Abstract
A Gram-stain-negative, non-motile, rod-shaped bacterial strain, JW-64-1T, capable of degrading methamidophos was isolated from a methamidophos-manufacturing factory in China, and was subjected to a polyphasic taxonomic investigation. Strain JW-64-1T produced circular, smooth, transparent, yellow-colored colonies (1.0–2.0 mm) on LB agar after 2 days incubation. It grew optimally at 25–30°C and pH 7.0 without the presence of NaCl. The G+C content of the total DNA was 63.6 mol%. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain JW-64-1T fell within the cluster comprising Luteibacter species. The 16S rRNA gene sequence of strain JW-64-1T was most closely related to Luteibacter rhizovicinus DSM 16549T (98.6%), followed by Luteibacter yeojuensis DSM 17673T (98.4%) and L. anthropi CCUG 25036T (98.2%). The major cellular fatty acids of strain JW-64-1T were iso-C15:0 (24.1%), iso-C17:0 (20.2%) and summed feature 9 comprising iso-C17:1 ω9c and/or C16:0 10-methyl (20.3%). The major isoprenoid quinine was Q-8 (98%), and the major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphoaminolipid, aminolipids-1, aminolipids-2, and phospholipids. The values for DNA–DNA relatedness between strain JW-64-1T and the closest phylogenetic relatives of L. rhizovicinus and Luteibacter yeojuensis were 34.8 ± 2.6 and 25.6 ± 3.1%, respectively. On the basis of the phenotypic, chemotaxonomic, DNA–DNA relatedness and phylogenetic analysis based on the 16S rRNA gene sequences, strain JW-64-1T represents a novel species of the genus Luteibacter, for which the name Luteibacter jiangsuensis sp. nov. is proposed. The type strain is JW-64-1T (=CGMCC 1.10133T = DSM 22396T).
