title: water lake metagenome
design: 16S rRNA gene amplicon sequencing was performed to profile microbial communities in lake water and sediment samples collected in autumn from three high-altitude lakes in the Rila Mountains, Bulgaria. The V3-V4 hypervariable region of the 16S rRNA gene was amplified using primers 341F/806., and sequenced on the Illumina MiSeq platform using paired-end reads.
