dc.description.abstract | Thousands of net-heterotrophic and strongly stratifying lakes dominate the boreal landscape.
Besides their central role as emitters of greenhouse gases, we have only recently begun to
understand the microbial systems driving the metabolic processes and elemental cycles in these
lakes. Using shotgun metagenomics, we show that the functional potential differs among lake types,
with humic lakes being particularly enriched in carbon degradation genes. Most of the metabolic
pathways exhibit oxygen- and temperature-dependent stratification over depth, coinciding with
shifts in bacterial community composition, implying that stratification is a major factor controlling
lake metabolism. In the bottom waters, rare and poorly characterized taxa, such as ε-Proteobacteria,
but also autotrophs, such as photolithotrophic Chlorobia were abundant. These oxygen-depleted
layers exhibited high genetic potential for mineralization, but also for fixation of carbon and
nitrogen, and genetic markers for both methane production and oxidation were present. Our study
provides a first glimpse of the genetic versatility of freshwater anoxic zones, and demonstrates the
potential for complete turnover of carbon compounds within the water column. | fi |
