Title:
CO2BioTech: PHBMAX - Maximized Biopolymer production with genetically modified Organisms using CO2
Duration:
01/01/2024 to 31/12/2026
Abstract / short description:
The project PHBMAX aims at developing biologically degradable polymer particles on the basis of polyhydroxybutyrate (PHB) through genetically modified cyanobacteria using waste-CO2 and and sunlight in mixed culture with other PHB producing bacteria.
In particular we target following aims:
- demonstration of the feasibility of co-cultivating cyanobacteria with other bacteria to enhance the yield of PHB for industrial use and to minimize contamination of the Bioreactor by competing organisms.
- Development of a robust PHB production with Synechococcus strains by transforming genetic modifications to enhance robustness of the process
- Introduction of further genetic modifications to modify the properties of PHB
- Use of waste CO2 as carbon source for the organism to minimize the environmental impact
- Demonstration of the use of whole cell material (including PHB) for industrial application
- Proof of concept of a climate-friendly, sustainable production of CO2-based polymers by establishing a complete life-cycle assessment and by a demonstration facility.
