| 英文摘要 | Two novel Gram-stain-negative, aerobic and non-motile rods bacteria, designated TQ8S(T) and ZH2S(T), were isolated from salt marsh sediment collected from the Tibetan Plateau. Strain TQ8S(T) was found to grow at 10-40 degrees C (optimum, 30 degrees C), pH 6.0-11.0 (optimum, pH 8.0-9.0) and in the presence of 2-12% (w/v) NaCl (optimum, 6-8%). Strain ZH2S(T) was found to grow at 15-40 degrees C (optimum, 30 degrees C), pH 7.0-10.0 (optimum pH 9.0) and in the presence of 2-10% (w/v) NaCl (optimum, 4-6%). Phylogenetic analysis based on the 16S rRNA gene sequences showed that strains TQ8S(T) and ZH2S(T) shared 99.07% sequence similarity between each other and were affiliated with the genus Halomonas, sharing 97.48 % and 97.41% of sequence similarity to their closest neighbour Halomonas sulfidaeris Esulfide1(T), respectively. DNA-DNA hybridization analyses showed 61.0% relatedness between strains TQ8S(T) and ZH2S(T). The average nucleotide identity and the average amino acid identity values between the two genomes were 92.33 and 92.84%, respectively. The values between the two strains and their close phylogenetic relatives were all below 95 %. The major respiratory quinones of strain TQ8S(T) were Q-9 and Q-8, while that of ZH2S(T) was Q-9. The main fatty acids shared by the two strains were C-18:1 omega 6c and/or C-18:1 omega 7c, C-16:1 omega 6c and/or C-16:1 omega 7c, C-16:0 and C-12:0 3-OH. Strain ZH2S(T) can be distinguished from TQ8S(T) by a higher proportion of C-19:0 cyclo omega 8c. The G+C content of the genomic DNA of strains TQ8S(T) and ZH2S(T) were 57.20 and 57.14 mol%, respectively. On the basis of phenotypic distinctiveness and phylogenetic divergence, the two isolates are considered to represent two novel species of the genus Halomonas, for which the names Halomonas rituensis sp. nov (type strain TQ8S(T)=KCTC 62530(T)=CICC 24572(T)) and Halomonas zhuhanensis sp. nov (type strain ZH2S(T)=KCTC 62531(T)=CICC 24505(T)) are proposed. |
