Abstract Marine macroalgae such as Ulva intestinalis have promising properties feedstock for cosmetics and pharmaceuticals. However, since the quantity quality of naturally grown algae vary widely, their exploitability is reduced – especially producers in high-priced markets. Moreover, expansion marine or shore-based cultivation systems unlikely Europe, sites either lie fishing zones, recreatio...

The first photobioreactors were born in the 1950s, and based on microalgae have potential applications pharmaceutical industry, food feed production, environmental engineering, wastewater treatment, renewable energy. Photobioreactors used pollutant treatment for carbon dioxide sequestration 1953 at Carnegie Institute Washington. use stable efficient algae cultivation technology to create an art...

An internally illuminated photobioreactor (IIPBR) design is proposed for energy-efficient biomass production. Theoretical rationale of the IIPBR design and its advantages over the traditional bubble column photobioreactors (PBRs) are presented, followed by experimental results from prototype scale cultivation of freshwater and marine algal strains in an 18L IIPBR. Based on theoretical considera...

The time-dependent optical properties of microalgae are crucial for light transfer in photobioreactor (PBR) designs. Here, the were derived using electromagnetic scattering theory informed by experimentally measured Chlorella protothecoides. temporal scaling functions (TSFs) nearly wavelength-independent absorption and cross-sections demonstrated theory, leading to first concrete expression TSF...
