Draft Genome Sequence of the Moderately Halophilic Bacterium Pseudoalteromonas ruthenica Strain CP76

Abstract

Pseudoalteromonas ruthenica strain CP76, isolated from a saltern in Spain, is a moderately halophilic bacterium belonging to the Gammaproteobacteria. Here we report the draft genome sequence, which consists of a 4.0-Mb chromosome, of this strain, which is able to produce the extracellular enzyme haloprotease CPI.

Antimicrobial‐producing Pseudoalteromonas from the marine environment of Panama shows a high phylogenetic diversity and clonal structure

“…B) isolated from sponges and octocorals from Punta Galeta and Coiba National Park are closely related to P. ruthenica , a species previously isolated from saltern environments and mussels, with antimicrobial activity against several marine bacteria . Studies have reported the production of haloprotease CPI in this species, suggesting that it aids the species in coping with extreme habitat conditions . Four pigmented clonal lineages (35, 37, 40, and 42) are closely related to the opportunistic fish pathogen Pseudoalteromonas piscicida .…”

Six Pseudoalteromonas Strains Isolated from Surface Waters of Kabeltonne, Offshore Helgoland, North Sea

“…Members of the genus Pseudoalteromonas ( Gammaproteobacteria ; Alteromonadales ; Alteromonadaceae ) are Gram-negative aerobic chemoorganoheterotrophs of marine microbial communities ( 1 ). They span habitats ranging from surface ( 2 ) to deep sea ( 3 ), polar waters ( 4 ) and sea ice ( 5 ), and temperate salterns ( 6 ). While comprising up to 6% of free-living seawater communities in polar regions ( 2 ), Pseudoalteromonas spp.…”
