UBA acid mine drainage site metagenome

Samples of pink biofilm and associated acid mine drainage were collected from the Richmond Mine, Iron Mountain, CA, from the Ultra Back A (UBA) site in June 2005. Iron Mountain is located at 40 deg 40' 38.42'' N and 122 deg 31' 19.90'' W (elevation ~ 3,100 ft). The UBA biofilm was subaerial, collected from the base of a ~2 m high pile of pyrite sediment over which pH 1.1, 41 deg C acid mine drainage solution was flowing. The first version of this project has a partial genome of Leptospirillum rubarum that dominates this biofilm (Genome Project 18795). A second partial genome from Leptospirillum ferrodiazotrophum is present in Genome Project 37907. The WGS project and sequences deposited into the Trace Archive can be found using the Project data link.
