Abstract

Using starch as a carbon source at a cultivation temperature of 4 °C, a number of Gram-negative, aerobic strains was isolated from sea-ice and sea-water samples collected at Spitzbergen in the Arctic. Analysis of the genetic diversity of the novel isolates by random amplification of polymorphic DNA (RAPD) and ERIC fingerprinting revealed a homogenic group of biofilm-forming bacteria that contained small extrachromosomal elements. As a representative of the group, strain Pull 5.3, isolated from a sea-water sample, was used for detailed characterization. The results of phylogenetic analysis indicated that the newly isolated strain is a member of the -subclass of the and belongs to the genus . On the basis of DNA–DNA hybridization experiments, chemotaxonomic studies and phenotypic characterization, strain Pull 5.3 (=CECT 5674 =DSM 14288) clearly represents a novel species, for which the name sp. nov. is proposed.
