Overcoming shear stress of microalgae cultures in sparged photobioreactors.
In the present work we identified and quantified the effect of hydrodynamic stress on two different microalgae strains, Dunaliella tertiolecta and D. salina, cultivated in bench-scale bubble columns. The cell death rate constant increased with increasing gas-entrance velocity at the sparger. Dunaliella salina was slightly more sensitive than D. tertiolecta. The critical gas-entrance velocities ...
متن کاملProduction of Carotenoids Using Microalgae Cultivated in Photobioreactors
Carotenoids comprise a diverse group of natural biomolecules with a plethora of beneficial effects. These compounds include potent bioantioxidants, provitamins, and safe colourants that are in high demand by pharmaceutical, cosmetic and food industries. A few species of unicellular algae (called carotenogenic microalgae) mainly the representatives of Chlorophyta, are among the richest biologica...
متن کاملHollow fibre membrane arrays for CO2 delivery in microalgae photobioreactors
Microalgae can serve as a carbon sink for CO2 sequestration and as a feedstock for liquid biofuel production. Methods for microalgal biomass and biofuel cultivation are progressing, but are still limited in the efficiency of light delivery and gas exchange within cultures. Specifically, current gas exchange methods are very energy intensive since they rely on mixing algal cultures at high flow ...
متن کاملTechnical insight on the requirements for CO2-saturated growth of microalgae in photobioreactors
Microalgal cultures are usually sparged with CO2-enriched air to preclude CO2 limitation during photoautotrophic growth. However, the CO2 vol% specifically required at operating conditions to meet the carbon requirement of algal cells in photobioreactor is never determined and 1-10% v/v CO2-enriched air is arbitrarily used. A scheme is proposed and experimentally validated for Chlorella vulgari...
متن کاملSlab waveguide photobioreactors for microalgae based biofuel production.
Microalgae are a promising feedstock for sustainable biofuel production. At present, however, there are a number of challenges that limit the economic viability of the process. Two of the major challenges are the non-uniform distribution of light in photobioreactors and the inefficiencies associated with traditional biomass processing. To address the latter limitation, a number of studies have ...
