title: Phylogenetic relationships of a large marine Beggiatoa.
abstract: Based upon 16S rRNA sequence and phenotypic similarities, a large, uncultured Beggiatoa sp. from the Bay of Concepción (Chile), is very closely related to the Chilean Thioploca species Thioploca araucae., whose filaments grow as sheathed bundles. The formation of sheathed filament bundles, the key character to distinguish the genus Thioploca from Beggiatoa, places closely related filamentous sulfur-oxidizing bacteria into two different genera, incongruent with 16S rRNA-defined clades.
