| antibacterial compounds from marine vibrionaceae isolated on a global expedition. | on a global research expedition, over 500 bacterial strains inhibitory towards pathogenic bacteria were isolated. three hundred of the antibacterial strains were assigned to the vibrionaceae family. the purpose of the present study was to investigate the phylogeny and bioactivity of five vibrionaceae strains with pronounced antibacterial activity. these were identified as vibrio coralliilyticus (two strains), v. neptunius (two strains), and photobacterium halotolerans (one strain) on the basis o ... | 2010 | 21339958 |
| genomic sequence analysis of a plant-associated photobacterium halotolerans meld1: from marine to terrestrial environment? | mercury impacts the function and development of the central nervous system in both humans and wildlife by being a potent neurotoxin. microbial bioremediation is an important means of remediation of mercury-contaminated soil. the rhizospheric photobacterium halotolerans strain meld1 was isolated from mercury and dioxin contaminated site from tainan, taiwan. it has been shown to reduce hg(2+) to hg(0). the 4,758,027 bp genome of p. halotolerans meld1 has a g + c content of 50.88 % and contains 419 ... | 2016 | 27594975 |
| diversity and n-acyl-homoserine lactone production by gammaproteobacteria associated with avicennia marina rhizosphere of south indian mangroves. | the diversity of n-acyl-homoserine lactone (ahl)-producing rhizosphere bacterial community associated with avicennia marina in the mangrove ecosystems of south india was investigated. approximately 800 rhizobacteria were isolated from a. marina, and they were screened for the production of ahl using two biosensors, chromobacterium violaceum cv026 and agrobacterium tumefaciens ntl4 (pzlr4). among the total isolates screened, 7% of the rhizobacteria showed positive induction for ahl signals. the b ... | 2015 | 25956585 |
| genome sequence of photobacterium halotolerans meld1, with mercury reductase (mera), isolated from phragmites australis. | here, we present the whole-genome sequence of photobacterium halotolerans strain, meld1, isolated from the roots of a terrestrial plant phragmites australis grown in soil heavily contaminated with mercury and dioxin. the genome provides further insight into the adaptation of bacteria to the toxic environment from where it was isolated. | 2015 | 26044418 |
| biosynthetic products from a nearshore-derived gram-negative bacterium enable reassessment of the kailuin depsipeptides. | sampling of california nearshore sediments resulted in the isolation of a gram-negative bacterium, photobacterium halotolerans, capable of producing unusual biosynthetic products. liquid culture in artificial seawater-based media provided cyclic depsipeptides including four known compounds, kailuins b-e (2-5), and two new analogues, kailuins g and h (7 and 8). the structures of the new and known compounds were confirmed through extensive spectroscopic and marfey's analyses. during the course of ... | 2015 | 25699470 |
| draft genome sequence of photobacterium halotolerans s2753, producer of bioactive secondary metabolites. | we report here the whole draft genome sequence of marine isolate photobacterium halotolerans s2753, which produces the known antibiotic holomycin and also ngercheumicins and solonamides a and b, which interfere with virulence of methicillin-resistant staphylococcus aureus strains by interacting with the quorum-sensing system. | 2014 | 24926051 |
| solonamide b inhibits quorum sensing and reduces staphylococcus aureus mediated killing of human neutrophils. | methicillin-resistant staphylococcus aureus (mrsa) continues to be a serious human pathogen, and particularly the spread of community associated (ca)-mrsa strains such as usa300 is a concern, as these strains can cause severe infections in otherwise healthy adults. recently, we reported that a cyclodepsipeptide termed solonamide b isolated from the marine bacterium, photobacterium halotolerans strongly reduces expression of rnaiii, the effector molecule of the agr quorum sensing system. here we ... | 2014 | 24416329 |
| toxicity of bioactive and probiotic marine bacteria and their secondary metabolites in artemia sp. and caenorhabditis elegans as eukaryotic model organisms. | we have previously reported that some strains belonging to the marine actinobacteria class, the pseudoalteromonas genus, the roseobacter clade, and the photobacteriaceae and vibrionaceae families produce both antibacterial and antivirulence compounds, and these organisms are interesting from an applied point of view as fish probiotics or as a source of pharmaceutical compounds. the application of either organisms or compounds requires that they do not cause any side effects, such as toxicity in ... | 2014 | 24141121 |
| photobacterium galatheae sp. nov., a bioactive bacterium isolated from a mussel in the solomon sea. | a novel, gram-negative marine bacterium, s2753t, was isolated from a mussel of the solomon sea, solomon islands. analysis of the 16s rrna gene sequence and whole genome sequence data placed strain s2753t in the genus photobacterium with the closest relative being photobacterium halotolerans dsm 18316t (97.7 % 16s rrna gene similarity). strain s2753t was able to grow from 15 to 40 °c and in nacl concentrations of 0.5 to 9 % (w/v). the predominant fatty acids were 16 : 1ω7c/16 : 1ω6c (27.9 %), 16 ... | 2015 | 26374506 |
