| Description |
A novel marine, Gram-negative, rod-shaped bacterium, designated strain N9(T), was isolated from a water sample of the sea shore at Visakhapatnam, Andhra Pradesh (India). Strain N9(T) was found to be positive for oxidase and catalase activities. The fatty acids were found to be dominated by C(16:0), C(18:1) ω7c and summed in feature 3 (C(16:1) ω7c and/or C(16:1) ω6c). Strain N9(T) was determined to contain Q-10 as the major respiratory quinone and phosphatidylethanolamine, phosphatidylglycerol, two aminophospholipids, two phospholipids and four unidentified lipids as polar lipids. The DNA G+C content of the strain N9(T) was found to be 63 mol%. 16S rRNA gene sequence analysis indicated that Rhodobacter sphaeroides, Rhodobacter johrii, Pseudorhodobacter ferrugineus, Rhodobacter azotoformans, Rhodobacter ovatus and Pseudorhodobacter aquimaris were the nearest phylogenetic neighbours, with pair-wise sequence similarities of 95.43, 95.36, 94.24, 95.31, 95.60 and 94.74 %, respectively. Phylogenetic analysis showed that strain N9(T) formed a distinct branch within the family Rhodobacteraceae and clustered with the clade comprising species of the genus Pseudorhodobacter, together with species of the genera Roseicitreum, Roseinatronobacter, Roseibaca and Rhodobaca. Species of the genus Pseudorhodobacter are phylogenetically close with a 16S rRNA gene sequence dissimilarity of 5.9-7.3 % (92.7-94.1 % similarity). Based on the above-mentioned phenotypic characteristics and on phylogenetic inference, strain N9(T) is proposed as a representative of a new genus and a novel species of the family Rhodobacteraceae as Albirhodobacter marinus gen. nov., sp. nov. The type strain of Albirhodobacter marinus is N9 (= MTCC 11277(T) = JCM 17680(T)).
