show Abstracthide AbstractPurple microbial (Photo- and chemosynthetic) mats found in low-oxygen/high-sulfur sink holes located in Lake Huron, MI. Cyanobacteria in the mats are capable of anoxygenic photosynthesis as well as oxygenic photosynthesis. This project includes sequence data submitted in 4 separate organism bins: MIS-Ph1 (close to complete genome for a Phormidium sp.), MIS-Ph2 (a second bin for an incomplete genome of Phormidium sp.), MIS-Os (bin of Oscillatoria spp.) and MIS-Unclassified (bin of unclassified sequences).
