dc.description.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, nosZI
, nosZII, amoAarchaea, and amoAbacteria). In both of the two studied lake sites,
the microbial community composition differed significantly between control point and
wastewater discharge point, and a gradual shift toward natural community composition
was seen downstream following the wastewater gradient. SourceTracker analysis
predicted that ∼2% of sediment microbes were of WWTP-origin on the study site where
wastewater was freely mixed with the lake water, while when wastewater was specially
discharged to the sediment surface, ∼6% of microbes originated from WWTP, but the
wastewater-influenced area was more limited. In nitrogen transformation processes, the
ratio between nitrifying archaea (AOA) and bacteria (AOB) was affected by wastewater
effluent, as the AOA abundance decreased from the control point (AOA:AOB 28:1 in
Keuruu, 11:1 in Petäjävesi) to the wastewater-influenced sampling points, where AOB
dominated (AOA:AOB 1:2–1:15 in Keuruu, 1:3–1:19 in Petäjävesi). The study showed
that wastewater can affect sediment microbial community through importing nutrients
and organic material and altering habitat characteristics, but also through bringing
wastewater-originated microbes to the sediment, and may thus have significant impact
on the freshwater biogeochemistry, especially in the nutrient-poor boreal ecosystems. | |
