Nitrogen fixing microbial communities in oiled and clean sands of Pensacola Beach, July 2010 and June 2011, and sugarcane and peat samples

These data report the diversity and composition of nitrogen-fixing microbial communities sampled from beach sands collected from Pensacola Beach. Nitrogen-fixers were characterized by the extraction, PCR amplification, and next generation sequencing of the nitrogenase gene (nifH). Sugarcane and peat samples were also analyzed.
