TL;DR: It is proposed that this slow-growing, strictly aerobic, Gram-negative, coccus bacterial strain isolated from sea-floor sediment collected from the Red Sea, Saudi Arabia, represents a novel species of a new genus in the family Rhodobacteraceae, for which the name of Profundibacterium mesophilum gen. nov., sp.
Abstract: A slow-growing, strictly aerobic, Gram-negative, coccus bacterial strain, designated KAUST100406-0324(T), was isolated from sea-floor sediment collected from the Red Sea, Saudi Arabia. The catalase- and oxidase-positive strain was non-sporulating and only slightly halophilic. Optimum growth occurred at 20-25 °C and at pH values ranging from 7.0 to 8.0. The major cellular fatty acids of the strain were unsaturated C18 : 1ω6c and/or C18 : 1ω7c, C18 : 1ω7c 11-methyl and C16 : 1ω7c and/or C16 : 1ω6c. The major polar lipids were phosphatidylglycerol, phosphatidylethanolamine and two unidentified phospholipids. Ubiquinone 10 was the predominant lipoquinone. The DNA G+C content of strain KAUST100406-0324(T) was 64.0 mol%. Phylogenetic analysis of 16S rRNA gene sequences revealed that the novel strain belonged to the family Rhodobacteraceae of the class Alphaproteobacteria but formed a distinct evolutionary lineage from other bacterial species with validly published names. The 16S rRNA gene sequence of the novel strain was distantly related, but formed a monophyletic cluster with, those of bacteria from two moderately halophilic genera, Hwanghaeicola and Maribius. The similarity of the sequence between the novel strain KAUST100406-0324(T) and the type strains Hwanghaeicola aestuarii Y26(T) (accession number FJ230842), Maribius pelagius B5-6(T) (DQ514326) and Maribius salinus CL-SP27(T) (AY906863) were 94.5 %, 95.2 % and 95.3 %, respectively. Based on the physiological, phylogenetic and chemotaxonomic characteristics presented in this study, we propose that this strain represents a novel species of a new genus in the family Rhodobacteraceae, for which the name of Profundibacterium mesophilum gen. nov., sp. nov. was proposed, with KAUST100406-0324(T) ( = JCM 17872(T) = NRRL B-59665(T)) as the type strain.

TL;DR: A novel marine Gram-negative bacterium, isolated from a tidal mudflat sample collected at Dongmak seashore on Gangwha Island, Republic of Korea and its taxonomic position was determined through a polyphasic investigation, represents a novel species of the genus Maribius.
Abstract: A novel marine Gram-negative bacterium, designated strain GH1-23T, was isolated from a tidal mudflat sample collected at Dongmak seashore on Gangwha Island, Republic of Korea and its taxonomic position was determined through a polyphasic investigation. The bacterium was strictly aerobic, chemoheterotrophic, catalase- and oxidase-positive, consisted of non-motile rods and grew optimally at 30 °C, pH 7 and 1 % NaCl. The predominant cellular fatty acids were C18 : 1
ω7c and cyclo-C19 : 0
ω8c. The major isoprenoid quinone was Q-10. The major polar lipids were phosphatidylglycerol, a phosphoglycolipid and an aminolipid. Comparative 16S rRNA gene sequence analysis revealed that the isolate was closely related to members of the genus
Maribius
. The highest 16S rRNA gene sequence similarity was found to be 97.5 % to
Maribius salinus
followed by 97.4 % to
Maribius pelagius
; levels of 16S rRNA gene sequence similarity between the novel strain and other representatives of family
Rhodobacteraceae
were <95.5 %. The DNA G+C content was 66.7 mol % and DNA–DNA relatedness values with the type strains of species of the genus
Maribius
were 33–39 %. Based on combined data from a polyphasic investigation, strain GH1-23T (=KCTC 52957T=DSM 104950T) represents a novel species of the genus

TL;DR: This is the first report of a full genome within the genus Maribius, and interestingly, reveals the presence of genes involved in quorum sensing in this alphaproteobacterium.
Abstract: Maribius sp. strain MOLA401 is an alphaproteobacterium isolated from a coral reef lagoon located in New Caledonia, France. We report the genome sequence and its annotation which, interestingly, reveals the presence of genes involved in quorum sensing. This is the first report of a full genome within the genus Maribius.
