ABSTRACT
A novel aerobic bacterium, designated strain LAM9153T, was isolated from a saline soil sample collected from Lingxian County, Shandong Province, China. Cells of strain LAM9153T were observed to be Gram-stain negative, non-motile, non-spore-forming and rod-shaped. The new isolate grew optimally at 30-35 °C, pH 7.0 and 0.5% of NaCl concentration (w/v). According to the phylogenetic analysis based on the 16S rRNA gene sequence, strain LAM9153T shares high similarity with Chitinophaga terrae Gsoil 238T (96.9%) and Chitinophaga niabensis JS 13-10T (95.9%), forming a subcluster with C. terrae Gsoil 238T, Chitinophaga cymbidii R156-2T, C. niabensis JS 13-10T and Chitinophaga soli Gsoil 219T in the phylogenetic tree. The major cellular fatty acids (> 10%) were identified as iso-C150, iso-C170 3-OH and summed features 3 (C161 ω6c and/or C161 ω7c). The predominant respiratory quinone was identified as menaquinone MK-7. The polar lipids consisted of phosphatidylethanolamine, aminophospholipid, three unidentified aminolipids and five unidentified lipids. The genomic DNA G+C content was determined to be 53.2 ± 1.6 mol%. On the basis of phylogenetic, chemotaxonomic and phenotypic data, strain LAM9153T is concluded to represent a novel species of the genus Chitinophaga, for which the name Chitinophaga salinisoli sp. nov. is proposed. The type strain is LAM9153T (= ACCC 19960T = JCM 30847T).
