| marine bacterial isolates inhibit biofilm formation and disrupt mature biofilms of pseudomonas aeruginosa pao1. | according to the centers for disease control and prevention, biofilms cause 65% of infections in developed countries. pseudomonas aeruginosa biofilm cause life threatening infections in cystic fibrosis infection and they are 1,000 times more tolerant to antibiotic than the planktonic cells. as quorum sensing, hydrophobicity index and extracellular polysaccharide play a crucial role in biofilm formation, extracts from 46 marine bacterial isolates were screened against these factors in p. aerugino ... | 2010 | 20665017 |
| effect of enzyme producing microorganisms on the biomass of epigeic earthworms (eisenia fetida) in vermicompost. | we analyzed the bacterial community structure of the intestines of earthworms and determined the effect of enzyme producing microorganisms on the biomass of earthworms in vermicompost. fifty-seven bacterial 16s rdna clones were identified in the intestines of earthworms by using polymerase chain reaction-denaturing gradient gel electrophoresis (pcr-dgge) analysis. entomoplasma somnilux and bacillus licheniformis were the dominant microorganisms; other strains included aeromonas, bacillus, clostr ... | 2011 | 21421302 |
| polymerase chain reaction-denaturing gradient gel electrophoresis analysis of bacterial community structure in the food, intestines, and feces of earthworms. | the bacterial communities in the food, intestines, and feces of earthworms were investigated by pcr-denaturing gradient gel electrophoresis (dgge). in this study, pcr-dgge was optimized by testing 6 universal primer sets for microbial 16s rrna in 6 pure culture strains of intestinal microbes in earthworms. one primer set effectively amplified 16s rrna from bacterial populations that were found in the food, intestines, and feces of earthworms. compared with the reference markers from the pure cul ... | 2011 | 21887635 |
| complete genome sequence of ferrimonas balearica type strain (pat). | ferrimonas balearica rossello-mora et al. 1996 is the type species of the genus ferrimonas, which belongs to the family ferrimonadaceae within the gammaproteobacteria. the species is a gram-negative, motile, facultatively anaerobic, non spore-forming bacterium, which is of special interest because it is a chemoorganotroph and has a strictly respiratory metabolism with oxygen, nitrate, fe(iii)-oxyhydroxide, fe(iii)-citrate, mno(2), selenate, selenite and thiosulfate as electron acceptors. this is ... | 2010 | 21304747 |
| polycyclic aromatic hydrocarbon-induced structural shift of bacterial communities in mangrove sediment. | mangrove sediment is well known for its susceptibility to anthropogenic pollution, including polycyclic aromatic hydrocarbons (pahs), but knowledge of the sediment microbial community structure with regards to exposure to pahs is limited. the study aims to assess the effects of pahs on the bacterial community of mangrove sediment using both 16s rdna polymerase chain reaction-denaturing gradient gel electrophoresis (pcr-dgge) and traditional enrichment methods. both the exposure time and the pah ... | 2009 | 18958515 |
| ferrimonas senticii sp. nov., a novel gammaproteobacterium isolated from the mucus of a puffer fish caught in kaneohe bay, hawai'i. | a novel species, strain p2s11t, was isolated from the mucus of a puffer fish caught off the coast of kaneohe bay, o'ahu, hawai'i. a phylogenetic analysis based on 16s rrna gene sequences showed that the novel strain was most closely related to ferrimonas marina dsm 16917t and ferrimonas balearica dsm 9799t with 93.5% and 82.9% sequence similarities, respectively, which established the novel strain as belonging to the genus ferrimonas. the strain formed off-white coloured colonies on marine agar ... | 2007 | 17978238 |
| ferrimonas futtsuensis sp. nov. and ferrimonas kyonanensis sp. nov., selenate-reducing bacteria belonging to the gammaproteobacteria isolated from tokyo bay. | two novel mesophilic, facultatively anaerobic, selenate-reducing bacteria, designated strains fut3661t and asr22-7t, were isolated from a sediment sample and the alimentary tract of littleneck clams, respectively. both sources of the samples were collected from the coast of tokyo bay, japan. cells were gram-negative rods and motile by means of a polar flagellum. the strains reduced selenate to elemental selenium (se0) and also reduced iron(iii) oxyhydroxide, iron(iii) citrate, arsenate, manganes ... | 2006 | 17082404 |
| ferrimonas marina sp. nov. | a novel ferrimonas species is described on the basis of phenotypic, chemotaxonomic and phylogenetic studies. four halophilic organisms were isolated from marine sand and marine macroalgae samples by using high-ph marine agar 2216. an analysis of the nearly complete 16s rrna gene sequences of these new isolates indicated that they were phylogenetically close (16s rrna gene sequence similarity >99.5%, gyrb gene sequence similarity >97.8%), and were most closely related to ferrimonas balearica (16s ... | 2005 | 16166677 |
| phylogenetic relationships among marine alteromonas-like proteobacteria: emended description of the family alteromonadaceae and proposal of pseudoalteromonadaceae fam. nov., colwelliaceae fam. nov., shewanellaceae fam. nov., moritellaceae fam. nov., ferrimonadaceae fam. nov., idiomarinaceae fam. nov. and psychromonadaceae fam. nov. | the phylogenetic relationships among marine alteromonas-like bacteria of the genera alteromonas, pseudoalteromonas, glaciecola, thalassomonas, colwellia, idiomarina, oceanimonas, oceanisphaera, shewanella, moritella, ferrimonas, psychromonas and several other genera of the 'gammaproteobacteria' were studied. results of 16s rrna gene sequence analyses revealed that some members of these genera formed several coherent groups at the family level. characteristic signature oligonucleotides for studie ... | 2004 | 15388743 |
| paraferrimonas sedimenticola gen. nov., sp. nov., a marine bacterium of the family ferrimonadaceae. | three strains (mok-106(t), mok-142 and mok-143) were isolated from marine sediment samples collected from the coast of okinawa island, japan. on the basis of 16s rrna gene sequence comparisons, the isolates were affiliated with the family ferrimonadaceae; shewanella denitrificans and ferrimonas balearica were the closest relatives, having sequence similarities of 93.7 and 93.0 %, respectively. the novel isolates shared high levels of 16s rrna gene sequence similarity with each other (98.7-99.3 % ... | 2007 | 17625182 |
