In a series of workshops last year, we discussed the term ‘synthetic community’ and its usage. It’s so loosely defined and is regularly used to define something which in my eyes isn’t a SynCom. The discussion was also touching on whether the term itself is appropriate.

Real-time simultaneous monitoring of multiple analytes in bacterial cultures | Applied and Environmental Microbiology
Real-time monitoring of metabolites in bacterial cultures is crucial for advancing our understanding of microbial physiology, metabolic fluxes, and dynamic responses to environmental changes. This capability enables researchers to capture transient metabolic states that are often missed in endpoint measurements. The use of engineered periplasmic binding proteins as biosensors for this real-time metabolite monitoring represents a groundbreaking approach. By leveraging the natural specificity and high affinity of PBPs for small molecules, these biosensors can be engineered to detect a wide range of metabolites with exceptional sensitivity and temporal resolution. The integration of PBP-based biosensors into microbial research not only enhances our ability to study real-time metabolism but also provides a versatile tool for optimizing industrial bioprocesses and exploring bacterial infections and complex microbial ecosystems
