Short CV

Research Interests

She has working relationships with national and international research groups, covering the following research areas:

1. Food microbiology: taxonomic, physiological and technological characterization of microflora isolated from fermented (dairy, baked, meat vegetable) products; microbiology of fresh produce. Use of PCR-based techniques for taxonomic and genetic polymorphism studies.

2. Stress response of lactic acid bacteria: use of fluorescence microscopy to assess the cell damage (membrane integrity and metabolic activity), SDS-PAGE and 2D-E techniques to assess the changes in protein profile (expression of protein involved in general and specific stress response mechanisms), and Real Time-PCR to evaluate the changes in gene expression.

3. Metabolism of lactic acid bacteria: study of regulation and activation of metabolic pathways in lactic acid bacteria through 2D-E, RT-PCR, NMR spectroscopy and chromatographic techniques. Investigation of pathways for organic acid and amino acid biosynthesis.

4. Predictive microbiology: optimization of fermentation processes (batch, fed-batch and continuous propagations of cell cultures in bioreactors) and use of predictive mathematical models to describe the effect of environmental factors on the microbial growth.

5. Application of multivariate statistical methods to identify and characterize microbial communities and to analyse the relationship between stress response patterns and changes in genotypic and proteomic profiles.
