Ascidiimonas aurantiaca gen. nov., sp. nov., a member of Flavobacteriaceae isolated from a sea squirt

Paramesonia marina gen. nov., sp. nov., isolated from deep-sea water of the Indian Ocean

A taxonomic study was carried out of strain K7^T, which was isolated from deep-sea water collected from the Indian Ocean. The bacterium was Gram-stain-negative, aerobic, oxidase-negative, catalase-positive, rod-shaped and non-motile. Growth was observed at salinities of 0.5-10 % (optimum, 3 %), at a pH range of pH 6.0-10.0 (optimum, pH 7.0) and at temperatures of 10-40 °C (optimum, 28 °C). Results of phylogenetic analysis based on 16S rRNA gene sequences indicated that strain K7^T belonged to the family Flavobacteriaceae, with the high sequence similarities to the genera Mesonia (92.2 %-94.4 %), Salinimicrobium (91.9 %-93.2 %), Salegentibacter (92.1 %-92.6 %), Leeuwenhoekiella (92.1 %-92.3 %), Gramella (91.9 %-92.1 %) and Zunongwangia (91.8 %-92.1 %). The principal fatty acids were iso-C_15 : 0 (28.4 %), iso-C_15 : 1G (14.2 %), summed feature 9 (iso-C_17 : 1  ω9c and/or C_16 : 0 10-methyl; 11.6 %), iso-C_17 : 0 3-OH (10.0 %) and summed feature 3 (C_16 : 1 ω7c and/or C_16 : 1 ω6c; 9.6 %). The G+C content of the chromosomal DNA was 35.8 mol%. The respiratory quinone was determined to be MK-6 (100 %). Phosphatidylethanolamine, two unidentified aminolipids, two unidentified phospholipid and four unidentified lipids were detected. The combined genotypic and phenotypic data show that strain K7^T represents a novel species of a novel genus, for which the name Paramesonia marina gen. nov., sp. nov. is proposed, with the type strain K7^T (=MCCC 1A01093^T=KCTC 52325^T).

List of new names and new combinations previously effectively, but not validly, published

The purpose of this announcement is to effect the valid publication of the following effectively published new names and new combinations under the procedure described in the Bacteriological Code (1990 Revision). Authors and other individuals wishing to have new names and/or combinations included in future lists should send an electronic copy of the published paper to the IJSEM Editorial Office for confirmation that all of the other requirements for valid publication have been met. It is also a requirement of IJSEM and the ICSP that authors of new species, new subspecies and new combinations provide evidence that types are deposited in two recognized culture collections in two different countries. It should be noted that the date of valid publication of these new names and combinations is the date of publication of this list, not the date of the original publication of the names and combinations. The authors of the new names and combinations are as given below. Inclusion of a name on these lists validates the publication of the name and thereby makes it available in the nomenclature of prokaryotes. The inclusion of a name on this list is not to be construed as taxonomic acceptance of the taxon to which the name is applied. Indeed, some of these names may, in time, be shown to be synonyms, or the organisms may be transferred to another genus, thus necessitating the creation of a new combination.
