Abstract

The taxonomic position of a novel Gram-negative strain, designated SY1, isolated from a farm-soil sample obtained from Jiangsu Province, PR China, was characterized by using a polyphasic approach. The cells were non-motile, non-spore-forming rods. The organism grew optimally at 30–37 °C and at pH 6.0–8.0. Based on 16S rRNA gene sequence analysis, strain SY1 is a member of the genus ; JCM 21156 was the nearest relative (98.5 % sequence similarity). The predominant fatty acids of strain SY1 were iso-C (32.9 %), C (10.9 %) and summed feature 3 (iso-C 2-OH and/or C 7; 24.1 %). The DNA G+C content was 38.5 mol%. The low level of DNA–DNA relatedness (2.2 %) to JCM 21156 in combination with differential morphological and biochemical properties demonstrated that strain SY1 (=KCTC 22131=CGMCC 1.6855) should be classified as representing a novel species of the genus for which the name sp. nov. is proposed.
