| enhanced biofilm formation and increased resistance to antimicrobial agents and bacterial invasion are caused by synergistic interactions in multispecies biofilms. | most biofilms in their natural environments are likely to consist of consortia of species that influence each other in synergistic and antagonistic manners. however, few reports specifically address interactions within multispecies biofilms. in this study, 17 epiphytic bacterial strains, isolated from the surface of the marine alga ulva australis, were screened for synergistic interactions within biofilms when present together in different combinations. four isolates, microbacterium phyllosphaer ... | 2006 | 16751497 |
| proteorhodopsin light-enhanced growth linked to vitamin-b1 acquisition in marine flavobacteria. | proteorhodopsins (pr) are light-driven proton pumps widely distributed in bacterioplankton. although they have been thoroughly studied for more than a decade, it is still unclear how the proton motive force (pmf) generated by pr is used in most organisms. notably, very few pr-containing bacteria show growth enhancement in the light. it has been suggested that the presence of specific functions within a genome may define the different pr-driven light responses. thus, comparing closely related org ... | 2016 | 26574687 |
| complete genome sequence of the proteorhodopsin-containing marine flavobacterium dokdonia donghaensis dsw-1t, isolated from seawater off dokdo in the east sea (sea of korea). | dokdonia spp. have been used for investigating the lifestyles of proteorhodopsin-containing photoheterotrophs and for understanding marine photobiology. here, we report the complete genome sequence of dokdonia donghaensis dsw-1(t) using the pacbio sequencing platform. it should provide a valuable resource for comparative genomic studies of marine life harboring microbial rhodopsins among others. | 2016 | 27491981 |
| Reclassification of the three Krokinobacter species into the genus Dokdonia as Dokdonia genika comb. nov., Dokdonia diaphora comb. nov. and Dokdonia eikasta comb. nov. and emended description of the genus Dokdonia Yoon et al. 2005. | The genera Dokdonia and Krokinobacter, members of the family Flavobacteriaceae in the phylum Bacteroidetes, were found to be phylogenetically closely related from the result of 16S rRNA gene sequence analysis. Dokdonia donghaensis DSW-1(T) exhibited 16S rRNA gene sequence similarity values of 99.3, 98.1 and 98.1 % to K. genikus Cos-13(T), K. diaphorus MSKK-32(T) and K. eikastus PMA-26(T), respectively. The major fatty acids (>10 % of the total fatty acids) found in the four strains were iso-C(15 ... | 2011 | 21984677 |
| constitutive expression of the proteorhodopsin gene by a flavobacterium strain representative of the proteorhodopsin-producing microbial community in the north sea. | proteorhodopsin (pr), a photoactive proton pump containing retinal, is present in approximately half of all bacteria in the ocean, but its physiological role is still unclear, since very few strains carrying the pr gene have been cultured. the aim of this work was to characterize pr diversity in a north sea water sample, cultivate a strain representative of north sea pr clusters, and study the effects of light and carbon concentration on the expression of the pr gene. a total of 117 pr sequences ... | 2010 | 20305030 |
| dokdonia donghaensis gen. nov., sp. nov., isolated from sea water. | two gram-negative, non-motile, non-spore-forming, slightly halophilic bacterial strains, dsw-1t and dsw-21, were isolated from sea water and subjected to a polyphasic taxonomic study. they grew optimally at 30 degrees c and in the presence of 2 % (w/v) nacl. strains dsw-1t and dsw-21 were characterized chemotaxonomically as containing mk-6 as the predominant menaquinone and iso-c15 : 0, iso-c17 : 0 3-oh and iso-c15 : 1 as the major fatty acids. their dna g+c content was 38 mol%. strains dsw-1t a ... | 2005 | 16280490 |
