Photobioreactor FMT 150 features a unique combination of the cultivator and computer controlled monitoring device. It is primarily designed for modular and precise phototrophic cultivation of algae, cyanobacteria and bacteria. Light power and spectral composition as well as temperature and aeration gas composition can be set with high accuracy.

User defined cultivation conditions can be dynamically varied according to user-defined protocols. Continuous online monitoring of cultivation conditions and measured parameters is possible via the Photobioreactor control unit including a notebook with pre-installed software (since May 2015 BASIC or ADVANCED editions are offered). Light, temperature, gas composition, and culture medium regime can be programmed to oscillate with various amplitudes and frequencies with user-defined time steps from milliseconds to hours via the software or via the control unit. Continuous-flow turbidostatic cultivation can be used for the stabilization of the suspensions via optical density control. In addition, up to 7 peristaltic pumps for different chemostat or pH-stat cultivation control can be linked to the Photobioreactor FMT 150 for the highly precise control of cultivation conditions.

Growth of cultures is monitored by the integrated densitometer (OD 720 nm, 680 nm). Relative chlorophyll content of cultures can also be monitored continuously by the difference of optical densities at 680 and 720 nm. Instantaneous physiological state of the culture is measured by the Photosystem II quantum yield Fv/Fm.

The Photobioreactor FMT 150 has a flat-vessel design that enables uniform illumination over the whole culture. Small-scale Photobioreactors are currently manufactured in three versions differing in the volume of their cultivation vessels: 400 ml, 1000 ml and 3000 ml.
