Monitoring proliferation and material production of Cupriavidus necator H16 using cell count and volume measurement.

ABSTRACT: Knallgas bacteria, including Cupriavidus necator H16, are promising cell factories for converting CO₂ into high-value compounds under autotrophic conditions. C. necator H16 synthesizes polyhydroxyalkanoates (PHA), a class of biodegradable plastics. However, the trade-off between cell proliferation and PHA production often limits productivity as a result of competition for cellular resources. Real-time monitoring of both processes is crucial for optimizing this balance. However, optical density (OD), a conventional metric for monitoring proliferation, is unreliable in organisms that accumulate intracellular products such as PHA. Traditional methods such as chromatography require complex sample preparation and are not suitable for real-time analysis. This study demonstrated that t
