“…Some species of this genus such as Citricoccus nitrophenolicus use aromatic compounds as the only source of carbon and energy [44], and C. nitrophenolicus may show lipolytic activity at low temperatures [45]. The genus Altererythrobacter , belonging to the phylum Proteobacteria , has been isolated from various marine and terrestrial environments such as deep-sea water [46], tidal flats [47], marine sediments [48], forests, desert soil [49, 50], hot springs [51], and the air [52]. The genus Fictibacillus , belonging to the phylum Firmicutes , has been previously isolated from different environments, including hot springs [53], industrial wastes [54], metal ores [55], and marine sediments [56].…”

Over 1,000 compounds, including ecteinascidin-743 and didemnin B, have been isolated from ascidians, with most having bioactive properties such as antimicrobial, antitumor, and enzyme-inhibiting activities. In recent years, direct and indirect evidence has shown that some bioactive compounds isolated from ascidians are not produced by ascidians themselves but by their symbiotic microorganisms. Isolated culturable bacteria associated with ascidians and investigating their potential bioactivity are an important approach for discovering novel compounds. In this study, a total of 269 bacteria were isolated from the ascidian Styela clava collected from the coast of Weihai in the north of the Yellow Sea, China. Phylogenetic relationships among 183 isolates were determined using their 16S rRNA gene sequences. Isolates were tested for antimicrobial activity against seven indicator strains, and an antiproliferative activity assay was performed to test for inhibition of human hepatocellular carcinoma Bel 7402 and human cervical carcinoma HeLa cell proliferation. Our results showed that the isolates belonged to 26 genera from 18 families in four phyla (Firmicutes, Actinobacteria, Proteobacteria, and Bacteroidetes). Bacillus and Streptomyces were the most dominant genera; 146 strains had potent antimicrobial activities and inhibited at least one of the indicator strains. Crude extracts from 29 strains showed antiproliferative activity against Bel 7402 cells with IC50 values below 500 μg·mL−1, and 53 strains showed antiproliferative activity against HeLa cells, with IC50 values less than 500 μg·mL−1. Our results suggest that culturable bacteria associated with the ascidian Styela clava may be a promising source of novel bioactive compounds.

“…Its description has been emended mainly based on oxidase activity, NaCl requirement and major polar lipids by Xue et al [3] and the DNA G+C content of 54.5-67.5 mol% by Xue et al [4]. At the time of writing, the names of 36 species belonging to the genus Altererythrobacter have been validly published, and these species were isolated from various habitats including a tidal flat [5], seawater [6,7], water of an estuary [8], wetland freshwater [9], the junction between the ocean and a freshwater spring [10], water of an estuary bank [11], hot spring [12], sediments [1,[13][14][15][16], soils [3,[17][18][19][20], wild rice [21], mudstone core [22], air [4], sea urchin [23], and a saltmarsh plant [24]. Members of the genus Altererythrobacter are Gram-stain-negative, coccoid to rod-shaped, have yellow to orange-red colony colours on plates, lack bacteriochlorophyll a and contain Q-10 as the predominant respiratory quinone.…”

An aerobic, motile, Gram-stain-negative bacterium, designated strain NS1 T , was isolated from interfacial sediment from Taihu Lake, China. The strain formed yellow colonies on R2A medium. Cells were ovoid to rod-shaped and non-sporeforming. Growth occurred at 15-40 C (optimum, 28 C), at pH 5.0-10.5 (optimum, 6.5-7.5) and in the presence of 0-1 % (w/v) NaCl (optimum, 0 %). Phylogenetic trees based on 16S rRNA gene sequences showed that strain NS1 T represented a member of the genus Altererythrobacter and had the highest sequence similarity to Altererythrobacter troitsensis CCTCC AB 2015180 T (97.1 %). The average nucleotide identity value between strain NS1 T and the closest related strain based on their genomes was 78.6 %. The predominant ubiquinone was Q-10. The major fatty acids were summed feature 8 (C 18 : 1 !7c and/ or C 18 : 1 !6c), summed feature 3 (C 16 : 1 !7c and/or C 16 : 1 !6c) and C 16 : 0. The polar lipids comprised diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, an unidentified phospholipid, an unidentified glycolipid and six unidentified lipids. The genomic DNA G+C content was 66.6 mol%. On the basis of phenotypic and genotypic characteristics, strain NS1 T represents a novel species of the genus Altererythrobacter, for which the name Altererythrobacter amylolyticus sp. nov. is proposed. The type strain is NS1 T (=CGMCC 1.13679 T =NBRC 113553 T).

A novel salt-tolerant alpha-proteobacterium, designated SALINAS58T, was isolated from Santa Engracia hypersaline spring water in the Añana Salt Valley, Álava, Spain. The isolate was Gram-negative, aerobic, non-motile, catalase-positive, oxidase-negative, rod-shaped and formed orange colonies on marine agar. Optimal growth was observed at pH 6.0–6.5, at 30 °C and in the presence of 1% (w/v) NaCl. The main cellular fatty acids (>20%) were summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c) and summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c). The major respiratory quinone was ubiquinone Q-10 and the major polar lipids detected were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidilglycerol, four unidentified glycolipids and one unidentified phospholipid. Strain SALINAS58T had the highest 16S rRNA gene sequence similarity to Altererythrobacter marensis MSW-14T (96.6%), Altererythrobacter aquaemixtae JSSK-8T (96.5%) and Pontixanthobacter luteolus SW-109T (96.5%) followed by Altererythrobacter atlanticus 26DY36T (96.4%). Results of the phylogenetic analysis, based on 16S rRNA gene sequences, and phylogenetic approaches based on whole genome nucleotide differences, showed that strain SALINAS58T could be distinguished from recognized species of the genus Altererythrobacter . The genomic DNA G+C content was 61.4 mol%. Digital DNA–DNA hybridization, average nucleotide identity and average aminoacid identity values between the genome of strain SALINAS58T and A. marensis MSW-14T were 18.4, 73.1 and 68.1%, respectively. Based on data from this polyphasic characterization, strain SALINAS58T (=CECT 30029T=LMG 31726T) is considered to be classified as representing a novel species in the genus Altererythrobacter , for which the name Altererythrobacter muriae sp. nov. is proposed.
