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, ranging from industrial biotechnology to unconventional computing and living architecture. 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

Since we are largely committed in increasing the available computable reactome, we are involved in the high-quality metabolic modeling of a large set of metabolically diverse bacteria including P. putida KT2440, Synechocystis PCC6803, S. elongatus PCC7942, A. platensis, Azoarcus sp.CIB, S. granuli sp.TFA, P. pseudoalcaligenes CECT5344 and B. bacteriovorus HD100. This effort is enabling the system-level analysis of new metabolic processes while providing new computational test-beds for biotechnological applications. We are also interested in the inclusion of new metabolic modules and modelling approaches. Current efforts are targeted on i) the modeling of endogenous reactive oxygen species (ROS), ii) the implementation of dynamic condition-specific models and iii) the inclusion of posttranslational regulation.

System level analysis of Metabolic Robustness in bacteria

The robustness of a system is the property that allows it to maintain its functions despite external and internal perturbations. Through the metabolic modeling analysis of P. putida, we have recently identified metabolic cycles providing robustness to this bacterium. By using synthetic biology, ongoing efforts are focused on the rational engineering of such cycles under diverse biotechnological scenarios. In addition, we are increasing the metabolic robustness of P. putida by expanding its metabolic performance under oxygen limitation.

System level analysis and designing of microbial communities

The division of labor in microbial consortia allows an expanded complexity and functionality in bacteria. We are interested in: i) understanding how these expanded capabilities emerge within a community and ii) how we can engineer this community-level functionality towards biotechnological endeavors. To address these two fundamental questions we have developed a computational platform for modeling and engineering synthetic microbial consortia. Further implementation of these model-based designs is allowing us to develop new synthetic biology tools suitable for engineering microbial communities.
