Carmen and Arahal, David R. and Pujalte, María J.,, 62, 2858-2864 (2012), doi = https://doi.org/10.1099/ijs.0.038026-0, publicationName = Microbiology Society, issn = 1466-5026, abstract= Strain R46T, a marine alphaproteobacterium, was isolated from Mediterranean seawater at Malvarrosa beach, Valencia, Spain. It is an aerobic chemo-organotrophic, mesophilic and slightly halophilic organism, with complex ionic requirements. Phylogenetic analyses based on the 16S rRNA and gyrB gene sequences showed that strain R46T formed a separate branch within the family Rhodobacteraceae , bearing similarities below 94.7 and 80.3 %, respectively, to any other recognized species. It contained Q10 as the predominant isoprenoid quinone and C18 : 1ω7c/C18 : 1ω6c as the major cellular fatty acid. Phosphatidylglycerol was the only identified polar lipid, although other lipids were also detected. The DNA G+C content of the genomic DNA was 61.3 mol%. On the basis of extensive phenotypic and phylogenetic comparative analysis, it is concluded that the strain represents a novel genus and species, for which the name Actibacterium mucosum gen. nov., sp. nov. is proposed. The type strain of the type species is Actibacterium mucosum R46T ( = CECT 7668T = KCTC 23349T)., language=, type=
