| ultrastructure and molecular phylogenetic position of a novel euglenozoan with extrusive episymbiotic bacteria: bihospites bacati n. gen. et sp. (symbiontida). | poorly understood but highly diverse microbial communities exist within anoxic and oxygen-depleted marine sediments. these communities often harbour single-celled eukaryotes that form symbiotic associations with different prokaryotes. during low tides in south-western british columbia, canada, vast areas of marine sand become exposed, forming tidal pools. oxygen-depleted sediments within these pools are distinctively black at only 2-3 cm depth; these layers contain a rich variety of microorganis ... | 2010 | 20482870 |
