Photobioreactors allow for exquisite control of your phototrophic bioprocess to optimize photosynthetic efficiency, biomass production, and high value products.
How does a photobioreactor work?
Photobioreactors are specialized bioreactors for culturing phototrophic organisms. Given the correct conditions, almost any algae, cyanobacteria, seaweed, or plant cell can be grown efficiently in a photobioreactor. The ability to control carbon dioxide, temperature, nutrients, mixing, and light intensity in a bioreactor means that the organism in question can achieve much higher biomass than in nature.
Applications for Photobioreactors
Applications for photobioreactors include growing algae and cyanobacteria for biofuels, bioplastics, pharmaceuticals, nutriceuticals, food additives, carbon capture, and waste water remediation.
Applications for Photobioreactors include:
- Culturing Macro and Micro Algae
- Cyanobacteria and purple bacteria
- Seaweed, plant cells, and bryophytes
- Waste water remediation
- Hydrogen gas production (biorefineries)
- Algal alcohols and oils as biofuels
- Production of Biomolecules (polysaccharides, amino acids, isoprenoids, phenols, etc…)
- Bioplastics, organic renewable replacements for petrochemical products
- Aquaculture (animal feed, human nutrition, value added products)
- Carbon Capture (sinking carbon to mitigate climate change)
- Pharmaceutical applications (drug discovery, bioactive molecules, vaccine production, etc…)
Challenges of Using Photobioreactors
Traditional bioreactor designs face challenges in delivering process efficiencies. Challenges using a photobioreactor include:
- Precisely controlling light intensity and temperature simultaneously.
- CO2 and gas diffusion constants.
- pH adjustment in real-time.
- Culture mixing.
- Nutrient addition.
- Evaporation and water loss.
- Sterility.
- Algae collection and aggregation.
- Scaleability and space requirements.
Solaris has uniquely addressed these challenges at a benchtop / lab scale.
