Short summary
A comparative analysis of the metagenomes from two 30,000-year-old permafrost samples, one of lake-alluvial origin and the other from late Pleistocene Ice Complex sediments, revealed significant differences within microbial communities. The late Pleistocene Ice Complex sediments (which are characterized by the absence of methane with lower values of redox potential and Fe2+ content) showed both a low abundance of methanogenic archaea and enzymes from the carbon, nitrogen, and sulfur cycles.
