Nitrogen cycling in the Lake Lugano North Basin & isotope effects during enzymatic nitrate reduction

The dataset accompanies the manuscripts "Microbial nitrogen removal versus recycling in the redox transition zone of a meromictic lake and its coupling to sulfur” and “Nitrogen and oxygen isotope effects during enzymatic nitrate reduction in vitro and by natural lake water consortia” Files: 16S rRNA gene sequencing data from the Lake Lugano North Basin and Lake La Cruz: - Mapping file - ASV table - Refseq file -Tree file - R Skript data import - R Skript relative abundance analysis - R Skript alpha and beta diversity analysis Isotope effects during nitrate reduction in incubation experiments with Escherichia coli and Pseudomonas sp. strains harboring narG and/or napA nitrate reductase genes: - Raw data, parameters (N-species concentrations and nitrate isotopes over time) - Raw data, values (N-species concentrations and nitrate isotopes over time) - Isotope effects, parameters (Nitrate reduction and nitrite production rates, Rayleigh isotope effects, Δδ18O:Δδ15N-NO3- ratios) - Isotope effects, values (Nitrate reduction and nitrite production rates, Rayleigh isotope effects, Δδ18O:Δδ15N-NO3- ratios)
