摘要：The use of eco-technologies, such as duckweed insetting, for wastewater treatment is becoming popular because of its affordability and efficiency of pathogen removal. The purpose of the current research was to study the influence of Lemna minuta as a single plant in aquaponic recirculation system on the indicator microorganisms and pathogens in water. The aquaponic recirculation system consisted of 10 fish cultivation tanks and 4 plant tanks. The cleaning block of the system consisted of one mechanical filter (settling tank) and moving bed biofilter. Weekly samples of control water, fish tanks, and tanks with L. minuta were taken in four replicates. For the quantitative detection of some sanitary indicator microorganisms (coliforms, Enterobacteriaceae), pathogens (Salmonella spp.) and total count in the treated water, medium plates (Compact Dry EC; Compact Dry ETB; Compact Dry SL and Compact Dry TC, R- Biopharm AG, Germany) coated with dry culture medium were used.
