A Gram-stain-negative, rod-shaped bacterial strain, JN53T, was isolated from the surfaces of weathered rock (potassic trachyte) from Nanjing, Jiangsu Province, PR China. Strain JN53T grew optimally at 30 °C, pH 7.0. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain JN53T belonged to the genus Chitinophaga in the family Chitinophagaceae . It was most closely related to Chitinophaga terrae KP01T (97.3 % 16S rRNA gene sequence similarity), Chitinophaga eiseniae YC6729T (96.3 %). Strain JN53T contained MK-7 as the major menaquinone and homospermidine as the major polyamine. The main fatty acids of strain JN53T were iso-C15 : 0, C16 : 1ω5c, C16 : 1ω7c and/or C16 : 1ω6c (summed feature 3), iso-C17 : 0 3-OH, C16 : 0, iso-C15 : 0 3-OH and C16 : 0 3-OH. The polar lipid profile contained phosphatidylethanolamine, unknown aminolipids and unknown lipids. The total DNA G+C content of strain JN53T was 49.7 mol%. The low level of DNA–DNA relatedness to other species of the genus Chitinophaga and the many phenotypic properties that distinguished strain JN53T from recognized species of this genus demonstrated that isolate JN53T should be classified as representing a novel species of the genus Chitinophaga , for which the name Chitinophaga jiangningensis sp. nov. is proposed. The type strain is JN53T ( = CCTCC AB 2013166T = JCM 19354T).

A Gram-stain-negative, aerobic, non-motile and rod-shaped bacterial strain, designated WT-MW11T, was isolated from wood falls on the coast of Wando, an island of South Korea, and its taxonomic position was investigated by using a polyphasic approach. Strain WT-MW11T grew optimally at pH 7.0–8.0, at 25 °C and in the presence of 2.0–3.0 % (w/v) NaCl. Bacteriochlorophyll a was not produced. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain WT-MW11T clustered with Pseudorhodobacter ferrugineus IAM 12616T and Pseudorhodobacter aquimaris HDW-19T, with which it exhibited 16S rRNA gene sequence similarity values of 97.9 and 95.5 %, respectively. Strain WT-MW11T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid. The polar lipid profile of strain WT-MW11T was similar to those of P. ferrugineus JCM 20687T and P. aquimaris HDW-19T. The DNA G+C content of strain WT-MW11T was 61.6 mol% and its mean DNA–DNA relatedness value with P. ferrugineus JCM 20687T was 12.3 %. The phylogenetic and genetic distinctiveness and differential phenotypic properties revealed that strain WT-MW11T was distinguishable from the two recognized species of the genus Pseudorhodobacter . On the basis of the data presented, strain WT-MW11T is considered to represent a novel species of the genus Pseudorhodobacter , for which the name Pseudorhodobacter wandonensis sp. nov. is proposed. The type strain is WT-MW11T ( = KCTC 23672T = CCUG 61506T). The description of the genus Pseudorhodobacter is emended.

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).

A Gram-negative, non-motile, non-spore-forming bacterial strain, PR1T, was isolated from a mud core sample containing colonial choanoflagellates near Hog Island, Virginia, USA. Strain PR1T grew optimally at 30 °C and with 3 % (w/v) NaCl. Strain PR1T contained MK-7 as the major menaquinone as well as carotenoids but lacked pigments of the flexirubin-type. The predominant fatty acids were iso-C15 : 0 (29.4 %), iso-C17 : 1ω9c (18.5 %) and summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c; 11.3 %). The major polar lipids detected in strain PR1T were phosphatidylethanolamine, an unknown phospholipid, an aminophospholipid, an aminolipid and two lipids of unknown character. The DNA G+C content was 38.7 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain PR1T fell within the cluster comprising the genus Algoriphagus and was most closely related to Algoriphagus halophilus JC 2051T (95.4 % sequence similarity) and Algoriphagus lutimaris S1-3T (95.3 % sequence similarity). The 16S rRNA gene sequence similarity between strain PR1T and the type strains of other species of the genus Algoriphagus were in the range 91–95 %. Differential phenotypic properties and phylogenetic and genetic distinctiveness of strain PR1T demonstrated that this strain was distinct from other members of the genus Algoriphagus , including its closest relative, A. halophilus . Based on phenotypic, chemotaxonomic, phylogenetic and genomic data, strain PR1T should be placed in the genus Algoriphagus as a representative of a novel species, for which the name Algoriphagus machipongonensis sp. nov. is proposed. The type strain is PR1T ( = ATCC BAA-2233T  = DSM 24695T).
