Abstract. Photobioreactors can be used to produce biofuels by growing microalgae in a controlled environment. The control factors are pH, CO2, light and nutrients. Among these factors, light is the primary source of energy for photoautotrophic microorganism growth. Therefore, the most important factor in microalgae production is achieving an efficient

Internal Gas Exchange Photobioreactor
2007Two eight-tube internal gas exchange photobioreactors were deployed on an inclined platform at an ocean-front research facility in Honolulu, Hawaii. The photobioreactors consisted of 3.8-cm inside diameter, 20-m long tubes joined at the bottom to a manifold aerator and at the top to a degassing reservoir, with a total volume of 230 L and a nominal ...

Photobioreactors with Internal Illumination
2015There has been an increasing commercial interest in phototrophic culturing of microalgae for all-year biomass production for food and feed supplements, as a source of valuable and bioactive compounds, and most recently biofuels. Indoor photobioreactors (PBRs) with artificial illumination make it possible to grow microalgae strains under well-controlled

Hydrodynamic conditions in designed spiral photobioreactors
Bioresource Technology, 2010In this work, a series of spiral tube PBRs were introduced. Flow dynamics of microalgae fluid, light intensity histories of tracked cells and swirl numbers within the spiral PBRs were numerically simulated. Results show that strong swirl motions are formed in the cross-sections along axial coordinate of spiral PBRs, but no such vortice is observed for ...

Tubular photobioreactor design for algal cultures
Journal of Biotechnology, 2001Principles of fluid mechanics, gas-liquid mass transfer, and irradiance controlled algal growth are integrated into a method for designing tubular photobioreactors in which the culture is circulated by an airlift pump. A 0.2 m(3) photobioreactor designed using the proposed approach was proved in continuous outdoor culture of the microalga Phaeodactylum

Photobioreactors for mass cultivation of algae
Bioresource Technology, 2008Algae have attracted much interest for production of foods, bioactive compounds and also for their usefulness in cleaning the environment. In order to grow and tap the potentials of algae, efficient photobioreactors are required. Although a good number of photobioreactors have been proposed, only a few of them can be practically used for mass ...

Continuous microalgae cultivation in a photobioreactor
Biotechnology and Bioengineering, 2012AbstractNew biomass sources for alternative fuels has become a subject of increasing importance as the nation strives to resolve the economic and strategic impacts of limited fossil fuel resources on our national security, environment, and global climate. Algae are among the most promising non‐food‐crop‐based biomass feedstocks.

Abstract. A photobioreactor (PBR) can be used to produce biofuels by growing microalgae in a controlled environment where pH, CO2, light and nutrients are controlled. Light plays an important role in microalgal growth and production. How light attenuates with the PBR depth, different air flow rates and different biomass concentrations was determined ...
