| "candidatus thiobios zoothamnicoli," an ectosymbiotic bacterium covering the giant marine ciliate zoothamnium niveum. | zoothamnium niveum is a giant, colonial marine ciliate from sulfide-rich habitats obligatorily covered with chemoautotrophic, sulfide-oxidizing bacteria which appear as coccoid rods and rods with a series of intermediate shapes. comparative 16s rrna gene sequence analysis and fluorescence in situ hybridization showed that the ectosymbiont of z. niveum belongs to only one pleomorphic phylotype. the z. niveum ectosymbiont is only moderately related to previously identified groups of thiotrophic sy ... | 2006 | 16517650 |
| high genetic similarity between two geographically distinct strains of the sulfur-oxidizing symbiont 'candidatus thiobios zoothamnicoli'. | the giant marine ciliate zoothamnium niveum (ciliophora, oligohymenophora) is obligatorily covered by a monolayer of putative chemoautotrophic sulfur-oxidizing (thiotrophic) bacteria. for z. niveum specimens from the caribbean sea it has been demonstrated that this ectosymbiotic population consists of only a single pleomorphic phylotype described as candidatus thiobios zoothamnicoli. the goal of our study was to identify and phylogenetically analyse the ectosymbiont(s) of a recently discovered z ... | 2009 | 19120466 |
| the effects of sulphide on growth and behaviour of the thiotrophic zoothamnium niveum symbiosis. | zoothamnium niveum (ciliophora, oligohymenophora) is a giant, colonial marine ciliate from sulphide-rich, shallow-water habitats, obligatorily associated with the ectosymbiotic, chemoautotrophic, sulphide-oxidizing bacterium 'candidatus thiobios zoothamnicoli'. the aims of this study were to characterize the natural habitat and investigate growth, reproduction, survival and maintenance of the symbiosis from corsica, france (mediterranean sea) using a flow-through respirometer providing stable ch ... | 2007 | 17660153 |
