How is a photobioreactor helpful to growing the algae?
Within the artificial environment of a photobioreactor, specific conditions are carefully controlled for respective species. Thus, a photobioreactor allows much higher growth rates and purity levels than anywhere in nature or habitats similar to nature.
How much does a photobioreactor cost?
between $70-150/ m2
Photobioreactors represent perhaps the highest cost item in algae cultivation. Photobioreactors are expensive owing to their sophistication. Currently (as of Aug 2010), Photobioreactor costs range between $70-150/ m2, though there some up and coming companies that claim to provide these at much lower capital costs.
What is the function of photobioreactor?
Photobioreactors behave as solar receivers. Any light absorbed by the photobioreactor walls or by the culture and not used in photosynthesis is converted into thermal energy, and may cause an increase of the culture temperature, resulting in culture failure even with tolerant species [26].
Which is not a photobioreactor?
1. Which of the following are not photobioreactor types? Explanation: Rotating wall vessel bioreactor is not a photo-bioreactor. The types of photo-bioreactors are Tubular, Christmas tree, plate, horizontal, foil, and porous substrate bioreactors.
How do you make a photobioreactor?
A very basic photobioreactor might make use of three one-liter bottles of purified water; sugar; brewer’s yeast; silicone sealant; drill; 6-mm aquarium airline tubing; and algae (see the Science Fair Project entitled “Carbon Dioxide and Algae” and submitted in this group.)
Why is airlift bioreactor used?
Airlift bioreactors are used for cell culturing, pallet form fermentation, and immobilized enzyme reactions. Typically, airlift bioreactors are used when the desired reactants and/or final products are in a gaseous state and for aerobic cell cultures.
