A two-year 16S rRNA amplicon analysis reveals the in-situ iron snow microbiome. Incubations of iron snow microcosms with 13C-CO2 metabolic labeling approach profile the dynamics of microbiome compositions over time (7, 14, 28 days) under oxic and anoxic conditions

Iron-rich pelagic aggregates (iron snow) are formed in the water column of lakes through adsorption of inorganic and organic matter. Abundant iron snow harboring bacteria and interspecies aggregation mechanisms between key players were characterized. To fully profile taxonomies of the in-situ iron snow microbiome in the water column, we collected iron snow samples in 2017 and 2018. We further incubated iron snow microcosms under oxic and anoxic conditions and profile the bacterial dynamics over time.
