Abstract

A Gram-negative, strictly aerobic, yellow–orange-pigmented, motile, short rod-shaped, catalase-positive, oxidase-negative bacterium, strain MYL-8, was isolated from wastewater of the Jin Tai Chemical Factory in Hefei, China. Strain MYL-8 grew optimally at 30 °C, in the absence of NaCl and at pH 7. Menaquinone 6 (MK-6) was the sole respiratory quinone and the major fatty acids were iso-C, iso-C G, iso-C 3-OH and summed feature 3 (Cω7 and/or iso-C 2-OH). The polar lipid profile was composed predominantly of unidentified polar lipids and aminolipids. Minor amounts of phosphatidylethanolamine and unidentified phospholipids were also detectable. The DNA G+C content of strain MYL-8 was 43.5 mol%. The 16S rRNA gene sequence of strain MYL-8 showed the highest similarity to that of RW 262 (97.03 %), followed by Haldis-1-1 (92.05 %), UST040201-001 (91.43 %) and JCM 15141 (90.61 %). DNA–DNA relatedness between strain MYL-8 and RW 262 was 21.35±0.90 %. On the basis of phenotypic, chemotaxonomic, genomic and phylogenetic data, strain MYL-8 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is MYL-8 ( = KACC 16597 = CCTCC AB 2013168).
