Freshwater Pond

A novel bacterial strain, designated KMB7T, isolated from a freshwater pond in Taiwan, was characterized using a polyphasic taxonomic approach. Cells were Gram-stain-negative, motile by means of a single polar flagellum, rod-shaped and formed cream colonies. Optimal growth occurred at 25 °C, pH 7, and in the absence of NaCl. Phylogenetic analyses based on 16S rRNA gene sequences and an up-to-date bacterial core gene set (92 protein clusters) indicated that strain KMB7T is affiliated with species in the genus Aquabacterium . The 16S rRNA gene sequence similarity indicated that strain KMB7T is closely related to species within the genus Aquabacterium (95.2–97.6 % sequence similarity) and is most similar to A. fontiphilum CS-6T (97.6 %), followed by A. parvum B6T (97.5 %). The average nucleotide identity and digital DNA–DNA hybridization identity between strain KMB7T and the closely related strains were 74.6–78.0 % and 19.0–21.2 %, respectively. The major fatty acids of strain KMB7T were summed feature 3 (C16 : 1  ω7c and/or C16 : 1  ω6c), C18 : 1  ω7c and C16 : 0. The polar lipid profile consisted of a mixture of phosphatidylethanolamine, phosphatidylglycerol, phosphatidylserine, diphosphatidylglycerol and four unidentified phospholipids. The sole isoprenoid quinone was ubiquinone-8 (Q-8). Genomic DNA G+C content of strain KMB7T was 65.4 %. On the basis of phenotypic and genotypic properties and phylogenetic inference, strain KMB7T should be classified in a novel species of the genus Aquabacterium , for which the name Aquabacterium lacunae sp. nov. is proposed. The type strain is KMB7T (=BCRC 81156T=LMG 30924T=KCTC 62867T).

The Gram-strain-negative, rod-shaped, facultatively anaerobic, non-motile bacterial strain, designated S1-10T, was isolated from marine sediment. Strain S1-10T grew at 4–42 °C (optimally at 30–35 °C), at pH 7.0–10 (optimally at pH 9) and in the presence of 0.5–8 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain S1-10T was related to the genus Aequorivita and had highest 16S rRNA gene sequence similarity to Aequorivita viscosa 8-1bT (97.7%). The predominant cellular fatty acids were iso-C15 : 0 and anteiso-C15 : 0. The main respiratory quinone was menaquinone 6 (MK-6). The genomic DNA G+C content of strain S1-10T was 34.6 mol%. The polar lipid profile of strain S1-10T contained phosphatidylethanolamine, two aminolipids, two glycolipids, one phosphoglycolipid and three unidentified polar lipids. In addition, the maximum values of in silico DNA–DNA hybridization (isDDH) and average nucleotide identity (ANI) between strain S1-10T and A. viscosa CGMCC 1.11023T were 15.4 and 75.7 %, respectively. Combined data from phenotypic, phylogenetic, isDDH and ANI analyses demonstrated that strain S1-10T is the representative of a novel species of the genus Aequorivita , for which we propose the name Aequorivita sinensis sp. nov. (type strain S1-10T=CGMCC 1.12579T=JCM 19789T). We also propose that Vitellibacter todarodis and Vitellibacter aquimaris should be transferred into genus Aequorivita and be named Aequorivita todarodis comb. nov. and Aequorivita aquimaris comb. nov., respectively. The type strain of Aequorivita todarodis comb. nov. is MYP2-2T (= KCTC 62141T= NBRC 113025T) and the type strain of Aequorivita aquimaris comb. nov. is D-24T (=KCTC 42708T=DSM 101732T).
