Microbial Community Response on Wastewater Discharge in Boreal Lake Sediments.

ABSTRACT: Despite high performance, municipal wastewater treatment plants (WWTPs) still discharge significant amounts of organic material and nitrogen and even microbes into the receiving water bodies, altering physico-chemical conditions and microbial functions. In this study, we examined how nitrified wastewater affects the microbiology of boreal lake sediments. Microbial community compositions were assessed with next generation sequencing of the 16S rRNA gene, and a more detailed view on nitrogen transformation processes was gained with qPCR targeting on functional genes (nirS, nirK, nosZ_I, nosZ_II, amoA_archaea, and amoA_bacteria). In both of the two studied lake sites, the microbial community composition differed significantly
