Abstract

An extracellular polysaccharide-producing bacterium, strain SCK, was isolated from a soil sample taken from Kameino, Fujisawa, Japan. The isolate was Gram-negative and cells were non-motile, irregular-shaped rods that grew optimally at 25 °C and grew between pH 5 and 8. Strain SCK contained MK-7 as the major isoprenoid quinone, iso-C and C 7 and/or iso-C 2-OH as the major fatty acids and sphingolipids, with d-17 : 0 as the main dihydrosphingosine. Flexirubin-type pigments were also present. The DNA G+C content was 43.7 mol%. On the basis of 16S rRNA gene sequence analysis, strain SCK was shown to belong to the genus . The 16S rRNA gene sequence similarity between strain SCK and the two type strains of was 93 %. The results of physiological and biochemical tests allowed phenotypic differentiation of the strain from published species. Therefore, strain SCK represents a novel species, for which the name sp. nov. is proposed. The type strain is SCK (=NBRC 102645 =KCTC 22227).
