| Component | Prokaryotic Host | Integration Strategy | |-----------|----------------|----------------------| | | Cupriavidus necator (PHB), Pseudomonas spp. (mcl-PHA) | Fuse PhaC with phasin (PhaP) for granule binding; use dual-plasmid systems | | Carbon flux | TCA cycle ↔ fatty acid β-oxidation | Knockout fadB (β-oxidation) + overexpress fadD (acyl-CoA ligase) | | Precursor supply | Acetyl-CoA → 3HB (PHB) or (R)-3HA (mcl-PHA) | Integrate phaA , phaB operon under inducible promoter (e.g., P₁₅₅₃, Pₗₐc) |
| Challenge | Integration Fix | |-----------|----------------| | | Co-express phaP (phasin) + phaR (regulator) | | Cell lysis during accumulation | Integrate stress promoters (Pₙₐₜ, Pₒᵢᵣ) with anti-oxidant genes (sodB, katE) | | High residual biomass | Use fadBA knockout + wax ester synthase for byproduct rerouting | | Solvent waste in extraction | Integrate enzymatic lysis (lysozyme + achromopeptidase) + aqueous two-phase system (PEG/salt) | pha-pro integrations
Safeguards identified in a PHA study can be synchronized with Vertigo software . This integration is critical for developing safety requirement specifications and performing reliability calculations for automated safety systems. | Component | Prokaryotic Host | Integration Strategy
