PSI Large-Scale Photobioreactors are systems that create an artificial environment for large-scale growing and harvesting of photosynthetic organisms, mostly algae. They are manufactured as modular systems that enable the customers to build their own cultivating apparatus according to their individual experimental needs.
PSI Photobioreactors feature a unique combination of the cultivator and monitoring device with user-friendly software control which offers remote control via internet. The core of the Photobioreactor system is a flat cultivation tank (100 L or 25 L working volume) with integrated temperature regulation in the range of 15 - 50 °C and bubble stirring (aeration) of the culture. Cultivation tanks may be built as modular systems containing number of optional modules and may be cascaded to increase the total volume up to 1000 L.
The modular Photobioreactors are designed to allow for precise control and optimization of the cultivation conditions by continuous monitoring of fluorescence parameters, photosynthetic efficiency, optical density of the culture and pH of the suspension for determining CO2 injection. The Photobioreactors assure control and monitoring of numerous parameters essential for successful culture cultivation and maximum production of biomass such as stable suspension temperature, homogenous light illumination and light spectral distribution. Photobioreactor function may also be enhanced by the two gas modules: Gas Mixing System GMS 150 providing optimal control of input gas concentration and composition; and Gas Analyzing Systems GAS 150 measuring CO2 concentration at the Photobioreactor output.
