sp. nov., a moderately halophilic bacterium from Rambla Salada, a Mediterranean hypersaline rambla Free

Abstract

A moderately halophilic bacterium (strain RS-16) was isolated from saline soil in Rambla Salada, a Mediterranean hypersaline rambla in Murcia, south-east Spain. Cells of strain RS-16 were Gram-negative rods, oxidase-negative and motile by peritrichous flagella. Strain RS-16 required NaCl for growth, and grew between 1 % and 30 % (w/v) NaCl (optimum, 5–7.5 %), at temperatures of between 4 °C and 41 °C (optimum, 32–37 °C), and at pH values of between 5 and 10 (optimum, pH 7). Strain RS-16 was chemo-organotrophic and its metabolism was respiratory with oxygen and nitrate as terminal electron acceptors. It produced acids from -glucose and -inositol, accumulated poly-β-hydroxyalkanoate granules and produced cream colonies on MY 7.5 % (w/v). The DNA G+C content of strain RS-16 was 56.2 mol%. A comparison of 16S rRNA gene sequences confirmed the relationship of strain RS-16 to species of the genus . The most phylogenetically related species was SP4 (97.4 %16S rRNA gene sequence similarity). In DNA–DNA hybridization assays strain RS-16 showed DNA–DNA relatedness values of 62.7±3.09 %, 64.5±1.97 % and 64.7±1.74 % to CECT 7282, CECT 7284 and CECT 7283, respectively. The major fatty acids of strain RS-16 were Cω7 and C, and the predominant respiratory lipoquinone was ubiquinone, with nine isoprene units (Q-9). On the basis of these data, strain RS-16 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is RS-16 ( = CECT 7896 = LMG 26647).
