A Gram-negative, aerobic, motile rod, designated BZ93 T , was isolated from soil from an industrial site. The strain grew at 5-30 6C. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain BZ93 T was related to members of the genus Pseudomonas and was related most closely to Pseudomonas xiamenensis C10-2 T (97.8 % 16S rRNA gene sequence similarity) and Pseudomonas pertucinogena IFO 14163 T (97.4 %). The predominant cellular fatty acids of strain BZ93 T were C 18 : 1 v7c (54.8 %), summed feature 3 (C 16 : 1 v7c and/or iso-C 15 : 0 2-OH; 10.3 %), C 16 : 0 (9.9 %) and C 17 : 0 cyclo (7.4 %). The major quinone was ubiquinone 9. The major phospholipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol and an unknown phospholipid. The genomic DNA G+C content was 61.8 mol%. On the basis of phenotypic characteristics, phylogenetic analysis and DNA-DNA relatedness, a novel species, Pseudomonas bauzanensis sp. nov., is proposed. The type strain is BZ93 T (5DSM 22558 T 5CGMCC 1.9095 T 5LMG 26048 T ).The genus Pseudomonas was originally created by Migula (1894). Bacteria of the genus Pseudomonas belong to the Gammaproteobacteria and are aerobic, chemoorganotrophic, non-spore-forming, motile, Gram-negative rods with polar flagella and a respiratory rather than a fermentative metabolism (Palleroni, 1984;Timmis, 2002). Over the years, species of the genus have been reclassified and revised several times (Sneath et al., 1981;Oyaizu & Komagata, 1983;Vancanneyt et al., 1996;Anzai et al., 2000). Members of the genus Pseudomonas are widely distributed in soil, water, air, plants and many other natural habitats (Palleroni, 1992). Some representatives of this genus colonize cold habitats (Yumoto et al., 2001; Reddy et al., 2004;Bozal et al., 2007;Margesin et al., 2008). The present study deals with the characterization of a novel strain of the genus Pseudomonas that was isolated from soil and is able to grow at low temperatures. Strain BZ93 T was isolated from soil from an industrial site (containing high amounts of heavy oil and heavy metals) in Bozen, South Tyrol, Italy, as described previously (Zhang et al., 2010). The soil was sampled and processed under sterile conditions in spring 2008. A sample (10 g) was shaken with 90 ml sterile 1 % sodium pyrophosphate for 20 min at 150 r.p.m. Appropriate dilutions were prepared with sterile 0.9 % NaCl and 0.1 ml aliquots were spread on R 2 A agar (0.05 % yeast extract, 0.05 % peptone, 0.05 % Casamino acids, 0.05 % glucose, 0.05 % starch, 0.03 % sodium pyruvate, 0.03 % K 2 HPO 4 , 0.005 % MgSO 4 , 1.5 % agar; pH 7; Reasoner & Geldreich, 1985) and incubated at 20 u C. A white colony was purified and designated BZ93 T . Strain BZ93 T was routinely cultured on R 2 A medium at 20 u C and maintained as a suspension in skimmed milk (10 % w/v) at 280 u C. Pseudomonas pertucinogena LMG 1874 T and Pseudomonas xiamenensis CGMCC 1.6446 T were routinely grown on R 2 A agar at 25 u C and used as reference strains.DNA was extracted and purified as described b...
