A novel endophytic actinomycete, designated strain 202201T, was isolated from an Acanthus illicifolius root collected from the mangrove reserve zone in Hainan Province, China. Phylogenetic analysis based on 16S rRNA gene sequences suggested that strain 202201T fell within the family Micromonosporaceae. The strain formed an extensively branched substrate mycelium, which carried uneven warty-surfaced spores. Cell walls of strain 202201T contained meso-diaminopimelic acid and xylose, mannose, arabinose, ribose and glucose were detected as whole-cell sugars. The acyl type of the cell-wall polysaccharides was glycolyl. The major menaquinones were MK-9(H4), MK-9(H6), MK-9(H8) and MK-10(H4). The polar lipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylinositol mannoside and phosphatidylserine. The major cellular fatty acids were 10-methyl-C17 : 0, iso-C15 : 0, iso-C16 : 0 and C17 : 1ω8c. The DNA G+C content was 72.3 mol%. On the basis of the morphological and chemotaxonomic characteristics, phylogenetic analysis and characteristic patterns of 16S rRNA gene signature nucleotides, strain 202201T ( = CGMCC 4.5597T  = DSM 45430T) represents a novel species of a new genus within the family Micromonosporaceae, for which the name Jishengella endophytica gen. nov., sp. nov. is proposed.

Emended Description

A Gram-stain-positive actinobacterial strain, Miq-4T, was isolated from soil around Meighan wetland in the centre of Iran. Strain Miq-4T was strictly aerobic, catalase- and oxidase-positive. The isolate grew in the presence of 3–15 % (w/v) NaCl, at 20–40 °C and pH 6.0–11.0. The optimum NaCl, temperature and pH for growth were 7.0 %, 30 °C and 7.0–8.5, respectively. The cell wall of strain Miq-4T contained meso-diaminopimelic acid as the diamino acid and glucose and ribose as the whole-cell sugars. The polar lipid pattern consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and phosphatidylinositol mannoside. Strain Miq-4T synthesized cellular fatty acids of anteiso- and iso-branched types, including anteiso-C17 : 0, anteiso- C15 : 0 and iso-C16 : 0, and the major respiratory quinone was MK-9(H4). The G+C content of the genomic DNA was 68.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences and characteristic patterns of 16S rRNA gene signature nucleotides revealed that strain Miq-4T belongs to the family Glycomycetaceae and showed the closest phylogenetic similarity with Haloglycomyces albus YIM 92370T (94.1 % 16S rRNA gene sequence similarity). On the basis of phylogenetic analysis and phenotypic and chemotaxonomic characteristics, strain Miq-4T represents a novel species of a new genus in the family Glycomycetaceae, for which the name Salininema proteoliyticum gen. nov., sp. nov. is proposed. The type strain of the type species is Miq-4T ( = IBRC-M 10908T = LMG 28391T). An emended description of the family Glycomycetaceae is also proposed in order to include features of the new genus.

A mesophilic strain, designated A 9500T, was isolated from a soil sample collected from Sobaek Mountain, South Korea, and its taxonomic position was investigated by using a polyphasic approach. The novel strain grew well on different ISP media and no diffusible pigments were produced. The optimum temperature for growth was 32 °C. The aerial mycelium was well developed, but not fragmented. The strain was Gram-positive, non-motile and formed endospores on vegetative and aerial hyphae with a spiny surface. Cell walls of strain A 9500T contained meso-diaminopimelic acid as the diagnostic amino acid, but no characteristic sugars or other amino acids were found (chemotype-III). The major menaquinone was MK-9(H4) and the minor menaquinone was MK-10(H4) and they were detected at a ratio of 7 : 3. Phosphatidylethanolamine was the diagnostic phospholipid. The G+C content of the genomic DNA was 39.4 mol%. The major fatty acids were anteiso-C15 : 0 (43.34 %), iso-C16 : 0 (14.23 %) and C16 : 0 (7.90 %), a composition that differed from members of related genera of the family Thermoactinomycetaceae. The novel strain formed a distinct clade in a phylogenetic tree based on 16S rRNA gene sequences. On the basis of a range of phenotypic and genotypic data and on 16S rRNA gene sequence similarities (88.35–90.38 %), it is suggested that strain A 9500T represents a novel species in a new genus with the name Shimazuella kribbensis gen. nov., sp. nov.

A mesophilic, aerobic, Gram-stain-positive, filamentous bacterial strain, designated ZYf1a3T, was isolated from rice paddy soil in Japan. This strain grew on a solid medium with formation of substrate mycelium; endospores were produced singly along the mycelium. Formation of aerial mycelium was not observed on any of the media tested. This strain produced a characteristic saffron yellow soluble pigment. Cloned 16S rRNA gene sequences of strain ZYf1a3T yielded three different copies (similarity between the three sequences: 99.8–99.9 %). One of these sequences had one base deletion. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain ZYf1a3T belongs to an independent phylogenetic lineage of the family Thermoactinomycetaceae. The cell wall of strain ZYf1a3T contained meso-diaminopimelic acid, alanine and glutamic acid, but no characteristic sugars. It contained menaquinone 7 as the sole menaquinone. The major cellular fatty acids were iso-C15 : 0 and anteiso-C15 : 0.The major polar lipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phosphatidyl-N-methylethanolamine and unidentified aminophospholipids. The DNA G+C content was 42.5 mol%. From phylogenetic analysis based on 16S rRNA gene sequences and phenotypic characteristics, this strain is considered to represent a novel species in a new genus, for which the name Croceifilum oryzae gen. nov., sp. nov. is proposed. The type strain of Croceifilum oryzae is ZYf1a3T ( = JCM 30426T = CCUG 66446T = DSM 46876T).

A Gram-reaction-positive, motile, coccus-shaped actinobacterium, designated strain T2A-S27T, was isolated from a roof tile in Oporto (Portugal) and studied using a polyphasic approach. The 16S rRNA gene sequence of the novel isolate showed high similarity to that of Kineococcus marinus KST3-3T (97.8 % sequence similarity). Strain T2A-S27T showed lower 16S rRNA gene sequence similarities with other members of the genus Kineococcus and members of the family Kineosporiaceae (<94 %). A phylogenetic tree, based on 16S rRNA gene sequences, showed that strain T2A-S27T formed a coherent clade with the type strain of K. marinus and Quadrisphaera granulorum. The isolate was characterized by the presence of meso-diaminopimelic acid in the cell-wall peptidoglycan, MK-9(H2) as the predominant menaquinone and a polar lipid profile consisting of diphosphatidylglycerol and phosphatidylglycerol. The fatty acid profile was dominated by anteiso-C15 : 0. The DNA G+C content was 76.9 mol%. The low level of DNA–DNA relatedness to K. marinus (46–47 %) and the results of the chemotaxonomic and physiological studies clearly distinguished strain T2A-S27T from recognized species of the genus Kineococcus. On the basis of its phylogenetic position and phenotypic traits, strain T2A-S27T ( = LMG 24148T  = CECT 7306T  = DSM 23768T) represents a novel species of a new genus in the family Kineosporiaceae, for which the name Pseudokineococcus lusitanus gen. nov., sp. nov. is proposed. The misclassified species K. marinus is transferred to the new genus as Pseudokineococcus marinus comb. nov. The type strain of Pseudokineococcus marinus is KST3-3T ( = KCCM 42250T  = NRRL B-24439T).

The taxonomic position of Sphingobacterium antarcticum has been revised by means of 16S rRNA gene sequences, DNA–DNA hybridization, and phenotypic and chemotaxonomic characteristics. All data previously reported, as well as the results of the present phylogenetic analysis, support that Sphingobacterium antarcticum is clearly a member of the genus Pedobacter , also affiliated with the family Sphingobacteriaceae . We propose that Sphingobacterium antarcticum (corrig. Shivaji et al. 1992) should be reclassified as Pedobacter antarcticus comb. nov.
