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.
