Comparative 16S rRNA gene sequence studies showed a clear affiliation of this bacterium to the Gammaproteobacteria, and it was most closely related to Hydrocarboniphaga effusa ATCC BAA 332^T (94.4%, 16S rRNA gene sequence similarity), Nevskia ramosa DSM 11499^T (94.1%) and Alkanibacter difficilis MN154.3^T (92.0%). Strain Gsoil 142^T was a Gram-negative, strictly aerobic, motile, and rod-shaped bacterium. The G+C content of the genomic DNA was 69.9% and predominant ubiquinone was Q-8. Major fatty acids were summed feature 8 (C_18:1 ω7c and/or ω6c, 36.3%), summed feature 3 (iso-C_15:0 2-OH and/or C_16:1 ω7c, 20.6%) and C_16:0 (17.4%). The major polar lipids detected in strain Gsoil 142^T were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, and an unknown glycolipid. On the basis of polyphasic evidence, it is proposed that strain Gsoil 142^T should be placed in a novel genus and species, for which the name Panacagrimonas perspica gen. nov., sp. nov. is proposed. The type strain is Gsoil 142^T (= KCTC 12982^T = LMG 23239^T).     

<Emphasis Type="Italic">Marinobacterium marisflavi</Emphasis> sp. nov., Isolated from a Costal Seawater

A marine bacterium designated strain IMCC4074^T was isolated from surface seawater collected off Incheon Port, the Yellow Sea, and subjected to a polyphasic taxonomy. The strain was Gram-negative, chemoheterotrophic, slightly halophilic, strictly aerobic, and motile rods. Based on 16S rRNA gene sequence comparisons, the strain was most closely related to Marinobacterium litorale KCTC 12756^T (93.9%) and shared low 16S rRNA gene sequence similarities with members of the genus Marinobacterium (91.8–93.9%) and the genus Neptunomonas (93.4%) in the order Oceanospirillales. Phylogenetic analyses showed that this marine isolate formed an independent phyletic line within the genus Marinobacterium clade. The DNA G+C composition of the strain was 56.0 mol% and the predominant constituents of the cellular fatty acids were C_16:0 (28.0%), C_16:1 ω7c and/or iso-C_15:0 2-OH (19.3%), C_18:1 ω7c (17.8%), and C_17:1 cyclo (12.5%), which differentiated the strain from other Marinobacterium species. Based on the taxonomic data collected in this study, only a distant relationship could be found between strain IMCC4074^T and other members of the genus Marinobacterium, thus the strain represents a novel species of the genus Marinobacterium, for which the name Marinobacterium marisflavi sp. nov. is proposed. The type strain of Marinobacterium marisflavi is IMCC4074^T (= KCTC 12757^T = LMG 23873^T). The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain IMCC4074^T is EF468717.

<Emphasis Type="Italic">Amycolatopsis endophytica</Emphasis> sp. nov., a novel endophytic actinomycete isolated from oil-seed plant <Emphasis Type="Italic">Jatropha curcas</Emphasis> L.

A novel actinomycete, designated KLBMP 1221^T, was isolated from the surface-sterilized seeds of an oil-seed plant Jatropha curcas L. collected from Sichuan Province, south-west China and was characterized taxonomically by using a polyphasic approach. Phylogenetic analyses based on 16S rRNA gene sequence showed that this strain formed a distinct phyletic line within the radiation of the genus Amycolatopsis. The 16S rRNA gene sequence similarity indicated that strain KLBMP 1221^T was most closely related to Amycolatopsis eurytherma NT202^T (98.9%), Amycolatopsis tucumanensis ABO^T (98.8%), Amycolatopsis thermoflava N1165^T (98.6%) and Amycolatopsis methanolica IMSNU 20055^T (98.5%). Strain KLBMP 1221^T had morphological and chemotaxonomic properties that were consistent with its classification in the genus Amycolatopsis. However, DNA–DNA relatedness data and phenotypic differences clearly distinguished the isolate from its closest relatives. Based on the combined genotypic and phenotypic evidence, it is proposed that strain KLBMP 1221^T be classified as representative of a novel species for which the name Amycolatopsis endophytica sp. nov. is proposed. The type strain is KLBMP 1221^T (= KCTC 19776^T = CCTCC AA 2010003^T).
