A Gram-negative, aerobic, non-motile, rod-shaped bacterium, designated MS1-4T, was isolated from mangrove sediment of the Jiulong River Estuary, Fujian Province, China. The isolate formed yellow colonies on ZB 2216E agar. Optimal growth was observed at pH 6.0, at 34 oC and in the presence of 4 % (w/v) NaCl. Strain MS1-4T shared highest 16S rRNA gene sequence similarity of 97.7 % with Altererythrobacter mangrovi C9-11T, followed by Altererythrobacter ishigakiensis JPCCMB0017T (97.2 %). Phylogenetic analysis indicated that strain MS1-4T formed a clade with A. mangrovi C9-11T within the genus Altererythrobacter. The main cellular fatty acid was summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c) and the sole respiratory quinone was ubiquinone Q-10. The main polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and glycolipids. The G+C content of the DNA was 60.4 mol%. Based on data from this polyphasic characterization, strain MS1 4T should be classified as representing a novel species in the genus Altererythrobacter, for which the name Altererythrobacter flavus sp. nov. is proposed. The type strain is MS1-4T (=MCCC 1K02683T=NBRC 112977T).
Figure 1. Neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showing the relationships of strain MS1-4T and representatives of closely related taxa. Bootstrap values (1000 replications, >50 %) are shown at branch nodes. The filled circles indicate branches that were also formed by using maximum-likelihood and minimum-evolution methods. Caulobacter vibrioides CB51T was used as the outgroup. Bar, 0.02 substitutions per nucleotide position.
