Microorganisms represent ideal candidates for synthetic and systems biology research because they can be manipulated with relative ease and they play essential roles in the environment, energy production and human health. The application and integration of both approaches had a strong impact on the field of microbial engineering, offering innovative strategies to study biological functions, as well as to design and optimize microbial cell factories. By combining the design of synthetic biological systems with the application of engineering principles, such as mathematical modelling and whole-system analysis, both systems and synthetic biology have been crucial to develop microbial platforms for the sustainable production of pharmaceuticals, biofuels or biomaterials, and other environmental applications (e.g. bioremediation processes). Important advances have been made for instance in the implementation of synthetic gene circuits for precise control of cellular processes and communication, the development of high-throughput screening technologies, or the integration of omics and computational modelling tools to engineer and model complex microbial traits. Moreover, being able to construct and program ‘synthetic microbial consortia’ can expand the range of biological functions performed by a microbial community, as well as their biotechnological applications.
Future research in this field holds the promise of further accelerating the development of microbial cell factories with enhanced productivity and versatility in the context of bioprocess scale-up, with potential to mitigate climate change challenges such as achieving sustainable energy security. In support of United Nations Sustainable Development Goal 9, SDG 9 (Industry, Innovation, and Infrastructure), BMC Microbiology launches the Collection, Synthetic and systems biology approaches applied to microbial engineering. We invite researchers to contribute with submissions focusing on leveraging synthetic and systems biology approaches to study, design and manipulate biological functions and metabolism in the context of microbial engineering. Topics of interest include, but are not limited to:
- Designing and bioengineering of microbial cell factories for control of cellular functions and metabolism
- Microbial cell factories for the production of recombinant proteins, pharmaceuticals, biofuels and biomaterials, and environmental applications (e.g. bioremediation processes)
