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 does a photobioreactor do?
A photobioreactor (PBR) is a bioreactor that utilizes a light source to cultivate phototrophic microorganisms. These organisms use photosynthesis to generate biomass from light and carbon dioxide and include plants, mosses, macroalgae, microalgae, cyanobacteria and purple bacteria.
Which type of photo is bioreactor?
There are various type of photobioreactors designed mainly for microalgae biomass production, such as (1) open system, which is normally known as raceway pond, and (2) closed system, which include tubular, bubble column, flat plate, and fermentor [78].
Is it expensive to grow algae?
An open-air algae pond costs an average of $32,500 per acre, according to industry experts. A 100-acre algae farm would set you back more than $3 million.
Why is photobioreactor important?
Compared to open systems, photobioreactors have a number of advantages: reproducible cultivation conditions with regard to environmental influences; reduced risk of contamination; low CO2 losses; and smaller area requirements.
Which is not a photobioreactor?
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.
What is Johnson-Su bioreactor?
His method is called BEAM (Biologically Enhanced Agricultural Management) and centers around the products created using the compost creation system he devised with his wife Hui-Chun Su (called the Johnson-Su Bioreactor). Compost is usually thought of fertilizer, a way of adding nutrients to the soil.
What is Johnson-Su composting?
The compost from Johnson-Su composting bioreactors improves seed. germination rates when used to coat seeds, improves soil water infiltration and water retention by helping to increase soil carbon content, and increases plant health, plant growth rates, and crop production.
What happens in a bioreactor?
Bioreactors are vessels that have been designed and produced to provide an effective environment for enzymes or whole cells to transform biochemicals into products. In some cases, inactivation of cells or sterilization is carried out in the bioreactor such as in water treatment.
What is the most productive algae?
An Alga That Has It All Picochlorum renovo was tested in outdoor raceway ponds in Mesa, Arizona, demonstrating sustained productivity among the highest reported to date in seawater media, and withstanding water temperatures close to 40°C (or 104°F) with solar light intensity of over 2,500 µE.
What is a photobioreactor?
The name photobioreactor is sometimes a bit too fancy actually. A photobioreactor can be the same as just a jar or bucket in which you grow your culture. However, a bucket or jar will not give you much of a yield or harvest and a good yield and good harvest are what you want.

What is a biofence™ photobioreactor?
The BioFence™ photobioreactor manufactured by Varicon-Aqua Solutions LTD, UK is a well engineered and reliable continuous algae culture system. I helped install and operate several of these systems for the US Fish and Wildlife Service for about 3 yrs.
