Researchers Develop Low-Cost, Open-Source Bioreactor Platform for Synechocystis Cultivation

Strategic Insights -

A team of researchers at the Massachusetts Institute of Technology has successfully developed a low-cost, open-source bioreactor platform for cultivating Synechocystis sp. PCC 6803, a photosynthetic microbe with high potential for capturing excessive atmospheric carbon while generating valuable bioproducts. The bioreactor platform, which incorporates a photobioreactor, a lysis module, and a pressure-driven filtration setup, demonstrates a significant reduction in cost compared to commercial alternatives, making it an accessible solution for biomanufacturing research and sustainable cyanobacteria-derived glucose production.

Key Takeaways:

  • The bioreactor platform developed by the researchers is designed to cultivate Synechocystis sp. PCC 6803, a photosynthetic microbe with high potential for capturing excessive atmospheric carbon while generating valuable bioproducts.
  • The platform incorporates a photobioreactor, a lysis module, and a pressure-driven filtration setup, which provides an integrated system for Synechocystis cultivation and glucose extraction.
  • The system demonstrates a strong predictive accuracy with a mean absolute error and variance of 0.0009 +/- 0.0003 using a model developed to predict the growth based on measured environmental parameters.
  • The bioreactor platform achieves a biomass productivity of 90 mg L-1 day-1, with a specific growth rate of 0.166 day-1 and glucose concentrations up to 5.08 mg L-1 under an incident light intensity of approximately 400 mu mol m-2 s-1.
  • The system is estimated to have up to 65% reduction in cost compared to commercial alternatives, making it an accessible solution for biomanufacturing research and sustainable cyanobacteria-derived glucose production.
  • The platform was developed in collaboration with Inside Out LLC.
