Aurantivirga profunda gen. nov., sp. nov., isolated from deep-seawater, a novel member of the family Flavobacteriaceae , was isolated from deep seawater in the Pacific Ocean. 16S rRNA gene sequence analysis revealed that the strain could be affiliated with the family Flavobacteriaceae of the phylum Bacteroidetes and shared less than 94.6 % similarity with other species of the family with validly published names. The phenotypic characteristics of this novel isolate, such as growth properties and enzyme activities, could be differentiated from those of other species. The strain was non-motile, oxidase-positive and catalase-negative. The G+C content of the genomic DNA was determined to be 34.8 mol% and menaquinone-6 (MK-6) was the predominant isoprenoid quinone. The predominant fatty acids were iso-C 15 : 0 , iso-C 15 : 1 G, iso-C 16 : 0 3-OH, iso-C 17 : 0 3-OH and iso-C 15 : 0 3-OH. The major polar lipids comprised phosphatidylethanolamine, three unknown aminolipids and three unknown lipids. On the basis of the taxonomic data collected in this study, it was concluded that strain SAORIC-234 T represents a novel genus and species in the family Flavobacteriaceae, for which the name Aurantivirga profunda gen. nov., sp. nov. is proposed. The type strain of the type species, Aurantivirga profunda sp. nov., is SAORIC-234

A Gram-staining-negative, motile by flagella, non-pigmented, poly-b-hydroxybutyrate-producing, strictly aerobic and sphere-shaped bacterium, IMCC3490 T , was isolated from a coastal seawater sample from the Antarctic Peninsula. Optimal growth of strain IMCC3490T was observed at 20 6C, pH 8.0 and in the presence of 2 % (w/v) NaCl. Phylogenetic analysis using 16S rRNA gene sequences indicated that strain IMCC3490 T belonged to the genus Granulosicoccus in the family Granulosicoccaceae. The strain was closely related to Granulosicoccus antarcticus IMCC3135 T (98.8 % 16S rRNA gene sequence similarity) and Granulosicoccus coccoides Z 271 T (98.5 %). The DNA-DNA relatedness values between IMCC3490 T and type strains of the two species of the genus were far lower than 70 %, which indicated strain IMCC3490 T is a novel genomic species of the genus Granulosicoccus. The major fatty acids of strain IMCC3490 T were summed feature 8 (C 18 : 1 v7c and/or C 18 : 1 v6c) and summed feature 3 (C 16 : 1 v7c and/or C 16 : 1 v6c). The isoprenoid quinone detected was ubiquinone-8 (Q-8) and predominant polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The DNA G+C content was 61.0 mol%. On the basis of phylogenetic analyses, DNA-DNA relatedness values and phenotypic data, it is suggested that strain IMCC3490 T represents a novel species of the genus Granulosicoccus, for which the name Granulosicoccus marinus sp. nov. is proposed.
