The group focus is the study of microoganisms (bacteria, viruses and fungi) present in food and water matrices and their pathogenic potential and impact on the environment and human health. The group has a long track record in characterizing microbial populations thriving in food and water matrices using a multidisciplinary approach and applying the most recent technology.

Research Interests

Our current research interests are on the following main areas:

Food and water safety and quality

  • Study and characterize the microbial communities (bacterial, viral and fungal) present in food and water, regarding their pathogenic potential, always within the scope of food safety and quality.
  • Designing state of the art molecular biology and microbiology methods that overcome current technical difficulties in evaluating the presence of microbiological hazards in food and water.

Food and environmental microbiology

  • Study the ecophysiology of environmental microbial communities (present in matrices such as wastewater, spring and groundwater, and soil), characterizing their populations and analyzing their impact on the environment, food and, ultimately, human health.

Authenticity of food products

  • Devising molecular and microbiological methods for the assurance of traceability and authenticity

Microbiology of Man Made Environments

O objectivo principal do Laboratório Microbiology of Man-Made Environments é o estudo dos diferentes mciroorganismos (bactérias, virus e fungos) presentes em matrizes tais como alimentos, água como fontes de consumo humano e águas residuais. Este estudo tem em vista a análise do potencial patogénico que estas populações microbianas podem apresentar, quer na segurança alimentar quer no meio ambiente e, em última instância, na saúde humana. Igualmente o grupo tem uma forte componente de investigação quer ao nível da qualidade do alimento quer ao nível da autenticidade/rastreio deste.  As abordagens consideradas pelo grupo para enfrentar estes desafios têm tido uma perspectiva multidisciplinar, colaborando com engenheiros químicos e ambientais, bioquímicos e químicos para ampliar a possibilidade de responder às lacunas encontradas na investigação nesta área da Microbiologia. Devido ao conhecimento básico do grupo em técnicas de microbiologia e biologia molecular, essas são as principais ferramentas utilizadas para os estudos de populações microbianas de alimentos e água, processos de biorremediação ou produção de estirpes microbianas com impacto agrícola.
