Light in a Photobioreactor

2013 Kansas City, Missouri, July 21 - July 24, 2013, 2013
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

2007
Two 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

2015
There 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, 2010
In 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, 2001
Principles 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

A novel jet-aerated tangential swirling-flow plate photobioreactor generates microbubbles that enhance mass transfer and improve microalgal growth.

Bioresource Technology, 2019
To reduce bubble diameter and enhance mass transfer, a novel jet-aerated tangential swirling-flow plate photobioreactor was developed that improves the growth rate of microalgae.

Photobioreactors for mass cultivation of algae

Bioresource Technology, 2008
Algae 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, 2012
AbstractNew 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.

Light in a Photobioreactor

2014 ASABE Intersectional Meeting South Dakota, 2014
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 ...
