.). For fatty acid methyl esters (FAMEs) analysis, strain DR-f4T was cultured on R2A (pH 6.0) at 20 °C for 3 days, which are the same culture conditions as those used for FAMEs analysis of the closest type strain, M. lappiensis ANJL12T (Männistöet al., 2010). LY2606368 chemical structure FAMEs were extracted according to the standard protocol of the microbial identification system (MIDI;

Sasser, 1990), separated by a gas chromatograph (HP 6890N; Agilent) and identified using the sherlock software package (MIDI). Genomic DNA of strain DR-f4T and E. coli KCTC 2441T was extracted according to the method described Branched chain aminotransferase by Sambrook & Russell (2001). The G+C content of the isolate was determined using the method described by Mesbah et al. (1989). Briefly, genomic DNAs were hydrolyzed and dephosphorylated with nuclease P1 and with alkaline phosphatase, respectively, and then the mixtures of nucleosides were analyzed by HPLC for G+C mol%. The 16S rRNA gene was amplified by PCR with the universal primers 27F and 1492R (Lane, 1991). After

purification of the PCR product, the sequencing reaction of the 16S rRNA gene was performed at SolGent Co., Korea, using an ABI prism Bigdye terminator cycle sequencing ready reaction kit V.3.1 and an ABI 3730XL capillary DNA Sequencer (Applied Biosystems). The sequence of the 16S rRNA gene was assembled using vector nti software (Invitrogen). The sequence of strain DR-f4T was compared with available 16S rRNA gene sequences from the GenBank using the blast program (http://www.ncbi.nlm.nih.gov/blast/) and the EzTaxon server (http://www.eztaxon.org/; Chun et al., 2007). The 16S rRNA gene sequence of strain DR-f4T was aligned with those of representative members of selected taxa belonging to the family Sphingobacteriaceae using the clustal_x software (Thompson et al., 1997), and this alignment was edited manually.
