Abstract

In the course of a screening programme in hypersaline habitats of southern Spain to isolate halophilic bacteria that are able to produce different extracellular enzymes, a novel, moderately halophilic bacterium (strain SM19) that displays lipolytic activity has been isolated and characterized. Strain SM19 is a Gram-negative rod that grows optimally in culture media that contain 7·5 % NaCl. The DNA G+C content was 57·0 mol%. According to phenotypic and genotypic data, this strain was assigned to the genus . However, 16S rDNA sequence similarity between strain SM19 and species of the genus was <96·7 %; this value is sufficiently low to propose its designation as a novel species. In addition, DNA–DNA hybridization with reference strains of close phylogenetic relatives was between 11 and 19 %. On the basis of these data, the inclusion of strain SM19 in the genus as a novel species is proposed, with the name sp. nov. The type strain of the novel species is SM19 (=DSM 15157=NCIMB 13907=CIP 107627=CCM 7048).
