Photobioreactors Boost MicroAlgae Production

Microalgae biotechnology is a trend setting industry with great potential for the future. This potential is evident in the manufacture of base materials for cosmetics, pharmaceuticals and food processing because algae are often superior to comparable synthetic materials that are used. In this regard, the combination of algae and glass may sound surprising at first. However, Photobioreactors, closed systems that grow microalgae for industrial purposes, is the technology that brings these two together. A collaborative venture between the Institut für Getreideverarbeitung GmbH and SCHOTT-Rohrglas GmbH (SCHOTT) has made it possible to improve existing systems while significantly reducing costs

In contrast to open systems such as ponds, closed systems offer the great advantage of minimized Carbon Dioxide, water and nutrient use while significantly reducing the risk of contamination. They also ensure a substantially higher product quality.

IGV photobioreactors are glass tubes connected via a U-shaped bend. Thanks to this modular design the system allows for efficient scaling to meet any requirements. The spectrum ranges from small test reactors to reactors for industrial applications.

In the course of its research, IGV has tested various materials and reactor systems and is convinced that glass tubing best meets its requirements. When compared to plastic, glass ensures a service life of up to four times longer in relation to light transmittance and wear and thus offers a higher yield. Therefore, photobioreactors made of glass tubing offer a longer production life under controlled conditions and maximize the final algae concentration for the system.

DURAN® from SCHOTT is resistant to chemical cleaning agents and facilitates decontamination of the system. In addition, DURAN® glass tubing offers a high resistance to thermal shock because of it's minimal rate of thermal expansion.
