Qualifications
Isabel Soares Silva graduated in Applied Biology at Minho University and latter obtained a specialisation in Molecular Genetics. She finished her PhD in 2006 in the field of Yeast Molecular Biology. In her subsequent PostDoc she specialized in the field of structure-function studies of permeases working in Minho Univ. and in the George Diallinas’ lab at Athens Univ, Greece. She then joined the Nephrology R&D Unit Porto Univ., as a research assistant, where she implemented a new research field that addressed catheter-related infections in dialysis patients, besides actively collaborating in ongoing group projects. Latter at the research Nephrology and Infectiology R&D group at INEB/I3S (UPorto) she focused on the characterisation of the Chronic Kidney Disease microbiome. Since October 2016 she has returned to the field of carboxylate transporters working on the project EcoAgriFood as an invited research assistant. She is now involved in the identification of novel transporter proteins for expression in biorefineries, and the production of value-added chemicals from biomass.
Research
At the present time I am interested in the identification and characterization of novel carboxylate transporters, with a potential biotechnological application. Several carboxylic acids are among the top value added chemicals produced from biomass, as these building-blocks can be subsequently converted to a number of high-value bio-based chemicals or materials. Different strategies have been developed to improve the cell factory production of these acids; however the export of these molecules is still a major bottleneck. In our group the study of carboxylic acid transporters has been one of the major focuses of research for several years now. The characterization of these transporters is done both at the functional and molecular levels. Transporter proteins are characterized by heterologous expression in a Saccharomyces cerevisiae strain with no carrier-mediated carboxylate transport at the plasma membrane. In addition, structure-function studies are conducted to unravel the mechanisms of substrate recognition and specificity of these proteins.
