Research summary

Our goal is deciphering the complexity of microbial metabolism, its evolutionary and biotechnological implications through a multidisciplinary approach. By assuming that the whole is greater than the sum of its parts, we aim to contribute to a better understanding of the emergent properties of microbial systems at subcellular, cellular and supracellular levels. We pursuit the rational re-design of these system properties towards novel biotechnological and medical applications.

Our foundational aim is the system-level understanding of microbial metabolism as a framework for developing a broad range of novel and non-intuitive biotechnological processes. Taking advantage of metabolic modelling, systems and synthetic biology we are addressing, at different levels, the understanding and full taming of bacterial systems emergence.

Increasing the completeness and scope of metabolic reconstructions

We are involved in the high-quality metabolic modeling of a large set of metabolically diverse bacteria including P. putida, S. elongatus, A. platensis, Azoarcus CIB, S. granuli, P. pseudoalcaligenes, B. bacteriovorus, H. influenzae and Bifidubacterium sps. This effort is enabling the system-level analysis of new metabolic processes while providing new computational test-beds for biotechnological applications. We are particularly interested in the inclusion of new metabolic modules such as the generation of reactive oxygen species, underground metabolisms and metabolic heterogeneity.

System-level analysis of Metabolic Robustness in bacteria

The robustness of a system is the property that allows it to maintain its functions despite perturbations. Through the metabolic modeling analysis of P. putida, we have identified metabolic cycles providing robustness. The synthetic biology assisted validation of such cycles is allowing the rational engineering of superior microbial biocatalyst under diverse biotechnological scenarios.

System-level analysis and designing of microbial communities

The division of labor allows an expanded complexity and functionality in bacteria. We are interested in: i) understanding how these expanded capabilities emerge within a bacterial populations and communities and ii) how we can engineer this supracellular-level functionality towards biotechnological endeavors. To address these two fundamental questions, we have developed systems and synthetic biology tools for modeling and engineering synthetic microbial populations and consortia. We are applying this technology in the revalorization of complex polymers such as lignin and plastic waste as well as in the cost effective production of plant-based secondary metabolites such as flavonoids.
