The combination of phylogenetic analysis, DNA–DNA relatedness values, phenotypic characteristics and chemotaxonomic data supports the proposal that strain JSM 071043^T represents a novel species of the genus Zhihengliuella, for which the name Z. salsuginis sp. nov. is proposed. The type strain is JSM 071043^T (= DSM 21149^T = KCTC 19466^T).     

Kineococcus glutineturens sp. nov., isolated from soil in Yunnan, south-west China

An orange-coloured, non-spore-forming, motile and coccus-shaped actinobacterium, designated YIM 75677^T, was isolated from a soil sample collected from a dry-hot river valley in Dongchuan county, Yunnan Province, south-west China and its taxonomic position was investigated. Growth of strain YIM 75677^T occurred at 12–55 °C, pH 6.0–9.0 and NaCl tolerance up to 2 % (w/v). Cells adhered to agar media and were agglutinated tightly together. The peptidoglycan contained meso-diaminopimelic acid, alanine and glutamic acid. The whole-cell hydrolysates mainly contained glucose, galactose, mannose and ribose. The predominant menaquinone was MK-9 (H₂) and the major fatty acids were anteiso-C_15:0 and iso-C_15:0. Mycolic acids were not present. The DNA G+C content of strain YIM 75677^T was 74.8 mol%. Phylogenetic analyses based on 16S rRNA gene sequence comparisons clearly revealed that strain YIM 75677^T represents a novel member of the genus Kineococcus and is closely related to Kineococcus xinjiangensis S2-20^T (level of similarity, 98.6 %). Meanwhile, the result of DNA–DNA hybridization between strain YIM 75677^T and K. xinjiangensis S2-20^T demonstrated that this isolate represented a different genomic species in the genus Kineococcus. On the basis of phylogenetic, phenotypic and chemotaxonomic characteristics, strain YIM 75677^T represents a novel species of the genus Kineococcus, for which the name Kineococcus glutineturens sp. nov. is proposed. The type strain is YIM 75677^T (=CCTCC AA 209075^T = JCM 18126^T).     

Phycicoccus ochangensis sp. nov., isolated from soil of a potato cultivation field

Two novel, Gram-positive, motile, coccal bacteria, strains L1b-b9^T and B5a-b5, were isolated from a potato cultivation field in Ochang, Korea. These isolates grew at 10–45°C, pH 5.0–10.0, and in the presence of 8% (w/v) NaCl. The diagnostic diamino acid in the cell-wall peptidoglycan was meso-diaminopimelic acid. The major menaquinone was MK-8(H₄) and the main cellular fatty acids were iso-C_14:0, iso-C_15:0, and anteiso-C_15:0. Polar lipids in strain L1b-b9^T consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, and an unknown glyco-amino lipid. The G+C content of genomic DNA was 73.6 mol%. A phylogenetic analysis based on 16S rRNA gene sequences showed that strains L1b-b9^T and B5a-b5 shared 99.36% similarity and formed a robust clade with the type species of the genus Phycicoccus. Strain L1b-b9^T is related most closely to Phycicoccus cremeus V2M29^T (97.52% 16S rRNA gene sequence similarity). On the basis of phylogenetic characteristics, the name Phycicoccus ochangensis sp. nov. is proposed for strain LIb-b9^T (=KCTC 19694^T =JCM 17595^T).
