ABSTRACT
A novel strain, yH16, was isolated on nutrient agar from soil samples collected at KyungHee University, Suwon City, Republic of Korea. Cells of strain yH16(T) were short rods, Gram-negative-staining, motile and non-spore-forming, with a polar flagellum. Biochemical and molecular characterization revealed that this strain was most similar to Pseudogulbenkiania subflava BP-5(T). Further 16S rRNA gene sequencing studies revealed that the new strain clustered with Pseudogulbenkiania subflava BP-5(T) (95.9 % similarity), Paludibacterium yongneupense 5YN8-15(T) (95.2 % similarity), Gulbenkiania mobilis E4FC31-5(T) (94.6 % similarity) and Chromobacterium aquaticum CC-SE-YA-1(T) (93.9 % similarity). The isolate was able to grow at 25-40 °C, 0.3-2 % NaCl and pH 5.5-7. The DNA G+C content was 65.9 ± 1.0 mol%. The predominant fatty acids were summed feature 3 (C(16 : 1)ω7c and/or iso-C(15 : 0) 2-OH) and C(16:0). Ubiquinone 8 was the major respiratory quinone. It was evident from the data obtained that the strain should be classified as a novel species of the genus Pseudogulbenkiania. The name proposed for this taxon is Pseudogulbenkiania gefcensis sp. nov., and the type strain is yH16(T) (=KCCM 90100(T) = JCM 17850(T)).
