Unicellular Algae TRIZ Cases
- Picochlorum Phosphite Dehydrogenase Expression
Expressing mutated ptxD and exogenous transporters in Picochlorum allows phosphite utilization, expanding genetic tools for mass cultivation.
- Chlorella protothecoides biomass sensory profile optimization
Heterotrophic fermentation of Chlorella protothecoides in darkness produces microalgal biomass with optimized sensory characteristics.
- Algae Cultivation Timing for Biomass Yield
Scheduled dilution and segmented nutrient delivery reduce cellular stress during light cycles, increasing biomass production.
- Algal Strain Screening for Photosynthetic Efficiency
Pre-screening identifies algal strains with optimized pigment content to overcome light saturation and boost biomass productivity.
- Alpha-glucosidase Enzyme Addition to Fermentation Broth
Alpha-glucosidase enzyme converts DP2+ sugars back into dextrose, resolving sterilization yield losses and boosting omega-3 production.
- Cyanobacterial Production of Ethylene Glycol via Enzymatic Conversion
Engineered cyanobacteria convert CO2 into ethylene, which bacteria transform to ethylene glycol, eliminating flammability risks in bioreactors.
- Microalgal Protein Enrichment via Glucose Limitation
Glucose deficiency slows growth while redirecting metabolic flux to boost protein content above 50%.
- Heterotrophic Chlorella Culture for Carotenoid Enrichment
Yeast extract diverts metabolic pathways in Chlorella, increasing carotenoid content by 0.4% without raising biomass quantity.
- Chlorella Biomass Decolorization via Growth Rate Control
Continuous fermentation controls growth rates to decolorize protein-rich Chlorella biomass.
- Microbial Oil Extraction Without Volatile Solvents
Replacing volatile organic solvents with non-flammable alternatives eliminates safety hazards and environmental pollution while recovering high-quality oils.
