gen. nov., sp. nov., an alkaliphilic, halotolerant bacterium isolated from a soda lake sediment Free

Abstract

A novel alkaliphilic, halotolerant, rod-shaped bacterium, designated strain YIM CH208, was isolated from a soda lake in Yunnan, south-west China. The taxonomy of strain YIM CH208 was investigated by a polyphasic approach. Strain YIM CH208 was Gram-negative, strictly aerobic and non-motile and formed red colonies. Optimal growth conditions were 28 °C, pH 8.5 and 0.5–2.5 % NaCl. Phylogenetic analysis based on 16S rRNA gene sequence comparisons showed that the isolate formed a distinct line within a clade containing the genus in the phylum and was related to the species and , with sequence similarity of 91.7 and 91.6 % to the respective type strains. The DNA GC content was 45.1 mol%. The major respiratory quinone was menaquinone-7 (MK-7). The predominant cellular fatty acids were iso-C 9 (19.9 %), C 3-OH (12.1 %), iso-C 3-OH (11.3 %), summed feature 3 (iso-C 2-OH and/or C 7; 10.7 %) and C 6 (8.7 %). On the basis of the phenotypic, chemotaxonomic and phylogenetic data, strain YIM CH208 represents a novel species of a new genus, for which the name gen. nov., sp. nov. is proposed. The type strain of is YIM CH208 (=ACCC 05414 =KCTC 22899).
