Abstract:
Unicellularalgae are attractive as a source of biofuels, since they are capable of highphotonic efficiency and grow in liquid culture, making it possible to harvestthem in bioreactors. However, any reactor with optical mean free paths longerthan that of a single cell will suffer from efficiency losses due to internalabsorbance and the fact that single cells are readily photodamaged at highflux.
Thenatural photo-symbiosis between algae and giant clams is extremely efficientand may show a path toward efficient bioreactor technology. In contrast toneighboring corals, the clam system absorbs almost all incident lightwith little or no fluorescence or waste. This efficiency seems largely due toforward-scattering cells in the clam called iridocytes. Intriguingly, thesurface distribution of iridocytes may be arbitrary and disordered, making ittrivial to mimic this function in technology. Inside the clam tissue,irradiance measurements showed that photons at ~ 600 nm are enhanced topenetrate the surface of the clam mantle. Therefore, the iridocytes areserving as solar energy transformers that provided a relativelyevenly-distributed-light environment in depth to maximize the energy usage foralgae at various positions.
