Title: Animal waste and antibiotic impacts on microbial denitrification in terrestrial and aquatic ecosystems


Name: Miguel Semedo


The global increase in livestock and poultry production in the last decades has led to an increase in animal waste generated. Animal waste contains high levels of nitrogen and may carry antibiotics that can disturb important microbial activities such as denitrification. In the terrestrial environment, denitrification is an important source and sink of N2O, a potent greenhouse gas. In aquatic ecosystems, denitrification is a dominant NO3- removal pathway, contributing to prevent eutrophication. In this seminar, I will present an overview of my PhD dissertation, where I examined the impacts of animal waste and potential antibiotic exposure on microbial denitrification in both ecosystems. A combined approach of measuring activity rates and performing a molecular characterization of the microbial communities will be described.
