Three strains of Gram-negative, aerobic, neutrophilic and halophilic bacteria were isolated from samples of a salt lake on the Qinghai-Tibet Plateau and a subterranean saline well in the Si-Chuan Basin of China. These isolates, designated AJ275(T), AJ282(T) and ZG16(T), were investigated using a polyphasic approach. Based on 16S rRNA gene sequence analysis,(More)
A Gram-negative, neutrophilic and rod-shaped bacterium, strain ZH17(T), was isolated from a marine sediment of the East China Sea and subjected to a polyphasic taxonomic characterization. The isolate grew in the presence of 0-7.5 % (w/v) NaCl and at pH 6.5-9.0; optimum growth was observed with 0.5-3.0 % (w/v) NaCl and at pH 7.5. Chemotaxonomic analysis(More)
Two halophilic archaeal strains TBN4T and TBN5 were isolated from Taibei marine solar saltern in Jiangsu, China. Both strains showed light red-pigmented colonies and their cells were rod, motile and Gram-stain-negative. They were able to grow at 25–50°C (optimum 37°C), at 1.4–4.3 M NaCl (optimum 2.1 M NaCl), at 0–1.0 M MgCl2 (optimum 0.005 M MgCl2) and at(More)
Two extremely halophilic archaea, strains RO5-2(T) and RO5-14, were isolated from Rudong marine solar saltern in Jiangsu, China. Cells of the two strains were pleomorphic, motile and stained Gram-negative. Colonies were red-pigmented. Strains RO5-2(T) and RO5-14 were able to grow at 20-50 degrees C (optimum 37 degrees C), at 2.6-4.8 M NaCl (optimum 3.4-3.9(More)
Two extremely halophilic archaea, strains RO1-28(T) and RO1-22, were isolated from a marine solar saltern in Jiangsu, China. Both strains required at least 0.05 M Mg(2+) and 1.7 M NaCl for growth. They were able to grow over a pH range of 6.0-8.5 and a temperature range of 25-55 degrees C, with optimal pH of 7.0 and optimal temperature of 37-40 degrees C.(More)
Two extremely halophilic archaeal strains, designated TNN44(T) and TNN58(T), were isolated from Tainan marine solar saltern near Lianyungang city, Jiangsu province, China. Cells of the two strains were pleomorphic and Gram-stain-negative; colonies were red-pigmented. Strains TNN44(T) and TNN58(T) were able to grow at 20-50 °C (optimum 37 °C for both), in(More)
A novel extremely halophilic strain, isolated from Aibi salt lake, Xin-Jiang, China, was subjected to polyphasic taxonomic characterization. This strain, designated AB14T, is neutrophilic, motile and requires at least 10 % (w/v) NaCl for growth. Strain AB14T grows at 24-58 degrees C, with optimal growth at 42-45 degrees C. Mg2+ is not required, but growth(More)
A Gram-negative, aerobic, neutrophilic, coccoid bacterium, strain E4A9T, was isolated from a deep-sea sediment sample collected from the East Pacific polymetallic nodule region. 16S rRNA gene sequence analysis showed that the isolate was related to the type strain of Altererythrobacter epoxidivorans (96.0% sequence similarity). Lower 16S rRNA gene sequence(More)
Three strains of Gram-negative, aerobic, neutrophilic, extremely halophilic archaea, designated ZJ206(T), ZJ203 and ZJ204, were isolated from a solar saltern in Zhe-Jiang Province, China. Phenotypically and on the basis of 16S rRNA gene sequences, the strains were very similar. Comparative 16S rRNA gene analysis revealed 96.4-97.4 % sequence similarity to(More)
Four halophilic archaeal strains, designated TNN18(T), TBN12, TNN28(T) and TBN19, were isolated from brines sampled from two artificial marine solar salterns in eastern China. Strains TNN18(T) and TNN28(T) were isolated from the Tainan marine solar saltern, whereas strains TBN12 and TBN19 were from the Taibei marine solar saltern. Colonies of the four(More)
