The major cellular fatty acids (> 10%) were identified as iso-C_15:0, iso-C_17:0 3-OH and summed features 3 (C_16:1 ω6c and/or C_16:1 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 LAM9153^T 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 LAM9153^T (= ACCC 19960^T = JCM 30847^T).     

<Emphasis Type="Italic">Streptomyces ginkgonis</Emphasis> sp. nov., an endophyte from <Emphasis Type="Italic">Ginkgo biloba</Emphasis>

A novel endophytic actinomycete strain, designated KM-1-2^T, was isolated from seeds of Ginkgo biloba at Yangling, China. A polyphasic approach was used to study the taxonomy of strain KM-1-2^T and it was found to show a range of phylogenetic and chemotaxonomic properties consistent with those of members of the genus Streptomyces. The diamino acid of the cell wall peptidoglycan was identified as LL-diaminopimelic acid. No diagnostic sugars were detected in whole cell hydrolysates. The predominant menaquinones were identified as MK-9(H₆) and MK-9(H₈). The diagnostic phospholipids were found to be phosphatidylethanolamine and phosphatidylcholine. The DNA G + C content of the novel strain was determined to be 72.9 mol%. The predominant cellular fatty acids (> 10.0?%) were identified as iso-C_14?:?0, iso-C_16?:?0, C_16?:?0 and C_17?:?0 cyclo. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that the strain is closely related to Streptomyces carpaticus JCM 6915^T (99.3%), Streptomyces harbinensis DSM 42076^T (98.9%) and Streptomyces cheonanensis JCM 14549^T (98.5%). DNA-DNA hybridizations with these three close relatives gave similarity values of 39.1 ± 1.9, 35.8 ± 2.3, and 47.4 ± 2.7%, respectively, which indicated that strain KM-1-2^T represents a novel species of the genus Streptomyces. This is consistent with the morphological, physiological and chemotaxonomic data. Cumulatively, these data suggest that strain KM-1-2^T represents a novel Streptomyces species, for which the name Streptomyces ginkgonis sp. nov. is proposed, with the type strain KM-1-2^T (= CCTCC AA2016004^T = KCTC 39801^T).
