Abstract
The phylogeny of Thiothrix ramosa based on 16S rRNA sequences was determined. This species is the first species in this genus that has been shown to be capable of autotrophic growth with reduced sulfur compounds as sole energy sources. T. ramosa forms a monophyletic clade with Thiothrix nivea, as determined by distance, parsimony, and maximum-likelihood methods. Both of these species clearly belong to the gamma subdivision of the Proteobacteria, where they are loosely associated with other sulfur-oxidizing chemoautotrophic organisms.Keywords
