DART: Distribution of Antibiotic Resistant microorganisms in municipal wastewater treatment plants (WWTP) equipped with a Tertiary step to remove micropollutants

The DART project intends to evaluate the fate of antibiotic resistant microorganisms and resistance genetic determinants in a municipal wastewater treatment plant (WWTP) that is subjected to a tertiary treatment process designed to remove micropollutants.  The aims are to understand if the tertiary treatment affects the distribution and the competitiveness of resistant microorganisms against the wastewater microflora and if it can decrease the risk of the release into surface waters of resistant bacteria and yeasts.

Il progetto è realizzato in collaborazione con il DTI (Dipartimento tecnologie innovative) della SUPSI

High-throughput Proteomics of Thiodictyon synthrophicum strain Cad16T

The goal is to elucidate the proteome of T. synthrophicum by a shotgun/bottom-up nanoUHPLC-MS/MS approach to better understand its role in the Cadagno Lake ecosystem.

Il progetto si svolge in collaborazione con la Divisione Biologia del Laboratorio Spiez dell'Ufficio federale della protezione civile, con la Zürich University of Applied Science e con la Mabritec AG (Riehnen).

Metabolic versatility of Phototrophic Sulfur Bacteria - implication in ecology of Lake Cadagno

 In the chemocline zone of Lake Cadagno, a vast bacterial phototrophic community, composed by Purple Sulfur Bacteria (PSB; family Chromatiaceae) and Green Sulfur Bacteria (GSB; family Chlorobiaceae), is present. Both groups oxidize sulfur compounds for anoxygenic photosynthesis, and could therefore be in competition due to sulfur as limiting element.
Our interest is focused on the possible metabolic evolution and adaptation of the two bacterial populations and on the relevance of their co-existence in the ecosystem of Lake Cadagno.
To answer these ecological questions we need to know the potential metabolism of each component of the microbial community.

Role of Aeromonas spp. in the environmental spread of resistance genes

The aquatic environment is a natural ecosystem that act as a reservoir, but also as a medium for the spread of resistance genes and their vectors. Since Aeromonads are natural inhabitant of water environments and some species are pathogenic for both humans and animals, they can be used as model to study the dissemination of resistant genetic determinants in the acquatic environment. The aim of this work is to evaluate the role played by Aeromonas spp. in the dissemination of antibiotic resistance determinants through mobile DNA elements, such as plasmids, integrons and transposons, in different aquatic environment.

Swiss Competence Centers for Energy Research (SCCER) - Exploitarion of biomass for energy recovery: energy from cheese production wastes (whey)

The aim of the project is the development and the implementation of a process for the production of energy as biogas from cheese wastewaters (whey). The good availability, the chemical characteristics in terms of high energy content, the need for treatment before environmental discharge, and ,up to now, the under-exploitation as a resource, make the cheese's whey one of the best feedstock for energy recovery
