Genome sequence of Oceanobacillus picturae strain S1, an halophilic bacterium first isolated in human gut.

ABSTRACT: Oceanobacillus picturae is a strain of a moderately halophilic bacterium, first isolated from a mural painting. We demonstrate, for the first time, the culture of human Oceanobacillus picturae, strain S1(T), whose genome is described here, from a stool sample collected from a 25-year-old Saoudian healthy individual. We used a slightly modified standard culture medium adding 100 g/L of NaCl. We provide a short description of this strain including its MALDI-TOF spectrum, the main identification tool currently used in clinical microbiology. The 3,675,175 bp long genome exhibits a G?+?C content of 39.15 % and contains 3666 protein-coding and 157 RNA genes. The draft genome sequence of Oceanobacillus picturae has a similar size to the Oceanobacillus kimchii (respectively 3.67 Mb versus 3.83 Mb). The G?+?C content was higher compared with Oceanobacillus kimchii (respectively 39.15 % and 35.2 %). Oceanobacillus picturae shared almost identical number of genes (3823 genes versus 3879 genes), with a similar ratio of genes per Mb (1041 genes/Mb versus 1012 genes/Mb). The genome sequencing of Oceanobacillus picturae strain S1 isolated for the first time in a human, will be added to the 778 genome projects from the gastrointestinal tract listed by the international consortium Human Microbiome Project.

Project description:Two Gram-positive, rod-shaped moderately halophilic bacterial strains, designated AD7-25(T) and AB-11, were isolated from Aiding and Manasi salt lakes in Xinjiang of China, respectively. The strains were found to be able to grow at NaCl concentrations of 0-21 % (w/v), with optimum growth occurring at 6-8 % (w/v) NaCl. The optimal temperature and pH for growth were determined to be 33-37 °C and pH 7.0-7.5. Cells of the strains are motile by means of polar flagella. Both strains can produce ellipsoidal spores. The major cellular fatty acids were identified as anteiso-C15:0, iso-C15:0, iso-C14:0, anteiso-C17:0 and iso-C16:0. The diamino acid in the peptidoglycan and the major quinone system were determined to be meso-diaminopimelic acid (meso-DAP) and MK-7, respectively. The DNA G+C contents of stains AD7-25(T) and AB-11 were 39.8 and 40.0 mol%, respectively. Phylogenetic analysis based on 16S rRNA gene sequences revealed that these two novel strains are closely related to the genus Oceanobacillus showing 90-99.5 % similarity with respect to type strains. These two novel strains were most closely related to Oceanobacillus oncorhynchi subsp. incaldanensis DSM 16557(T) (99.1 and 99.5 %), followed by O. oncorhynchi subsp. oncorhynchi JCM 12661(T) (99.1 and 99.4 %), Oceanobacillus neutriphilus CGMCC 1.7693(T) (97.0 and 97.5 %), Oceanobacillus sojae JCM 15792(T) (97.6 and 98.0 %) and Oceanobacillus locisalsi KCTC 13253(T) (96.5 and 96.9 %). The DNA-DNA hybridization data indicated that DNA relatedness between strains AD7-25(T) and AB-11 was 91.0 %, and the genomic homology of representative strain AD7-25(T) with O. oncorhynchi subsp. incaldanensis DSM 16557(T), O. oncorhynchi subsp. oncorhynchi JCM 12661(T), O. neutriphilus CGMCC 1.7693(T), O. sojae JCM 15792(T) and O. locisalsi KCTC 13253(T) were 41, 39, 20, 23 and 17 %, respectively. On the basis of phenotypic and phylogenetic distinctiveness, strains AD7-25(T) and AB-11 should be assigned to the genus Oceanobacillus as a new species, for which the name Oceanobacillus aidingensis sp. nov. was proposed. The type strain is AD7-25(T) (=CGMCC 1.9106 (T) = NBRC 105904(T)).
