| photobacterium aquimaris sp. nov., a luminous marine bacterium isolated from seawater. | two luminous marine bacteria, strains lc2-065(t) and lc2-102, were isolated from seawater at sagami bay in japan. these bacteria were gram-negative, oxidase-negative, catalase-positive, motile and coccoid-rods. 16s rrna gene sequence analysis and multilocus sequence analysis (mlsa) using six loci (ftsz, gapa, gyrb, mreb, pyrh and topa) and sequence analysis of the alpha subunit of luciferase (luxa) gene revealed that these bacteria were distinct from other species of the genus photobacterium. th ... | 2009 | 19502330 |
| crystal structures of the lumazine protein from photobacterium kishitanii in complexes with the authentic chromophore, 6,7-dimethyl- 8-(1'-d-ribityl) lumazine, and its analogues, riboflavin and flavin mononucleotide, at high resolution. | lumazine protein (lump) is a fluorescent accessory protein having 6,7-dimethyl-8-(1'-d-ribityl) lumazine (dmrl) as its authentic chromophore. it modulates the emission of bacterial luciferase to shorter wavelengths with increasing luminous strength. to obtain structural information on the native structure as well as the interaction with bacterial luciferase, we have determined the crystal structures of lump from photobacterium kishitanii in complexes with dmrl and its analogues, riboflavin (rbf) ... | 2010 | 19854891 |
| phylogeny, genomics, and symbiosis of photobacterium. | photobacterium comprises several species in vibrionaceae, a large family of gram-negative, facultatively aerobic, bacteria that commonly associate with marine animals. members of the genus are widely distributed in the marine environment and occur in seawater, surfaces, and intestines of marine animals, marine sediments and saline lake water, and light organs of fish. seven photobacterium species are luminous via the activity of the lux genes, luxcdabeg. much recent progress has been made on the ... | 2010 | 20883503 |
| determination of the genetic diversity of different bioluminescent bacteria by pulsed-field gel electrophoresis (pfge). | there are 4 different genera (i.e. vibrio, aliivibrio, photobacterium, and shewanella) in the new classification of bioluminescent bacteria. the mechanism of bioluminescence has yet to be fully elucidated. therefore, the determination of physiological and genetic characteristics of bioluminescent bacteria isolated from different sources is very important. pulsed-field gel electrophoresis (pfge) has the highest discriminatory power among the different molecular typing methods for the investigatio ... | 2015 | 26421141 |
| photobacterium angustum and photobacterium kishitanii, psychrotrophic high-level histamine-producing bacteria indigenous to tuna. | scombrotoxin fish poisoning (sfp) remains the main contributor of fish poisoning incidents in the united states, despite efforts to control its spread. psychrotrophic histamine-producing bacteria (hpb) indigenous to scombrotoxin-forming fish may contribute to the incidence of sfp. we examined the gills, skin, and anal vents of yellowfin (n = 3), skipjack (n = 1), and albacore (n = 6) tuna for the presence of indigenous hpb. thirteen hpb strains were isolated from the anal vent samples from albac ... | 2016 | 26826233 |
| paraphotobacterium marinum gen. nov., sp. nov., a member of the family vibrionaceae, isolated from surface seawater. | a novel gram-stain-negative bacterium, named strain nscs20n07dt, was isolated from surface seawater of the south china sea. cells of this strain contained poly-β-hydroxybutyrate granules. growth was observed at 15-35 °c with optimum of 30 °c, at a salinity range of 1-6 % (w/v) nacl with optimum of 3 % and at ph 5-8 with optimum of ph 5. the full-length 16s rrna gene sequence of strain nscs20n07dt showed highest similarity to photobacterium iliopiscarium atcc 51760t of 96.0 %, followed by photoba ... | 2016 | 27154455 |
| genetic diversity analysis of isolates belonging to the photobacterium phosphoreum species group collected from salmon products using aflp fingerprinting. | an accurate amplified fragment length polymorphism (aflp) method, including three primer sets for the selective amplification step, was developed to display the phylogenetic position of photobacterium isolates collected from salmon products. this method was efficient for discriminating the three species photobacterium phosphoreum, photobacterium iliopiscarium and photobacterium kishitanii, until now indistinctly gathered in the p. phosphoreum species group known to be strongly responsible for se ... | 2016 | 26513249 |
| photobacterium piscicola sp. nov., isolated from marine fish and spoiled packed cod. | five isolates from marine fish (w3(t), wm, w1s, s2 and s3) and three isolates misclassified as photobacterium phosphoreum, originating from spoiled modified atmosphere packed stored cod (ncimb 13482 and ncimb 13483) and the intestine of skate (ncimb 192), were subjected to a polyphasic taxonomic study. phylogenetic analysis of 16s rrna gene sequences showed that the isolates were members of the genus photobacterium. sequence analysis using the gapa, gyrb, pyrh, reca and rpoa loci showed that the ... | 2014 | 24951451 |
