Metagenomic analysis of the microbial community at Zodletone Spring (Oklahoma): Insights into the genome of a member of the novel candidate division OD1

A metagenomic library was constructed from the anaerobic sediments of a mesophilic sulfur spring. Thirty-five bacterial 16S rRNA gene-containing clones were identified in this library. Analysis of a genomic fragment belonging to candidate division OD1 provided useful insights into the physiology and biochemistry of this novel, yet-uncultured candidate division.
